1. Cell Organelles

2. CELL WALL
Provide support & protection
Made of cellulose
Not present in animal cells

3. Pair of organelles found in animal cells only
CENTRIOLE
Pair of organelles found in animal cells only
aid in cell division

4. CHLOROPLAST
Site of photosynthesis
Filled with chlorophyll (green pigment)
Plant cells only

5. CYTOSKELETON
As name implies provides framework for cell
Made of microtubules & microfilaments

6. ENDOPLASMIC RETICULUM (ER)
Can be ROUGH (with ribosomes attached) or SMOOTH (w/o ribosomes)
Serves as transport within a cell
“Conveyor belt”

7. GOLGI APPARATUS or BODIES
Package and sort proteins and get them ready for export/shipping out of the cell
“post office”

8. LYSOSOME Contains STRONG digestive enzymes
Gets rid of waste, bacteria, worn-out organelles
Animal cells usually

9. MITOCHONDRIA The “powerhouse” of the cell Site of cellular respiration
Sugar is burned to give energy

10. NUCLEUS The “brain” of the cell
Directs all cell activities - control center
Contains the genetic material

11. NUCLEOLUS
Smaller body found inside the nucleus – THE BLUE PART
Directs the production of RNA

12. NUCLEAR ENVELOPE or MEMBRANE
Surrounds the nucleus and controls what enters and leaves through the nuclear pores
The YELLOW outside part

13. This is the DNA (in its unwound state)
CHROMATIN
This is the DNA (in its unwound state)
The RED squiggly stuff

14. CYTOPLASM
“jelly-like” fluid found within the cell in which all organelles are floating in

15. CELL or PLASMA MEMBRANE
Selectively permeable – controls what enters and leaves the cell

16. RIBOSOME
Tiny knob-like organelles that are the site of protein synthesis
Found on ER or floating freely in cytoplasm

17. VACUOLE
Warehouse and storeroom for cell
Store water, food, waste, etc
Large, central one in plants!
