1. Cell Anatomy
Cell Parts & their Function

2. What is a Cell?
A cell is the smallest unit that is
capable of performing life functions.
It is the basic unit of living things.

3. Cell Theory
• All living things are made up of cells.
• Cells are the smallest working units of all
living things.
• All cells come from pre-existing cells through
cell division.

4. Examples of Cells
Amoeba Proteus
Plant Stem
Bacteria
Red Blood Cell
Nerve Cell

5. Cell Organelles
• Cell Parts are referred to as organelles.

6. Cell Wall
Most commonly found in plant cells & bacteria
Supports & protects cells
Cell Wall

7. Cell Membrane
• protective layer around all cells
• allows food and oxygen into the cell and waste products out of
the cell.
Cell Wall
Cell Membrane

8. Cytoplasm
• Gel-like material
• Surrounded by cell membrane
Cell Wall
Cell Membrane
Cytoplasm

9. Nucleus
• contains instructions for everything cell does;
includes DNA

Cytoplasm
Nucleus

10. Ribosome
• Each cell contains thousands
• Make proteins
– (Think of it like a battery plant!)
• Found on ER & floating throughout the cell

11. Endoplasmic Reticulum
(ER for Short)
• Moves materials around in cell
•
•
– (Like a highway)
Smooth type: lacks ribosomes
Rough type : ribosomes embedded in surface

12. Mitochondrion
• releases energy from food
– (Energy Plant)
• Controls level of water and other materials in cell

•
Found only in plant cells.
Contains green chlorophyll
Where photosynthesis takes place
Helps plant cells make food.

• membrane-bound temporary storage spaces
• Contains water solution
• Help plants maintain shape

• Protein 'packaging plant'
• Move materials within the cell
• Move materials out of the cell

16. Make a Cell
• Your assignment:
– We will make a model of the cell using the
materials on the table.
– You must use the paper plate as the basis of your
cell.
