Question

how does the cell membrane help to maintain the health of this cell?
a by providing support and structure for the cell
b by regulating the transport of materials in and out of the cell
c by manufacturing protein to provide energy for the cell
d by storing food as future energy for the cell

Explanation:

The cell membrane is a selectively permeable barrier. It controls what enters and exits the cell, which is crucial for maintaining the cell's internal environment (homeostasis). Option A is incorrect as the cell wall provides support and structure. Option C is wrong because ribosomes manufacture proteins, and mitochondria (not the cell membrane) are related to energy production. Option D is incorrect as storage of food (e.g., in vacuoles) is not the cell membrane's function.

Answer:

B. By regulating the transport of materials in and out of the cell
