The volume enclosed by the plasma membrane of plant cells is often much larger than the corresponding volume in animal cells. the most reasonable explanation for this observation is that a) plant cells are capable of having a much higher surface-to-volume ratio than animal cells. b) plant cells have a much more highly convoluted (folded) plasma membrane than animal cells. c) plant cells contain a large vacuole that reduces the volume of the cytoplasm. d) animal cells are spherical, whereas plant cells are elongated.

The correct answer is option C.

Explanation:

The plant cells comprise a large vacuole, which minimizes the volume of the cytoplasm. The vacuoles refer to the storage bubbles witnessed in the cells, they are found in both plant and animal cells, however, they are much bigger in the cells of the plants.  

The vacuoles in the plant cells are much bigger in comparison to the animal cells. These vacuoles can at certain occasions fill more than half of the volume of the cell. This is the reason that the volume enclosed by the plant cells' plasma membrane is generally much larger in comparison to the volume in animal cells.  

the answer is :

looks like the answer is     c     to me!
