Question

Why do plants carry out photosynthesis?

1. To build food molecules for energy and growth 2.to produce carbon dioxide for animals and other organisms
3. to breakdown food molecules for energy and growth
4. to consume carbon dioxide least by animals and organisms

Answer 1

1

Step-by-step explanation

Plants undergo photosynthesis through light reactions and the Calvin-Benson cycle.

In the light reactions, light is absorbed which creates energy that is used in the Calvin cycle.

In the Calvin cycle, plants use energy to turn carbon dioxide into sugars.

Those sugars are then used in the growth of the plant.
