1 Cells

2 How do we study cells? Light Microscope: Magnify about 1000 times Electron Microscope: uses electron beams and magnifies 1,000,000 times. Used to view individual organelles Ultracentrifuge: uses gravity to separate organelles by size. This is called cell fractionation.

4 Why cells are small? As things increase in volume the surface area to volume ratio decreases. Larger objects have less surface area to get the amount of nutrients they need from the environment

5 Organelles and their Function Nucleus

6 Organelles and their Function Ribosome

7 Organelles and their Function Endoplasmic Reticulum

8 Organelles and their Function Golgi Apparatus

9 Organelles and their Function Lysosome

10 Organelles and their Function Vacuoles

11 Organelles and their Function Mitochondria

12 Organelles and their Function Chloroplast

13 Organelles and their Function Peroxisome

14 Organelles and their Function Cell Membrane

18 Types of Cells Prokaryotic vs Eukaryotic. –Prokaryotic cells are the cells of bacteria –Eukaryotic cells are the cells that make up all other organisms Plants vs. Animal

19 Prokaryotic Cells Have no nucleus, instead its DNA is stored in the nucleoid region. Only has a cytoplasm, ribosomes, and a cell membrane.
