Question

Level 1 Q2 What structure is found outside the cell membrane of a plant cell that gives the cell its strength and shape?  Group of answer choices: rough ER , cytoskeleton, cell wall, or smooth ER

Answer 1

The cell wall is the structure outside the cell membrane of a plant cell that provides strength and shape. It is made mainly of cellulose, which makes the cell rigid and protective.

Step-by-step explanation:

The structure found outside the cell membrane of a plant cell that gives the cell its strength and shape is the cell wall. The cell wall is a rigid covering that protects the cell, provides structural support, and gives shape to the cell. While prokaryotic cell walls mainly comprise peptidoglycan, plant cell walls are primarily made up of cellulose, a polysaccharide consisting of glucose units. This component is why, for example, when you bite into a raw vegetable like celery, it crunches; you're tearing through the rigid cell walls.
