What does the cell membrane do?
1.It separates the cells inside from the outside
2.Allows material to go in and out of a cell
What is the function of the cytoplasm?
Allows chemical reactions to happen
What does rhe Mitocondrian do?
It releases energy from food
Whar does the nucleus do?
It controls the activities of the cells (brain of the cell)
Hiw many parts does a plant cell have and what are they?

Cell wall, Cell membrane,
Sap Vacuole, Mitochondion, Chloroplast, Nucleus, Cytoplasm, Ribosomes
What does the vacuole do?
It stores solutions of sugar and other substances that dissoves in water as cell sap
What does the chloroplast do?
- Contains chlorophyll
- Performs photosynthesis to make food for the plant
What does the cell wall do?
- It gives shape to plant cells
- Strobg and stiff
- Made up of cellulose

What is an organ?
It is a group of different kinds of tissues
What are organ systems?
A group of different organs working together
What do red blood cells do?
To carry oxygen around the body
