The Reactions of Photosynthesis…Finally
- Light reactions occur in the thylakoid membrane Inputs: water (H 2 O) and light Outputs: Oxygen (O 2) and energy (ATP and NADPH)
- Light-independent reactions occur in the stroma Inputs: ATP and NADPH (from the light reactions) and CO 2 Outputs: carbohydrates
What are the three things needed for photosynthesis?
What are the three things needed for photosynthesis?
- Light intensity. Without light, plants cannot photosynthesize, even if there is enough water and carbon dioxide in the environment.
- Carbon dioxide concentration. Carbon dioxide is a necessary reagent for the process to occur.
- Amount of chlorophyll. ...
- Water. ...
- Temperature. ...
- Minerals and nutrients. ...
What is the final product of photosynthesis?
The products and reactants for photosynthesis are reversed in cellular respiration: The reactants of photosynthesis are carbon dioxide and water, which are the products of cellular respiration.
What two things are produced by photosynthesis?
The oxygen and water produced in photosynthesis exit through the stomata. 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.
What is the overall process of photosynthesis?
Photosynthesis is the process in which plants make glucose from luminous energy, water and carbon dioxide. The luminous energy derives from the sun, which is constantly subjected to nuclear fusion (using hydrogen) and is absorbed by the Palisade cells, which are optimized for energy absorption.
What are the 3 inputs of photosynthesis?
To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis. Carbon dioxide enters through tiny holes in a plant's leaves, flowers, branches, stems, and roots. Plants also require water to make their food.
What are the two inputs of photosynthesis?

What is the most important input in photosynthesis?
The inputs of photosynthesis are in the form of both matter and energy. The matter needed for the inputs of photosynthesis is carbon dioxide, and the energy used as an input is sunlight. These two reactants are considered the inputs for photosynthesis because they are needed to start the process.
What are the 2 stages of photosynthesis?
While there are many steps behind the process of photosynthesis, it can be broken down into two major stages: light-dependent reactions and light-independent reactions.
What 2 main products are outputs of photosynthesis?
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.
What is the process of photosynthesis?
Most life on Earth depends on photosynthesis .The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O 2) and chemical energy stored in glucose (a sugar).
What is the chemical used in photosynthesis?
ATP. Noun. (adenosine triphosphate) chemical found in most living cells and used for energy. C3 photosynthesis. Noun. Used by the majority of plants, it involves producing a three-carbon compound called 3-phosphoglyceric acid during the Calvin Cycle, which goes on to become a sugar called glucose. C4 photosynthesis.
How does carbon dioxide change water into glucose?
Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.
What is the energy that plants use?
Inside the plant cell are small organelles called chloroplasts, which store the energy of sunlight. Within the thylakoid membranes of the chloroplast is a light-absorbing pigment called chlorophyll, which is responsible for giving the plant its green color. During photosynthesis, chlorophyll absorbs energy from blue- and red-light waves, and reflects green-light waves, making the plant appear green.
Why are the leaves of plants green?
The plant leaves are green because that color is the part of sunlight reflected by a pigment in the leaves called chlorophyll. Photograph courtesy of Shutterstock. ATP.
What is the chemical element that forms the basis of all known life?
series of reactions that take place during photosynthesis, where carbon dioxide and water from the atmosphere are converted into sugar. carbon. Noun. chemical element with the symbol C, which forms the basis of all known life.
Where does the light dependent reaction take place?
The light-dependent reaction takes place within the thylakoid membrane and requires a steady stream of sunlight, hence the name light- dependent reaction. The chlorophyll absorbs energy from the light waves, which is converted into chemical energy in the form of the molecules ATP and NADPH.
