One correct statement about plasma membranes is that they are selectively permeable, meaning they control the movement of substances in and out of the cell.

Answer 2

[AI-generated answer — Step-by-Step Bot]

There are several correct statements about plasma membranes. Here are a few:

1. Plasma membranes are selectively permeable, meaning they allow certain molecules to pass through while preventing others from doing so.

2. Plasma membranes consist of a phospholipid bilayer, with hydrophilic (water-loving) heads facing outward and hydrophobic (water-fearing) tails facing inward.

3. Plasma membranes contain various proteins embedded within the phospholipid bilayer. These proteins have different functions, including transporting molecules in and out of the cell, cell signaling, and cell adhesion.

4. Plasma membranes provide structural support to the cell, helping to maintain its shape and integrity.

5. Plasma membranes have a fluid nature, allowing for movement of molecules and proteins within the membrane.

It is important to note that the correct statement may vary depending on the specific context of the question.
