Question

Which organelle gives plants the ability to grow tall?

chloroplasts
vacuoles
cytoplasm
cell walls
mitochondria

Answer 1

The correct answer is "cell walls"

This is because they are hard and sturdy enabling cells to stack on top of each others without getting separated which in turn increases the plants' overall height.

Answer 2

Answer is cell wall.

Cell wall is a rigid structure which can be seen around the cell membrane of the plant cell. It supplies support and strength to the plant.

Plant grows towards the light. Hence, the cells in the plant should have much strength to hold the plant without falling down. This strength is provided from the cell walls of the plant cells.
