Photosynthesis AP Biology

Front

What is the primary goal of photosynthesis?

Back

The primary goal of photosynthesis is to convert light energy into glucose energy.

Front

What causes photorespiration to occur in plants?

Back

Photorespiration occurs when stomata are closed and CO2 levels are too low.

Front

How do plants obtain CO2 for photosynthesis?

Back

Plants obtain CO2 into the chloroplast by diffusion.

Front

Which type of plant lacks a CO2 storage method?

Back

C3 plants lack a CO2 storage method.

Front

What are CAM plants?

Back

CAM plants are plants that store CO2 at night as an acid in a vacuole.

Front

What is the role of stomata in photosynthesis?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange, including the intake of CO2.

Front

What is the difference between C3 and CAM plants in terms of CO2 fixation?

Back

C3 plants fix CO2 directly during the day, while CAM plants fix CO2 at night.

Front

What is the significance of chloroplasts in photosynthesis?

Back

Chloroplasts are the organelles where photosynthesis occurs, converting light energy into chemical energy.

Front

What is the light-dependent reaction in photosynthesis?

Back

The light-dependent reaction is the first stage of photosynthesis where light energy is converted into ATP and NADPH.

Front

What is the light-independent reaction (Calvin cycle) in photosynthesis?

Back

The light-independent reaction, or Calvin cycle, uses ATP and NADPH to convert CO2 into glucose.
