Cell Types

1. Prokaryotic

2. Eukaryotic
Prokaryotic
- -no nucleus
- -DNA= free floating
- -tiny-cell wall and cell membrane
- -flagella
- -tail that allows cell to move
- -no membrane-bound organelles
Eukaryotic
- nucleus
- DNA= in nucleus
- larger
- no flagella
- plant/animal cells
- membrane-bound organelles
Components
- 1. Cell membrane- outside of cell (plasma membrane)
- 2. Nucleus(DNA)- cell's genetic material
- 3. Cytoplasm- between nucleus and cell membrane (cytosol)
Animal Cell
- Circular
- Cell membrane
- Small vacuole
Plant Cell
- rectangular
- cell wall and cell membrane
- 1. Chloroplast
- Chlorophyl - green
- 2. Large central vacuole
- Water
