1 CELL pp

2 LEVELS OF ORGANIZATION

3 HISTORY Hooke: observed cork

4 Leeuwenhoek: first to observe living cells

5 CELL THEORY All living things composed of cells.
Cells are basic units of structure and function. Cells come from pre-existing cells

6 BASIC PARTS OF A CELL Cell membrane Genetic material (DNA)
Ribosomes: make proteins Cytoplasm: surrounds the cell’s organelles

7 Cell membrane Selectively permeable: controls what comes into and out of the cell Made of phospholipids that form a lipid bilayer

8

9 Cell membrane has proteins
peripheral: attached to the surface integral: embedded in the bilayer

10 Fluid mosaic model: cell membrane behaves more like a fluid than solid

11

12 CELL TYPES Prokaryotic: oldest living cells that lack membrane-bound organelles and are unicellular Eukaryotic: contain a membrane-bound nucleus and organelles

13 Prokaryotic Cell Prokaryotic

14 Animal Cell

15 Plant Cell

16

17 Plant cells similar to animal cells since both are eukaryotic
Plants also have: A cell wall Chloroplasts: organelles that undergo photosynthesis Large vacuole: stores water
