what are step of photosynthesis?

It is convenient to divide the photosynthetic process in plants into four stages, each occurring in a defined area of the chloroplast: (1) absorption of light, (2) electron transport leading to the reduction of NADP+ to NADPH, (3) generation of ATP, and (4) conversion of CO2 into carbohydrates (carbon fixation).

['The photosynthesis chemical equation states that the reactants (carbon dioxide, water and sunlight), yield two products, glucose and oxygen gas.', 'The single chemical equation represents the overall process of photosynthesis.']

The first stage of photosynthesis is called the light reactions. During this stage, light is absorbed and transformed to chemical energy in the bonds of NADPH and ATP.

To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.

Photosynthesis is the process by which plants and some bacteria and protists synthesize sugar molecules from carbon dioxide, water, and sunlight. ... During the light reactions, an electron is stripped from a water molecule freeing the oxygen and hydrogen atoms.

The process of photosynthesis is considered as an oxidation-reduction reaction activated by light absorbed by chlorophyll or certain other substances (e.g., phycocyanin, fucoxanthol), resulting in the evolution of oxygen from water and in the formation of reduced carbon compounds (e.g., carbohydrate) from carbon ...

Photosynthesis is the conversion of light energy into chemical energy by living organisms. The raw materials are carbon dioxide and water; the energy source is sunlight; and the end-products are oxygen and (energy rich) carbohydrates, for example sucrose and starch.

Main Structures and Summary of Photosynthesis Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose.

Explanation: In order for plants to carry out the process of photosynthesis, they need water, carbon dioxide and light. The water and carbon dioxide are the reactants - materials present before the chemical change. During the light reaction, chlorophyll molecules absorb light energy which is used to split water.

The process of photosynthesis Photosynthesis takes place in the part of the plant cell containing chloroplasts, these are small structures that contain chlorophyll. 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).

Photosynthesis is the process by which green plants, algae, and cyanobacteria convert solar energy into chemical energy. They are termed as producers or autotrophs.

The Two Parts of Photosynthesis Photosynthesis takes place in two stages: the light-dependent reactions and the Calvin cycle. In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water.

Glucose and oxygen are the final products of photosynthesis.

The Calvin cycle is part of photosynthesis, which occurs in two stages. In the first stage, chemical reactions use energy from light to produce ATP and NADPH. In the second stage (Calvin cycle or dark reactions), carbon dioxide and water are converted into organic molecules, such as glucose.

Photosynthesis takes water and carbon dioxide and turns into glucose sugar. To do this the cell must capture energy from the sun to change the chemical bonds. Respiration takes the sugar produced by the process of photosynthesis and "burns" it using oxygen to produce energy in the form of ATP.

Photosynthesis is the process plants use to convert energy from the sun into usable energy for their cells. Plants use the light energy of the sun, carbon dioxide, and water to make glucose (a sugar), and oxygen. The energy of the sun is captured and stored in the bonds between atoms in glucose molecules.
