Question

The regulation of the flow of material into and outside the cell depends on

• A. cell membrane location
• B. mechanism of osmosis
• C. chemical composition of plasma membrane
• D. plasma membrane permeability

Answer 1

The correct option is D plasma membrane permeability

The plasma membrane of a cell is a semipermeable structure. This means that is selectively permeable to some substances while impermeable to others. Hence, the inflow and outflow of materials and molecules from the cell depends on the permeability of the plasma membrane.

So, the correct answer is 'plasma membrane's permeability'.
