Photosynthesis is a process in which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy stored in glucose molecules. This process involves several steps:
-
Absorption of light: Chlorophyll, a green pigment in plant cells, absorbs sunlight.
-
Water uptake: Plants take in water from the soil through their roots and transport it to the chloroplasts in their cells.
-
Carbon dioxide uptake: Plants also take in carbon dioxide from the air through small openings in their leaves called stomata.
-
Conversion of light energy: In the chloroplasts, light energy is used to convert water and carbon dioxide into oxygen and glucose.
-
Production of glucose: Glucose, a sugar molecule, is formed during this process and serves as a source of energy for the plant.
-
Release of oxygen: Oxygen is released as a byproduct of photosynthesis and is essential for many living organisms.
Overall, photosynthesis is a vital process that provides energy for plants and produces oxygen, which is crucial for supporting life on Earth.
