As a cell grows larger and accumulates more contents, will it need more or less cell membrane to survive?

As the plasma membrane grows and accumulates more contents it will require more cell membrane to survive.

Explanation:

Plasma membrane is functionally significant layer that surrounds the cytoplasm of a cell. Plasma membrane performs many important cellular functions. For example transport of specific substance in and out of the cell, contain various protein that act as receptor, the oligosaccharide side chain of the glycoprotein moiety present within the plasma membrane recognizes various bio active compounds.

When a cell grow it increases in size beside increasing its cellular constituents. To surround or protect these cellular constituents more plasma membrane should be need by the cell for its survival.
