Question

What is the main adaptive advantage of the C4 and CAM photosynthesis strategies over C3 photosynthesis?

a.They make it possible for the plant to use the Calvin cycle during the day.
b.They allow the plant to synthesize glucose without CO2.
c.They allow the plant to hold its breath and still perform photosynthesis.
d.They allow the plant to synthesize glucose under hot conditions.

Answer 1

D. They allow the plant to synthesize glucose under hot conditions.

Step-by-step explanation:

C4 and CAM photosynthesis strategies allow for plants to produce glucose in hot and dry conditions.

Plants such as cacti, which live in hot conditions, have the advantage from their C4 and CAM systems.

In contrast to C3 photosynthesis, C4 and CAM systems allow plants to get more CO2 from the air and help them conserve water.

This then allows them to efficiently create glucose with the CO2.

So, the correct answer is D.

Answer 2

D. they allow the plant to synthesize glucose under hot conditions.
