1. 3.2 Cell Organelles
The cytoskeleton gives eukaryotic cells an internal structure and organization.
The cytoskeleton has many functions.
supports and shapes cell
helps position and transport organelles
provides strength
assists in cell division
aids in cell movement

2. 3.2 Cell Organelles
The nucleus stores genetic information.

3. 3.2 Cell Organelles Many processes occur in the endoplasmic reticulum.
There are two types of endoplasmic reticulum.
rough endoplasmic reticulum
smooth endoplasmic reticulum

4. 3.2 Cell Organelles
Ribosomes link amino acids to form proteins.

5. 3.2 Cell Organelles
Vesicles are membrane-bound sacs that hold materials.

6. 3.2 Cell Organelles
Mitochondria supply energy to the cell.

7. 3.2 Cell Organelles
Vacuoles are fluid-filled sacs that hold materials.

8. 3.2 Cell Organelles
Lysosomes contain enzymes to digest material.

9. 3.2 Cell Organelles Centrioles are tubes found in the centrosomes.
Centrioles help divide DNA.
Centrioles form cilia and flagella.

10. 3.2 Cell Organelles
Plant cells have organelles that uniquely suit their needs.
A cell wall provides rigid support.

11. 3.2 Cell Organelles
Chloroplasts convert solar energy to chemical energy.
