Question

Cell membranes are described as selectively permeable. Four students were asked to

explain what this means and provided the answers given below.
Student 1: Cell membranes prevent all materials from entering the cell.
Student 2: Cell membranes only provide structural support for the cell.
Student 3: Cell membranes regulate which substances can enter and exit the cell.
Student 4: Cell membranes allow water and water-soluble substances to enter the cell.
Which student correctly.identified the function of the selectively permeable membrane?
Student 1
Finish
Student 2
Student 3

Answer 1

Student 3 correctly identified the function of the selectively permeable membrane.

Step-by-step explanation:

The student who correctly identified the function of the selectively permeable membrane is Student 3. Cell membranes are described as selectively permeable because they regulate which substances can enter and exit the cell. This means that certain molecules and ions can pass through the cell membrane while others are restricted.
