Functions Of Organelles & Cell Structures

Question 1

Cell Surface Membrane

Answer 1

Controls what enters and exits the cell.

Question 2

Cell Wall

Answer 2

Provides support and gives the cell its shape.

In Prokaryotic Cells: Made of murein/peptidoglycon.
In Eukaryotic Plant Cells: Made of cellulose & cell fibres.

Question 3

Slime Wall

Answer 3

Helps the cell escape attack, and adhere to surfaces.
