Question

animal and plant cells
what is the function of the cell membrane?
what is the cell membrane made of? choose three correct answers.
lipids
carbohydrates
cellulose
proteins

Explanation:

The cell membrane is primarily composed of lipids (specifically phospholipids forming a bilayer), proteins (integral and peripheral for transport, signaling, etc.), and carbohydrates (for cell recognition, attached to lipids or proteins as glycolipids or glycoproteins). Cellulose is a component of the plant cell wall, not the cell membrane. So the three correct components are lipids, carbohydrates, and proteins.

Answer:

lipids, carbohydrates, proteins
