What is meant by the following statement about the cell membrane?
AysviL [449]

Answer:

The cell membrane is semipermeable because allows only certain molecules to pass through.

Explanation:

Semipermeability is a common property of cell membranes, due to their predominantly lipid composition, which gives them a hydrophobic character.

The cytoplasmic membrane is constituted by a double layer of lipids, in addition to structural proteins and glucides, which prevent the entry of polar or charged molecules. This characteristic allows lipids and small molecules without charge to pass freely through it.

Regarding the other options:

<em>     A. Cell membranes are associated with lysosomes, structures that contain enzymes. However, this characteristic is not related to semipermeability.</em>

<em>     C. They allow the passage of small molecules - devoid of charge - through them.</em>

<em>     D. Not all non-polar molecules pass through, as some need a transporter.</em>
