Photosynthesis Bio Honors

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 main products of photosynthesis?

Back

The main products of photosynthesis are glucose (a sugar) and oxygen.

Front

What role does chlorophyll play in photosynthesis?

Back

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

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 do the light-dependent reactions occur?

Back

The light-dependent reactions occur in the thylakoid membranes of chloroplasts.

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

How does carbon dioxide concentration affect photosynthesis?

Back

Increased carbon dioxide concentration can enhance the rate of photosynthesis, up to a certain point, as it is a key reactant in the process.

Front

Why do CAM plants open their stomata at night?

Back

CAM plants open their stomata at night to collect carbon dioxide, which is then used during the day for photosynthesis, minimizing water loss.

Front

What is the significance of water in photosynthesis?

Back

Water is essential for photosynthesis as it provides electrons and protons for the light-dependent reactions and is a source of oxygen as a byproduct.

Front

What is the role of light in photosynthesis?

Back

Light provides the energy needed to drive the reactions of photosynthesis, particularly in the light-dependent reactions.
