Root Hair Cell

1) What are the organelles found in the cell?

Nucleus, cytoplasm, cell membrane, cell wall, and vacuole.

2) What are the functions of these organelles?

Nucleus: Stores DNA which Is the cell, controls all cell activities

Cytoplasm: Place where cellular activities take place.

Cell membrane:It has selective permeable membrane, which controls the movement of substances in and out of the cell

Cell Wall: Give the plant its shape and is a fully permeable structure

Vacuole: Provides structural support and maintain turgor pressure.

3) Why are these functions of the organelles important to the living cell?

Without the nucleus, the cell cannot function.

Without the cytoplasm, cellular activities cannot take place.

Without the cell membrane, anything can enter the cell and it might get too turgid.

Without the cell wall, the plant does not get its shape.

Without the vacuole, the plant cannot maintain turgor pressure.
