Question
In plants which organelle protects, supports, and provides shape to the cells?
- Mitochondria
- Cytoplasm
- Cell membrane
- Cell wall
Hint:
The cell wall is a thick layer that serves as the cell's defence, structural support, and form.
The correct answer is: Cell wall
- The cell wall provides the cell with support, form, and security.
- It stops the cell from bursting from excessive water absorption.
- Thus, the plant cell wall serves as each cell's cage and as the "skeleton" that supports the structure of the plant as a whole.
