2. Nucleus - Control Center
Contains nearly all of the cell’s DNA
DNA and protein called chromatin
Chromatin coiled in chromosomes
The control center
Either
Prokaryotic-no internal membranes
Eukayrotic-nucleus, organelles
Switch to “cellBioVideodisc – Side A
Show Prokaryotic vs. eukaryotic cells – Frame _______________?

3. Envelope! Nuclear Membrane Pores Two distinct membranes
Envelope!
Pores
Two distinct membranes
Selectively permeable

4. Cytoplasm The area outside the nucleus A “cell” “fluid”
Organelles - specialized functions
Membranes

5. Ribosomes RNA and protein 25 nanometers - small
Site of protein assembly
Pint to the picture of this in the textbook.
The Nucleolus (in the nucleus) is the place where ribosomes are assembled

6. Endoplasmic Reticulum
Similar to nuclear membrane - connected to it
Smooth
Rough with ribosomes
Proteins travel through it

7. Golgi Apparatus
Packages and ships proteins to destinations in the cell
Look in the textbook and find the part of the Goli that is moving.

8. Lysosomes sac-like membrane containing hydrolytic enzymes
fuse with damaged organelles and break them into basic molecules

9. Cytoskeleton cell support structures microtubules microfilaments
movement
proteins attach and move
cilia, flagella use microtubules
Frame 43811

10. Vacuoles Animals: store proteins, fats, carbohydrates
Plants: store water, dissolved salts
support due to turgor pressure

11. Mitochondria Complex organic molecules changed to energy (ATP)
Present in all eukaryotic cells
Inner and outer membranes

12. Chloroplasts
sun’s energy captured
present in plants
Stacked membranes

15. Section Review 3-3 (cont)
23 Eukaryotic cells have a nucleus while prokaryotic cells do not – they have no internal membranes.
24 Plants need chloroplasts to harvest the energy of the sun.
25 Mitochondria are needed to produce energy from chemical fuel.
