1. Cells: The Building Bricks of Life

2. Robert Hooke
Used a “microscope” / magnifying glass to look at cork
From England
Discovered what a cell was
by looking at a piece of cork

3. Anot Van Leeuwenhook
Dutch inventor who created the microscope that we recognize today
First person to discover a single celled protozoa
Protozoa is like
pond scum
He also looked
at blood cells

4. Cell
The smallest unit of life that can perform all life processes.

5. Cell Theory All organisms are made of one or more cells
The cell is the basic unit of all living things
All cells come from existing cells

6. Types of Cells Prokaryotic Cells Bacteria Cells Plant Animal
Eukaryotic Cells
Plant
Animal
Fungi

7. Prokaryotic Cell Example: bacteria DOES NOT have a nucleus.
DOES NOT have organelles
Comes in different shapes and sizes.

8. Eukaryotic Cell Example: plant, animal, and fungi HAS a nucleus
HAS organelles
Is usually 10
times larger than
Prokaryote cells.

9. Cell Organelles
Cell Parts are referred to as organelles.

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

11. 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

12. Cytoplasm Gel-like material Surrounded by cell membrane Cell Wall

13. Nucleus contains instructions for everything cell does; includes DNA

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

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

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

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

Contains water solution
Help plants maintain shape

Move materials out of the cell
