Cell organelles

1. Cell Review (pg 6)

2. Nucleus
• Control center, contains DNA

3. Nucleolus
• Region within the nucleus that makes
ribosomes

4. Chromatin
• Long strands of DNA found in the nucleus

5. Nuclear Pore
• Holes in the nuclear membrane. Allows
passage of materials into and out of nucleus

6. Cell Membrane
• Made of a lipid bilayer. Selectively permeable
• Membrane structure (draw)

7. Mitochondria
• Site of cellular respiration. Turns glucose into
energy

8. Golgi Apparatus
• Processes and packages materials for
secretion. The “UPS” of the cell

9. Ribosomes
• Site of protein synthesis

10. Smooth Endoplasmic Reticulum (SER)
• Transports materials throughout cell, makes
lipids, detoxifies poisons

11. Rough Endoplasmic Reticulum (RER)
• Covered with ribosomes. Transports materials
throughout the cell, especially proteins

12. Lysosome
• Cell “stomach”. Contains digestive enzymes
that break down debris, worn out cell parts,
and bacteria

13. Microvilli
• Extensions of the cell membrane. Increase
surface area for secretion and absorption

14. Centrioles
• Form spindle during cell division
