Question

Why do plant cells have both a cell wall and
cell membrane?

Answer 1

Answer:

Plants have both cell wall and cell membrane because cell membrane prevents outer material to come inside the cell while the cell wall prevents the plant cells from bursting and helps to give the plant the structural support it needs.

Answer 2

Answer:

Plant cells are somewhat unique because unlike animal cells, plant cells contain both a cell wall and cell membrane. ... The cell wall is a protective layer outside the cell membrane that also provides support for the cell's structure.
