1. Organelles
“Tiny Organs”
Ch. 7-2

2. Cytoplasm Jelly-like substance throughout cells.
Contains water and nutrients.

3. Nucleus Largest organelle in eukaryotic cells Contains DNA
Controls all cell’s activities

4. Nucleoplasm Jelly-like substance inside nucleus
Similar to cytoplasm of cell
Surrounds the genetic material and nucleolus
NUCLEOPLASM
nucleolus
Nuclear
envelope
Nuclear
pores

5. Nuclear Membrane (Nuclear Envelope)
Surrounds the nucleus
Controls what gets in/out
Allows things in and out through Nuclear Pores
NUCLEAR
MEMBRANE
NUCLEAR PORES

6. Genetic Material Made of DNA Has directions for making proteins.
chromatin
chromosome

7. Nucleolus
Circular structure inside nucleus
Makes ribosomes
nucleolus

8. Ribosomes Makes proteins according to instructions from DNA Found
Free in cytoplasm
Attached to Rough ER
Attached to nuclear envelope
ribosomes

9. Rough Endoplasmic Reticulum
Usually attached to nuclear envelope
Ribosomes attached to it.
Transports proteins made by ribosomes
Rough ER-
ribosomes attached
Smooth ER-no ribosomes attached

10. Smooth Endoplasmic Reticulum
Manufactures and transports Lipids.
Smooth ER-
NO ribosomes attached

11. Golgi Apparatus (Golgi Bodies)
Packages and ships proteins

12. Lysosomes(animal cells only)
Contains enzymes to breakdown waste.
“Suicide sacs”-recycles waste.

13. Vacuoles Plants: a. Stores water. b. Very large Animals:
a. Stores carbs., lipids, & proteins
b. Small

14. Mitiochondria Makes energy for cell by breaking down glucose.
Very abundant in muscle cells.

15. Chloroplast(plant cells only)
Where Photosynthesis takes place.
Makes glucose
Contains chlorophyll which absorbs sun’s energy and gives plants their green color.

16. Cytoskeleton
Mesh like material throughout cytoplasm.
Supports cell.

17. Centrioles (animal cells only)
Aides in cell division (mitosis)
2 in each cell

18. Cell Membrane Surrounds cell Regulates what comes in and out of cell.
Made of lipids and protein.
CELL MEMBRANE

19. Cell Wall (plant cells only)
Tough outer covering.
Outside of cell membrane
Supports and protects cell.

20. Cillia
Used for movement
Hair-like
Ex: trachea

21. Flagella
Used for movement
Whiplike
Ex: Sperm
