Photosynthesis is the process by which plants, some bacteria and some protistans use the energy from sunlight to produce glucose from carbon dioxide and water. This glucose can be converted into pyruvate which releases adenosine triphosphate (ATP) by cellular respiration. Oxygen is also formed.
Sugar made in the chloroplasts supplies the entire plant with chemical energy AND with carbon skeletons to synthesize all the major organic molecules of cells - Carbohydrate (as disaccharide sucrose) travels via the veins to nonphotosynthetic cells
3 sie 2023 · Photosynthesis is defined as the process, utilized by green plants and photosynthetic bacteria, where electromagnetic radiation is converted into chemical energy and uses light energy to convert carbon dioxide and water into carbohydrates and oxygen.
Photosynthesis is not just a simple process of oxygen production. It is an elegantly complex process that combines carbon dioxide, water, and energy from sunlight to produce food for green plants in the form of water, oxygen, and a single-sugar molecule called glucose.
Plants, algae, and phytoplankton absorb sunlight, take in carbon dioxide from the atmosphere and water from their environment, release oxygen back into the atmosphere, and produce glucose. This is the chemical process of photosynthesis. Photosynthetic organisms use sunlight and water to convert carbon dioxide into glucose molecules.
The Light-Dependent Reactions: Generating ATP and NADPH. Photosynthesis begins with these reactions, which occur in thylakoid membranes. Photosystems are clusters of proteins and chlorophyll in thylakoid membranes. High-energy electrons form when pigments in photosystem II absorb light.
Photosynthesis can be summarised by the word equation: Energy from the Sun. Carbon dioxide + Water Glucose + Oxygen. Plants absorb water through their roots and carbon dioxide through the stomata (pores) in their leaves. Guard cells control the movement of gases in and out of leaves.
