- CO2 and Photosynthesis. Carbon dioxide is a reactant in photosynthesis and is used during the light-independent reactions. ...
- Temperature and Photosynthesis. ...
What substance is the byproduct of photosynthisis?
The main product of photosynthesis is glucose, which is the molecule that produces energy to run the processes of the cell. Oxygen is mainly a byproduct of the process of photosynthesis. Six molecules of carbon dioxide and six molecules of water are needed to produce one molecule of glucose.
Which substance is a reactant in photisynthesis?
The products (outputs) of photosynthesis are the reactants (inputs) of cellular respiration. Some organisms perform photosynthesis but all organisms do cellular respiration. The purpose of photosynthesis is to convert light energy into chemical energy (glucose).
How do substances for photosynthesis enter the plant?
The reactants needed for photosynthesis are carbon dioxide and water; these are obtained through a combination of pores on leaves and root systems in the ground. These are eventually, through a process, turned into oxygen and glucose. The actual equation for photosynthesis is carbon dioxide plus water equals (in the presence of sun) a certain ...
What chemical reaction produces glucose?
During photosynthesis, carbon dioxide combines with released hydrogen, and together they form glucose. The chemical reactions that combine carbon dioxide and water to produce glucose are controlled by enzymes, which brings us to the fifth determining factor.
What happens if plants don't have enough light?
1.Light intensity. Without light, plants cannot photosynthesize, even if there is enough water and carbon dioxide in the environment. If light is poor, photosynthesis takes place more slowly.
What is the process of converting inorganic matter into organic matter?
Photosynthesis is the biochemical process by which plants convert inorganic matter into organic matter, taking advantage of energy from sunlight. This is the main nutrition process not only of plants but also of other autotrophic organisms endowed with chlorophyll, It is one of the most important biochemical mechanisms on ...
How do plants absorb water?
At the same time, the plant is fed through the roots. They absorb water and minerals that travel down the stem. Plants absorb carbon dioxide from the environment. The light absorbed by the chloroplasts helps the plant to easily divide the molecules in the water.
Why do plants need photosynthesis?
As we have already seen, photosynthesis serves, in principle, for plants to feed themselves, synthesizing organic matter from light energy. Thanks to this process, plants provide oxygen and renew the air, eliminating carbon dioxide or CO2.
How does photosynthesis produce energy?
3. Produces the transformation of light energy into chemical energy, necessary and used by living beings. 4.
What organs do plants use to make green?
To achieve this, plants use organs found in plant cells, called chloroplasts, which contain a pigment known as chlorophyll, it provides plants their characteristic green color. It also helps them capture light energy to transform it into chemical energy. The pigment called chlorophyll is green in color.
What Are The Requirements For Photosynthesis To Occur?

A Plant Cell
The outside of the cell which provides support and prevents the cell from bursting from the uptake of water.
Why is photosynthesis so important?
Photosynthesis is really important for animals, including humans because
Adaptations of the leaf
In most plants photosynthesis happens in the leaves. Leaves have adapted so that photosynthesis takes place efficiently. The table describes some of its adaptations:
Light
A leaf usually has a large surface area, so that it can absorb a lot of light. It's top surface is protected from water loss, disease and weather damage by a waxy cuticle, which does not stop light entering the leaf.
Carbon dioxide
Plants get the carbon dioxide they need from the air through their leaves. It moves by diffusion through small holes in the underside of the leaf called stomata. Guard cells control the size of the stomata so that the leaf does not lose too much water in hot, windy or dry conditions.
Water
The water needed for photosynthesis is absorbed through the roots and transported through tubes to the leaf. The roots have a type of cell called a root hair cell. These project out from the root into the soil, and have a big surface area and thin walls. This lets water pass into them easily.
Photosynthesis and respiration in plants
Plant cells respire, just as animal cells do. If they stop respiring, they will die.
What Is Not a Product of Photosynthesis?
If you're asked about photosynthesis on a test, you may be asked to identify the products of the reaction. That's pretty easy, right? Another form of the question is to ask what is not a product of photosynthesis. Unfortunately, this won't be an open-ended question, which you could easily answer with "iron" or "a car" or "your mom." Usually this is a multiple choice question, listing molecules which are reactants or products of photosynthesis. The answer is any choice except glucose or oxygen. The question may also be phrased to answer what is not a product of the light reactions or the dark reactions. So, it's a good idea to know the overall reactants and products for the photosynthesis general equation, the light reactions, and the dark reactions.
How many carbon dioxide molecules are produced in photosynthesis?
In photosynthesis, energy from light is used to convert carbon dioxide and water into glucose and oxygen. For 6 carbon dioxide and 6 water molecules, 1 glucose molecule and 6 oxygen molecules are produced. Actually, plants reserve very little of the glucose for immediate use. Glucose molecules are combined by dehydration synthesis ...
How does carbon dioxide enter a plant?
In a plant, the carbon dioxide enters via leaf stomates by diffusion. Water is absorbed through the roots and is transported to leaves through the xylem. Solar energy is absorbed by chlorophyll in the leaves. The reactions of photosynthesis occur in the chloroplasts of plants.
What is the function of chlorophyll in plants?
Chlorophyll in plant leaves converts carbon dioxide and water into the products glucose and oxygen. Connie Coleman/Getty Images
What is the name of the process that plants use to produce sugar?
Anne Marie Helmenstine, Ph.D. Updated January 24, 2020. Photosynthesis is the name given to the set of chemical reactions performed by plants to convert energy from the sun into chemical energy in the form of sugar. Specifically, plants use energy from sunlight to react carbon dioxide and water to produce sugar ( glucose) and oxygen.
What is the dark reaction?
The overall reaction for the light-dependent reactions is: In the dark stage, ATP and NADPH ultimately reduce carbon dioxide and other molecules. Carbon dioxide from the air is "fixed" into a biologically usable form, glucose. In plants, algae, and cyanobacteria, the dark reactions are termed the Calvin cycle.
What factors affect the rate of photosynthesis?
Factors That Affect the Rate of Photosynthesis. Like any chemical reaction, the availability of the reactants determines the amount of products that can be made. Limiting the availability of carbon dioxide or water slows the production of glucose and oxygen.
What gases do plants need for photosynthesis?
To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.
What 2 substances are needed for a plant to photosynthesis?
For photosynthesis to take place, plants need to take in carbon dioxide (from the air), water (from the ground) and light (usually from the sun).
What are the two gases that go in and out the Leaf?
Carbon dioxide and oxygen cannot pass through the cuticle, but move in and out of leaves through openings called stomata (stoma = “hole”). Guard cells control the opening and closing of stomata. When stomata are open to allow gases to cross the leaf surface, the plant loses water vapor to the atmosphere.
What kind of energy is required for photosynthesis to occur?
Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.
How do plants and animals take in gases?
By taking in water (H2O) through the roots, carbon dioxide (CO2) from the air, and light energy from the Sun, plants can perform photosynthesis to make glucose (sugars) and oxygen (O2). Just like you, plants need to take in gases in order to live. Animals take in gases through a process called respiration.
How is CO2 produced in photosynthesis?
CO2 gas is produced by burning carbon and organic compounds. It is also produced when plants and animals breathe out during respiration. Light: Even though both natural and artificial light is OK for plants, natural sunlight is best for photosynthesis because they have other natural UV properties that help the plant.
Why is sunlight important for photosynthesis?
Sunlight is needed for photosynthesis because the solar energy is what is converted to chemical energy by the plant's chloroplasts. This energy is necessary for the production of glucose, which provides usable energy for the plant. The chloroplasts contain the green pigment chlorophyll, which absorbs the sun's light.
How much energy does a wasp use?
The wasp converts sunlight into electrical energy. The efficiency of the conversion from sunlight into chemical energy is approximately 3 to 6 percent, with the unconverted energy being released as heat. Globally, it is estimated that photosynthesis captures about 130 terawatts of energy each year, which is six times larger than human energy ...
What are the two substances that are needed for photosynthesis?
The chloroplasts contain the green pigment chlorophyll, which absorbs the sun's light. Two other required ingredients for photosynthesis are carbon dioxide and water. The combination of these three substances fuels the process of photosynthesis, which produces glucose, oxygen and water.
Where does photosynthesis occur?
Photosynthesis occurs primarily in the leaves of the plants, which contain the highest concentration of chloroplasts. Tiny pores, or stomata, are also located on the plant's leaves and absorb carbon dioxide from the surrounding air. Protists, bacteria and blue-green algae are other organisms that photosynthesize for nourishment.
Do mollusks use photosynthetics?
Additionally, many organisms form symbiotic bonds with photosynthetic organisms, most commonly corals, sea anemones and sponges. Some mollusks even store chloroplasts in their bodies so that they can survive on sunlight alone for several months. In 2010, the Oriental hornet was the first animal discovered to use photosynthesis.
