Question

The small size of cells relates to the need to exchange materials across the plasma membrane. The microscopic size of most cells provides a large surface-to-volume ratio. The plasma membrane is a phospholipid bilayer with embedded proteins.-------

Answer 1

Cells' small size allows efficient exchange of materials across the plasma membrane due to a large surface-to-volume ratio. The plasma membrane, composed of a phospholipid bilayer with embedded proteins, regulates the movement of substances in and out of the cell.

Step-by-step explanation:

The small size of cells relates to the need to exchange materials across the plasma membrane.

The microscopic size of most cells provides a large surface-to-volume ratio, which allows for efficient exchange of nutrients and waste products.

The plasma membrane, which is composed of a phospholipid bilayer with embedded proteins, controls the movement of substances in and out of the cell.
