Question

Plants where light-independent reactions take place in bundle sheath cells (different cells than where light-dependent reactions occur) are using what kind of photosynthesis?

Answer 1

Answer:

C4 type of photosynthesis

Explanation:

The process of photosynthesis takes place in two phases: the light-dependent phase and light-independent phase ( Calvin cycle).

The RUBISCO enzyme which catalyses the reaction of Calvin cycle has the binding affinity for both carbon dioxide and oxygen. When the enzyme binds to the oxygen results in the loss of ATP through a process called photorespiration.

To reduce the effect of photorespiration, some plants have made morphological adaptations in the chloroplast by separating the site of light-dependent phase and light-independent phase.

The light-dependent phase takes place in the mesophyll cells while the Calvin cycle takes place in the bundle sheath cell surrounding the leaf veins. These plants are known as C4 plants.

Thus, the C4 type of photosynthesis is the correct answer.
