Question

1. what is the role of the cell membrane in maintaining homeostasis? a. it synthesizes proteins necessary for cellular function. b. it controls the entry and exit of substances, maintaining the internal balance of the cell. c. it provides energy for cellular activities. d. it stores genetic material for cell division.

Explanation:

The cell - membrane is a selectively permeable barrier. It controls the movement of substances in and out of the cell, which helps maintain the internal balance (homeostasis) of the cell. Protein synthesis occurs in ribosomes, energy for cellular activities is mainly provided by mitochondria, and genetic material is stored in the nucleus.

Answer:

b. It controls the entry and exit of substances, maintaining the internal balance of the cell.
