You explored the cell during the webquest
2
Now we will discuss a few of the more common cell organelles

Vocabulary:
organelles
Parts of a cell that do different jobs in the cell
4
1. Can find in both plant and animal cells
2. Gives support and protection to the cell
3. Controls entry in and out of the cell
Cell Membrane

Vocabulary:
Cell membrane
A part of the cell that controls entry in and out of the cell
Nucleus
6
1. Large and oval in appearance
2. Controls cell activity
3. The brain (or boss)
7
Vocabulary:
nucleus

9
Vocabulary:
cytoplasm
A part of the cell that supports and protects organelles
Endoplasmic Reticulum
10
1. Network of tubes or membrane
