1. Section 1.2: Microscopes allow us to see inside the cell

2. Cells are divided into two categories
Eukaryotic cell – cell with a nucleus, that contains genetic material (DNA)
-eukaryotic cells have:
organelles
- parts of a cell that perform specific functions (jobs)
Prokaryotic cell – cell without a nucleus, genetic material (DNA) is in the cytoplasm

3. Eukaryotic Cell
Prokaryotic Cell

4. Cells are diverse cytoplasm - “jellylike” material inside cell
- holds everything in place
- “Jell-O Mold”

5. Plant Cell
cytoplasm

6. Cells are diverse Eukaryotic cells have: organelles - parts of a cell
cytoplasm
- “jellylike” material inside cell
cell membrane
- covering that controls entry/exit
“The Traffic Cop”
