NADPH and ATP.

Front

Define photosynthesis.

Back

The process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What role does chlorophyll play in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily from the sun, which is essential for the photosynthesis process.

Front

What is the Calvin cycle?

Back

A series of biochemical reactions that take place in the chloroplasts of photosynthetic organisms, converting carbon dioxide and other compounds into glucose.

Front

What is the significance of oxygen in photosynthesis?

Back

Oxygen is a byproduct of photosynthesis and is essential for the respiration of most living organisms.

Front

How does carbon dioxide enter the plant for photosynthesis?

Back

Carbon dioxide enters the plant through small openings called stomata.
