What is photosynthesis answer?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
What is respiration and types?
Respiration is the process of gas exchange between the air and an organism's cells. Three types of respiration include internal, external, and cellular respiration. External respiration is the breathing process. It involves inhalation and exhalation of gases.
What is important of respiration?
The main purpose of respiration is to provide oxygen to the cells at a rate adequate to satisfy their metabolic needs. This involves transport of oxygen from the lung to the tissues by means of the circulation of blood.
Why is it called photosynthesis?
Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek phōs (φῶς), "light", and synthesis (σύνθεσις), "putting together".
What is photosynthesis explain with example?
An example of photosynthesis is how plants convert sugar and energy from water, air and sunlight into energy to grow. noun. 13. 8. (biology) The process by which plants and other photoautotrophs generate carbohydrates and oxygen from carbon dioxide, water, and light energy.
Why is photosynthesis important?
Photosynthesis sustains life on Earth today by releasing oxygen into the atmosphere and providing energy for food chains. The rise of oxygen-producing photosynthesis allowed the evolution of complex life forms like animals and land plants around 2.4 billion years ago.
What is respiration for 10th class?
Respiration is the process in which the cells of an organism obtain energy by combining oxygen and glucose, resulting in the release of carbon dioxide, water, and ATP (energy).
What is respiration class 6th?
Respiration is the process that all living things go through to create the energy they need to live. This happens in the cells so it is also called cellular respiration. It usually involves exchanging two gases—oxygen and carbon dioxide.
What is meant by respiration Class 7?
The process of breakdown of food in the cell with the release of energy is called cellular respiration. Cellular respiration takes place in the cells of all organisms. In the cell, the food (glucose) is broken down into carbon dioxide and water using oxygen.
What is respiration Class 11?
The process by which we release energy from organic compounds is known as Respiration. The released energy is then used for performing different physical activities. During respiration, the organic compounds are broken down internally into carbon dioxide and water.
How does photosynthesis work?
Photosynthesis is the process by which plants use light energy to convert carbon dioxide and water into sugars. The sugars produced by photosynthesis can be stored, transported throughout the tree, and converted into energy which is used to power all cellular processes. Respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy. This energy is used to fuel growth and all of the normal cellular functions. Carbon dioxide and water are formed as by-products of respiration (Figure 4).
How do plants get energy?
Plants convert energy from sunlight into sugar in a process called photosynthesis. Photosynthesis uses energy from light to convert water and carbon dioxide molecules into glucose (sugar molecule) and oxygen (Figure 2). The oxygen is released, or “exhaled”, from leaves while the energy contained within glucose molecules is used throughout the plant for growth, flower formation, and fruit development.
Does respiration require light energy?
Respiration occurs in all living cells, including leaves and roots. Since respiration does not require light energy, it can be conducted at night or during the day. However, respiration does require oxygen which can be problematic for roots which are overwatered or in soils with poor drainage. If roots are inundated for long periods of time they cannot take up oxygen and convert glucose to maintain cell metabolic processes. As a result, waterlogging and excessive irrigation can deprive roots of oxygen, kill root tissue, damage trees, and reduce yield.
What is the process of respiration and photosynthesis?
Respiration and Photosynthesis are two different processes that aim to create energy in living organisms. The process of respiration takes place in humans and animals and photosynthesis takes place in green plants. Both the processes help living organisms survive and maintain an equilibrium in the environment by providing all the necessary requirements.
Where does photosynthesis occur?
Photosynthesis occurs in the chloroplast. Chloroplasts are the organelles that are present in the cells containing chlorophyll. Whereas, respiration occurs in the cells of the bodies of living organisms.
Why is photosynthesis restricted to plants?
The process of photosynthesis is restricted to green plants only because of the presence of chlorophyll in the plant cells. This process doesn’t occur in other living beings like humans or animals.
Which process includes all living organisms while the process of photosynthesis takes place in green plants only?
The process of respiration includes all the living organisms while the process of photosynthesis takes place in green plants only.
What is the process by which green plants make food for themselves?
Photosynthesis is the process by which green plants make food for themselves.
What products are used to initiate the dark reaction which is formed during the light reaction of photosynthesis?
Ans: The products used to initiate the dark reaction which is formed during the light reaction of photosynthesis are ATP and NADPH. These products are used to fix CO 2 and to form a glucose molecule.
How does temperature affect photosynthesis?
All the enzymes act at a particular temperature. If the temperature increases beyond 35 °C, enzymes get denatured. Hence, the temperature affects the rate of photosynthesis.
What is the difference between respiration and photosynthesis?
Difference Between Photosynthesis And Respiration. Respiration is something that occurs in all living organisms. Thu s, it is a process that converts oxygen and glucose into carbon dioxide and water and ultimately makes energy for your body cells. On the other hand, photosynthesis takes place in green plants that contain chlorophyll.
What is the process of photosynthesis?

Further, it is a process occurring in chloroplasts making the use of chlorophyll. When we talk about the chemical formula, we see that the process needs six molecules of carbon dioxide and six molecules ...
What happens to hydrogen ions in water?
You will notice in the above reaction that hydrogen ions are released when oxidation of water in the presence of sunlight and oxygen happens. Thus, the removed hydrogen ions and electrons move to carbon dioxide and reduce as the organic product.
How many units of oxygen are needed for photosynthesis?
Thus, it results in creating a sugar chain and six units of oxygen. Moreover, chlorophyll is green as the light which photosynthesis requires is red and blue light.
What happens in the light and dark reaction?
It divides into two stages of light and dark reaction. The energy absorbs in the light reaction and transfers to electrons and produces ATP and reduction of NADPH. On the other hand, in dark reaction, the carbon dioxide reduces to organic carbon compounds with the help of ATP and NADPH.
Why does diffusion occur in alveoli?
As a result, diffusion takes place because of the difference in pressure between alveoli and blood.
How many stages are there in respiration?
Respiration is a complex process that has four stages. Firstly, there is glycolysis which means splitting or breaking of the sugar. After that, there is a transition reaction.
What is the difference between respiration and photosynthesis?
Differences between Photosynthesis and Respiration in table form: 1. It can only occur in plants, algae, and very few bacteria. It can occur In all organisms on earth. 2. It takes place only within the chloroplast. It takes place within the mitochondria. 3. It is an Anabolic kind of process.
How do respiration and photosynthesis work together?
Respiration and Photosynthesis are working complementary in nature. All this happens in such a way that plants use photosynthesis to produce oxygen. This oxygen is then used by all animals including humans to carry respiration on their end which gives carbon dioxide as a by-product. This by-product means carbon dioxide is then used by plants ...
What does photosynthesis produce?
Photosynthesis produces mainly two things, first oxygen as mentioned, and the second is glucose which is as a byproduct of photosynthesis.
What is the equation for photosynthesis?
Photosynthesis and Cellular Respiration Equation are as follow. Equation of Photosynthesis is C6H12O6 + 6O2 ~> 6CO2 + 6H2O and equation of Respiration is 6CO2 + 6H2O ~> C6H12O6 + 6O2. if You notice both these equations are reflecting each other that’s why we can say that respiration is reverse of photosynthesis.
What is the second product of photosynthesis?
Photosynthesis produces mainly two things, first oxygen as mentioned, and the second is glucose which is as a byproduct of photosynthesis. This glucose is stored as starch in plants. The quantity of glucose that plants use is lower than the glucose comes out after photosynthesis.

Most of the energy created through cellular respiration is transferred as positive electrons forming NADH+, ...
How is carbon dioxide converted into sugar?
Carbon dioxide is converted into sugars through a process known as carbon fixation, which is defined as the process of converting carbon dioxide to a solid compound. The simplest equation for photosynthesis can be summed up as such: Carbon dioxide + light energy → carbohydrates (sugar) + oxygen. See also cellular respiration word equation.
Why is photosynthesis important for living things?
Photosynthesis is a natural process that provides all aerobic creatures on earth with oxygen. Without photosynthesis, humans would cease to exist. Photosynthesis helps maintain a natural amount of oxygen in the atmosphere.
How do photosynthetic organisms produce food?

Plants, algae, and bacteria release oxygen after sugar is synthesized. Carbon dioxide is converted into sugars through a process known as carbon fixation, which is defined as the process ...
What are the requirements for photosynthesis?
So, the requirements for photosynthesis and therefore the creating of glucose needed for growth and respiration depends on the availability of carbon dioxide, water and light.
How does energy in plants work?
This energy produced is used to convert the glucose to other organic molecules and to take up mineral ions through roots. The concentration of minerals inside the plants are often higher than outside so energy is required to move against the concentration gradient. This would be like having a sink full of water with food colouring in it, putting a colander in the water and wanting the food colouring to accumulate in the colander. It’s not something that happens of its own accord.
How does water move through plants?
If you’ve ever seen a water cycle you will know that water vapour in the air increases through evaporation and through transpiration. Water is evaporated from the leaves of all plants. The movement of water through the plant is called the transpiration stream, which is important for: 1 Supplying the leaves with water for photosynthesis 2 Carrying minerals ions dissolved in the water (this would be how the plant gets nitrogen in the form of nitrates to make proteins or how the plant gets magnesium which is a component of chlorophyll). 3 Like sweating for us, water evaporates from the leaves, cooling the plant 4 Water is required to keep cells of the plant turgid, which is when a plant cell is ‘full’ of water. When the cells are not turgid the plant loses structure. This would be why your basil goes floppy when it’s lacking in water, but goes all rigid again after you’ve given it a drink.
What part of the leaf absorbs light energy?
Chlorophyll is a green pigment that absorbs the light energy required for photosynthesis to occur. Therefore, any green part can photosynthesise but it happens mainly in the leaves. They have a large surface area and take in carbon dioxide through pores in the underside of the leaf called stomata (singular stoma).
Why do plants transpire more in summer?
Also in summer, plants will transpire more in order to stay cool and just by having the stomata open for photosynthesis there will be loss of water out of these pores.
Why do plants need water?
Plants need water for photosynthesis. Water is a waste product of respiration. Transpiration is a necessary movement of water to supply photosynthesis, keep the plant cool, move mineral ions and keep the plant’s shape.
How is water absorbed by the roots?
Water is absorbed by the roots and then transported to the leaves via vessels called xylem. Glucose (the simple sugar that is synthesised) is then transported to all over the plant where it is needed via other vessels called phloem.
Where does energy stay in a plant?
Energy stays in the plant circle while the atoms regroup themselves into sugar and oxygen molecules, holding hands or linking arms to show that new bonds have formed.
What energy will be released when the CO2 and H2O bonds form?
Now have everyone regroup into carbon dioxide and water. The energy will be released as “heat ” when the CO2 and H2O bonds form and those students who represent energy will leave the animal by stepping outside the circle.
