What is the Function of the Plasma Membrane in a Photosynthetic

Question

What is the function of the plasma membrane in a photosynthetic eukaryotic cell?
A) It converts carbon dioxide and water into sugars.
B) It isolates the cell's contents from the external environment.
C) It controls protein synthesis in the cell.
D) It recycles old extracellular material.

Accepted Answer

The plasma membrane (also known as the cell membrane) in a photosynthetic eukaryotic cell serves as a barrier that isolates the cell's contents from the external environment. This allows the cell to maintain the appropriate internal conditions necessary for photosynthesis to occur. Additionally, the plasma membrane regulates the movement of substances in and out of the cell, which is crucial for the cell's survival.
