Introduction to Photosynthesis

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy, primarily from the sun, which is essential for the process of photosynthesis.

How does light intensity affect the rate of photosynthesis?

Back

An increase in light intensity generally increases the rate of photosynthesis, up to a certain point, after which other factors may become limiting.
