CAM and C4 plants

Front

What is the main reason C4 plants are more efficient in hot climates compared to C3 plants?

Back

They minimize photorespiration.

Front

In C3 photosynthesis, the reactions that require ATP take place in:

Back

The Calvin cycle only.

Front

What is the enzyme responsible for Carbon Fixation in C3 Photosynthesis?

Back

RuBisCo.

Front

Which of the following is a characteristic feature of CAM plants?

Back

They store CO2 in the form of malate.

Front

What is the primary function of stomata in plant leaves?

Back

Gas exchange.

Front

Define C3 plants.

Back

Plants that use the Calvin cycle for carbon fixation, primarily in moderate climates.

Front

Define C4 plants.

Back

Plants that have adapted to hot, dry environments by minimizing photorespiration and efficiently fixing carbon.

Front

What is photorespiration?

Back

A process where oxygen is taken up and carbon dioxide is released, reducing the efficiency of photosynthesis.

Front

What role does RuBisCo play in photosynthesis?

Back

It catalyzes the first step of carbon fixation in the Calvin cycle.

Front

What is the difference between C3 and C4 photosynthesis?

Back

C3 photosynthesis occurs in moderate climates, while C4 photosynthesis is adapted for hot, dry conditions.
