List the function of each organelle
• GREEN TEST• Nucleus
• Endoplasmic reticulum
• Cell membrane
• RED TEST• mitochondria
• Vacuole
• Cell wall
Things to find out about cells
1. What shape do most cells have?
2. How many nuclear membrane layers? Why?
3. What produces energy in a cell?
4. How does water get into a cell?
5. How does CO2 get out of a cell?
6. What does a nucleus do?
7. What does the endoplasmic reticulum do? Look like?

Two Types of Cells
• Prokaryotic• “simple”• no nucleus or
membrane bound organelles
• most have cell wall• All are bacteria of
some type
• Eukaryotic• Have nucleus* and
membrane bound organelles
• More diverse• Only plant and fungi
have cell walls
Generalized Bacteria Cell
List of Organelles w/ MembranesCell Membrane:
Nucleus:
nucleolus
Mitochondria:
Chloroplast:
Vacuole:
Cell membrane
Cytomembrane Organelles
• Endoplasmic Reticulum (ER):– rough– smooth
• Golgi Body:
• Lysosomes/peroxisomes:
Generalized cell for cytomembrane system
Other Organelles
• Ribosomes
• Centrioles
• Cytoskeleton– microtubules– microfilaments
Other Organelles, cont
• Cytoplasm/cytosol
• Cell wall– slime capsule
• Cilia/flagella

How substances enter cell (ch 5)
• W/out nrg = Passive• Osmosis:
• Diffusion:
• Facilitated Diffusion:
• With energy• Active transport:
• Bulk transport:– endocytosis
– exocytosis
