What is photosynthesis short answer?
Process by which plants use the suns energy, water and carbon dioxide and turn it into sugar (glucose) Why is photosynthesis important to you and all living things?
What is the importance of photosynthesis in the environment?
Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy. The importance of photosynthesis in our life is the oxygen it produces. Without photosynthesis there would be little to no oxygen on the planet. TL;DR (Too Long; Didn't Read)
What is needed for photosynthesis to occur?
Photosynthesis requires light, carbon dioxide and water to be made. Carbon dioxide from the air enters the leaves of the plant thanks to the pores found in them. On the other hand, water is absorbed by the roots and moves to the leaves and the light is absorbed by the pigments of the leaves.
What are the products of photosynthesis in plants?
During these phases, the elements of photosynthesis, water and carbon dioxide, enter the plant and the products of photosynthesis, oxygen and sugar, leave the vegetable. First, the energy of light is absorbed by proteins found in chlorophyll.
What is the most important in photosynthesis?
Chlorophyll is responsible for the green color of plants. The thylakoid membrane encloses an internal space called the thylakoid space. Other types of pigments are also involved in photosynthesis, but chlorophyll is by far the most important.
What are the 3 main events of photosynthesis?
The three episodes that occur during the photosynthesis cycle are: Light energy is absorbed by chlorophyll, which breaks down water molecules into oxygen and hydrogen. Light energy is converted into chemical energy. The reduction of carbon dioxide leads to the formation of carbohydrates.
Which event occurs first during photosynthesis?
Absorption of light energy in the form of sunlight by chlorophyll is the first event that takes place. The second event that takes place during the process of photosynthesis is the conversion of light energy into chemical energy where the splitting of water molecules takes place.

What are the events of light reaction in photosynthesis?
During the light-dependent stage (“light” reactions), chlorophyll absorbs light energy, which excites some electrons in the pigment molecules to higher energy levels; these leave the chlorophyll and pass along a series of molecules, generating formation of NADPH (an enzyme) and high-energy ATP molecules.
What are the chemical events in photosynthesis?
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
What are the events that occur during photosynthesis Brainly?
(i) Absorption of light energy by chlorophyll. (ii)Reduction of carbon dioxide to carbohydrates. (iii) Conversion of light energy into chemical energy and splitting of water molecules into hydrogen and oxygen.
What are the three ways of breakdown of glucose?
In aerobic respiration, there are three specific processes, which are glycolysis, Krebs cycle and electron transport chain (oxidative phosphorylation). In this process, the glucose is converted to pyruvate during glycolysis and the same pyruvate produces carbon dioxide and water, along with the generation of energy.
Why is photosynthesis important?
Photosynthesis is important because it produces food for plants and oxygen. Without photosynthesis, it would not be possible to consume many fruits and vegetables necessary for the human diet. Also, many animals that consume humans could not survive without feeding on plants. On the other hand, the oxygen that plants produce is necessary ...
Where does photosynthesis occur?
Chlorophyll is a pigment that is present in the tissues of green plants; Usually photosynthesis occurs in the leaves, specifically in tissue called mesophyll.
What is the meaning of the word "photosynthesis"?
The word photosynthesis is composed of two words: photo and synthesis. Photo means light and synthesis blend. Therefore, this process Literally consists in turning light into food.
What is the energy that is stored in the light phase?
In the light phase is captured light energy that is stored temporarily in the chemical molecules of ATP and NADPH . The ATP will be decomposed to release energy and the NADPH will donate its electrons to convert carbon dioxide molecules into sugars.
Why is the dark phase of a plant called the dark phase?
It is called dark phase because the light is not directly necessary for it to take place. But even though light is not necessary for these reactions to take place, this process requires the ATP and NADPH to be created in the light phase.
How do pigments transfer energy?
In turn, the pigments of photosystems act as a vehicle to channel energy, as they move it to the reaction centers. When light attracts a pigment, it transfers energy to a nearby pigment. This near pigment can also transmit that energy to some other nearby pigment and so the process is repeated successively.
Where do luminous phases begin?
These luminous phases begin in photosystem II. Here, the light energy is used to divide the water.
Why is photosynthesis important?
Updated November 22, 2019. By Laurie Brenner. Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. Without photosynthesis, the carbon cycle could not occur, oxygen-requiring life would not survive and plants would die.
What is the energy used in photosynthesis?
Photosynthesis uses light energy from the sun and carbon dioxide and water in the atmosphere to make food for plants, trees, algae and even some bacteria. It releases oxygen as a byproduct. The chlorophyll in these living organisms, which also contributes to their green hues, absorbs the sunlight and combines it with carbon dioxide to convert these compounds into an organic chemical called adenosine triphosphate (ATP). ATP is crucial in the relationship between energy and living things, and is known as the "energy currency for all life."
How do plants use carbon dioxide?
A plant uses the carbon dioxide exhaled by animals and humans in combination with the sun's energy during cellular respiration to produce the food that it requires. Plants eventually release oxygen back into the atmosphere, resulting in a symbiotic relationship between plants, animals and humans.
Why is cellular respiration important?
Cellular respiration allows all living cells to extract energy in the form of ATP from food and offer that energy for the vital processes of life. All living cells in plants, animals and humans take part in cellular respiration in one form or another. Cellular respiration is a three-step process.
Why is photosynthesis important for all living organisms?
Photosynthesis is important for all living organisms because it provides the oxygen needed by most living creatures for survival on the planet.
Do plants use photosynthesis to produce food?
While most plants use photosynthesis to produce energy, there are some that are non-photosynthetic. Plants that do not use photosynthesis to produce food are usually parasitic, which means they rely on a host for nutrient generation.
