1
Q
What is the Definition of a Cell?
A
The Smallest Unit of Life that can Replicate Independently
2
Q
What is the Function of the Cell Membrane?
A
To control which substances can pass in and out of the cell.
3
Q
What is the Function of the Nucleus?
A
- Contains the genetic material / DNA.
- Controls the activities of the cell.
4
Q
What is the Function of the Cytoplasm?
A
- Gel-like substance where all of the sub/cellular structures sit in.
- Where chemical reactions take place.
5
Q
What is the Function of the Mitochondria?
A
- Provide cells with the energy they need to function.
- Break down sugars in aerobic respiration.
6
Q
What is the Function of Ribosomes?
A
- Site of Protein Synthesis.

- Permanent Vacuole
- Chloroplasts
8
Q
What is the Function of the Cell Wall?
A
- Made from cellulose.
- Provides support and structure to the cell.
9
Q
