valina [46]

The structure of the plasma membrane makes this type of transport necessary for fluids is discussed below:

<h3>What do you mean by phospholipid membrane?</h3>

The membrane that divides the interior of the cell from the external environment is known as the plasma membrane, sometimes known as the cell membrane, and is present in all cells. A cell wall is affixed to the plasma membrane on the exterior of bacterial and plant cells.

Why does the structure of the plasma membrane make this type of transport necessary for fluids
