Question

cellular boundaries

1. prokaryotes have a strong supporting layer around the membrane known as the
2. the regulates what enters and leaves the cell.
3. the membrane is selectively ; some substances can pass, others cannot.
4. what can form channels and pumps to move material across the membrane?
5. what acts as chemical identification cards?

Explanation:

26.

Prokaryotes (like bacteria) have a cell wall outside the cell membrane that provides structural support and protection.

The cell membrane (plasma membrane) is a selectively permeable barrier that controls the movement of substances into and out of the cell.

The cell membrane is selectively permeable, meaning it allows certain substances to pass through while preventing others from doing so, based on factors like size, charge, and solubility.

Answer:

cell wall
