Molls Photosynthesis Review

What is photosynthesis?

Back

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

Front

What are the main products of photosynthesis?

Back

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

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in chloroplasts that absorbs light energy, primarily from the blue and red wavelengths, to drive the photosynthesis process.

Front

What are the two main stages of photosynthesis?

Back

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

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is the light-dependent reaction?

Back

The light-dependent reaction is the first stage of photosynthesis that converts solar energy into chemical energy in the form of ATP and NADPH, releasing oxygen as a byproduct.

Front

What is the Calvin cycle?

Back

The Calvin cycle, also known as the light-independent reactions, is the second stage of photosynthesis where ATP and NADPH are used to convert carbon dioxide into glucose.

Front

What is the significance of water in photosynthesis?

Back

Water is essential in photosynthesis as it provides electrons and protons for the light-dependent reactions and is split to release oxygen.

Front

What is the chemical equation for photosynthesis?

Back

The chemical equation for photosynthesis is 6CO2 + 6H2O -> C6H12O6 + 6O2.

Front

How does carbon dioxide enter the plant?

Back

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