Overview

Photosynthesis is an anabolic process in green plants in which food is prepared from carbon dioxide and water in the presence of sunlight and chlorophyll. Leaves are the main photosynthetic organ. The process also releases oxygen into the atmosphere and helps maintain the balance of carbon dioxide a

Key Concepts

Photosynthesis is the process by

Photosynthesis is the process by which green plants prepare glucose from carbon dioxide and water using sunlight and chlorophyll. The overall equation

Leaves are the main organs

Leaves are the main organs of photosynthesis. Their flat and thin shape gives a large surface for light absorption, and their venation helps in the tr

Chloroplasts are biconvex disc

Chloroplasts are biconvex disc-like organelles surrounded by a double unit membrane. Their inner aqueous matrix is called stroma. The stroma contains

Chlorophyll is the most important photosynthetic

Chlorophyll is the most important photosynthetic pigment. It has a magnesium-containing head and a phytol tail. Chlorophyll a and chlorophyll b are fo

Stomata are openings controlled by two

Stomata are openings controlled by two kidney-shaped guard cells with thick inner walls and chloroplasts. During the day, high glucose in guard cells
