Plzzzzzzz zzzzzzzz mark as brainliest please plzzzzzzz zzzzzzzz .... Thanks...

Explanation:

Answer 2

A) Bundle sheath cells

B) Bundle sheath cells

C)  Mesophyll cells

D) Mesophyll cells.

Explanation:

• In the given question, the steps of photosynthesis are discussed of the C4 plants.
• The C4 plants undergo C4 type of photosynthesis that is the first 4 carbon product formed in the pathway is oxaloacetate.
• The C4 plants like sugarcane have the advantage that the photosynthesis takes place in the different cells that are the mesophyll cell and the bundle sheath cell.
• The reaction which takes place in the mesophyll cell is the conversion of carbon dioxide with PEP carboxylase to oxaloacetate, a 4-C product.
• The oxaloacetate then enters the bundle sheath cells where the oxaloacetate is converted to the carbon dioxide and the steps of the Calvin cycle is performed that is carboxylation, reduction and regeneration.
