1. The
Microscope
Do you know the parts?

2. What is a Cell????
The Cell Theory
1) All organisms are made of cells.
2) Cells are the basic unit of structure.
3) New cells come from preexisting cells.

3. Diversity of Cell Life
All organisms fit into 2 groups:
1) unicellular- one-celled organisms
2) multicellular- many celled organism
- cell differentiation/specialization
- each cell has a specific function
ex.- blood cells, muscle cells, nerve cells

4. Cell Differentiation/Specialization

5. Levels of Multicellular Organization 1) Cell
2) Tissue- similar cells working together
3) Organ- similar tissues working together
4) Organ System- groups of organs working together
Digestive System
Stomach Cell

6. Cell Types
1) Prokaryotes
- no nucleus
- few organelles (cell parts)
- smaller, less complex
ex.- Bacteria

7. 2) Eukaryotes - have a nucleus - many organelles
- larger, more complex
Examples:
Plant
Protist
Fungi
Animal

8. CELL ORGANELLES Nucleus - controls cell’s processes - contains DNA
Ribosomes
- assembles amino acids into proteins
Vacuoles
- stores materials for the cell

9. Mitochondria (powerhouse)
provides energy for the cell
Chloroplast (plants/algae)
carries out photosynthesis
Cell Membrane
allows materials to move in/out of cell
Cell Wall (plants, fungi, bacteria)
provide extra protection

11. Plant and Animal Cell Differences
Plant Cell Animal Cell
Contains: Cell Wall No Cell Wall
Chloroplast No Chloroplast
Large Vacuole Small Vacuole
Shape: Square, rigid Round, fluid
