3. All About Cells!

4. Big Idea:
Cells are the building blocks of life. They are the smallest thing that is considered ALIVE.

5. Let’s Review Cell Theory:
All living things are made up of at least 1 cell.
Cells are the smallest working units of all living things.
All cells come from other cells.

6. 2 Main Types of Cells Basic, single-celled organisms No nucleus
Prokaryotic
Eukaryotic
Basic, single-celled organisms
No nucleus
No membrane-bound organelles
Ex: bacteria
Complex, multicellular organisms
Have nucleus
Have membrane-bound organelles
Come in 2 varieties- animal & plant cells

7. 2 Types of Eukaryotic Cells
Animal
Plant

8. Differences between Animal & Plant Cells
Animal Cell
Shape= Circular
Only have Cell Membrane
Small Vacuole
Plant Cell
Shape= Rectangular
Cell Membrane AND Cell Wall
Large Vacuole
Chloroplasts

9. Cell Structure & Function
*Know all organelles!

10. Surrounding the Cell
Cell Membrane (A+P)
Cell Wall (P)

11. Cell Membrane
Function: Outer membrane of cell that controls movement in and out of the cell
Nickname: none
Location: outside covering
BOTH

12. Cell Wall Function: extra layer of support and protection
Nickname: none
Location: outside of cell membrane
PLANT ONLY

13. Inside the Cell

14. Cytoplasm Function: hold all organelles in place
Nickname: “Gel-like” substance
Location: Surrounded by cell membrane
BOTH

15. Nucleus Function: directs all cell activities
Nucleolus- dark spot in middle, helps make ribosomes
Chromatin- strands of DNA
Nickname: “control center”
Location: center of cell, separated from cytoplasm by nuclear membrane
BOTH

17. Endoplasmic Reticulum
Function: moves materials around in cell
Nickname: “delivery system” of the cell
Location: in cytoplasm, surrounds nucleus
BOTH

18. Ribosomes Function: make proteins Nickname: none
Location: in cytoplasm, either loose or attached
BOTH

19. Mitochondria
Function: produce energy through chemical reactions (breaking down fats & carbohydrates)
Nickname: “powerhouse” of the cell
Location: cytoplasm
BOTH

20. Golgi Bodies
Function: modify and package proteins so they can be transported in and out of the cell
Nickname: the “shippers”
Location: cytoplasm, near outer edge of cell
BOTH

21. Lysosome
Function: break down food for cell to use, and destroy old cell parts
Nickname: the “clean-up crew”
Location: cytoplasm (circular, but larger than ribosomes)
ANIMAL ONLY

22. Vacuole
Function: store water and items for digestion, and for waste removal
Nickname: “storage compartment”
Location: cytoplasm
BOTH
*very large in plants, helps plants maintain shape

23. Chloroplast
Function: do photosynthesis (making chemical energy from sunlight); *chlorophyll; green pigment
Nickname: none
Location: cytoplasm
PLANT ONLY!
