Biology I: Structure and function (cells to systems)

Question 1 of 30

Time left: 00:00

Cells and organelles (trick: location vs function):

A student says: "The cell membrane is the part that controls what enters and leaves, so it must be the same as the cell wall in plant cells."

Which statement best corrects the student's idea?

Select one option.

The cell wall controls what enters and leaves; the cell membrane only supports the cell.
Plant cells have both a cell membrane and a cell wall; the membrane controls entry/exit and the wall mainly provides support.
Only animal cells have a cell membrane; plant cells use a cell wall instead.
The cell membrane is found only in plant cells; the cell wall is found only in animal cells.
The cell wall makes energy; the cell membrane stores DNA.
