HB: Photosynthesis Review 2024 - 2025

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.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light reactions and the Calvin cycle (light-independent reactions).

Front

Where do light reactions occur in the plant cell?

Back

Light reactions occur in the thylakoid membranes of the chloroplasts.

Front

What is the primary function of the light reactions?

Back

The primary function of the light reactions is to convert light energy into chemical energy in the form of ATP and NADPH.

Front

What is produced during the light reactions?

Back

The light reactions produce ATP, NADPH, and oxygen as a byproduct.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment that absorbs light energy, primarily in the blue and red wavelengths, and plays a crucial role in the light reactions of photosynthesis.

Front

What is the Calvin cycle?

Back

The Calvin cycle is the set of light-independent reactions in photosynthesis that convert carbon dioxide and other compounds into glucose.

Front

What are the inputs of photosynthesis?

Back

The inputs of photosynthesis are carbon dioxide (CO2), water (H2O), and light energy.

Front

What are the outputs of photosynthesis?

Back

The outputs of photosynthesis are glucose (C6H12O6) and oxygen (O2).

Front

How does carbon dioxide enter the plant?

Back

Carbon dioxide enters the plant through small openings called stomata, located on the leaves.
