1. CELL STRUCTURE and FUNCTION

2. Cell Organelles Little organs Parts that make up the cell
Analogy– Like the organs that make up the human body – (heart, lungs, kidneys, blood vessels, blood, etc)

4. Eukaryotic Cell Organelles and Function
Nucleus
Nickname: “The Control Center”
Function: holds the DNA
2. Nucleolus: dark spot in the middle of the nucleus
Function: Makes ribosomes

Ribosomes
Function: makes proteins
Found in all cells, prokaryotic and eukaryotic

7. Eukaryotic Cell Organelles and Function
Endoplasmic Reticulum (ER)
Nickname: “Roads”
Function: The internal delivery system of the cell

9. 2 Types Of ER Rough ER: Rough appearance because it has ribosomes
Function: helps make proteins, that’s why it has ribosomes
Smooth ER:
NO ribosomes
Function: makes fats or lipids

5. Golgi Complex
Nickname: The shippers
Function: packages, modifies, and transports materials to different location inside/outside of the cell
Appearance: stack of pancakes

14. Eukaryotic Cell Organelles and Function
Lysosomes: circular, but bigger than (ribosomes)
Nickname: “Clean-up Crews”
Function: to break down food into particles the rest of the cell can use and to destroy old cells

Mitochondria
Nickname: “The Powerhouse”
Function: Energy formation
Breaks down food to make ATP
ATP: is the major fuel for all cell activities that require energy

19. 8. Cell membrane Function- Regulates what enters and leaves the cell
- also provides support and
protection
Location- outside covering of the cell
“semi permeable”- only certain things can move in or out of the membrane

20. 9. Cytoskeleton Function- acts as the muscles and bones of the cells
- support and shape
2 types
1. microfilaments – aid in movement
2. microtubules- aid in structure

21. 10. Centrioles Only found in animal cells
Function- pulls chromosomes apart during cell division—mitosis
Location- near nucleus (2 of them)

22. mitosis

23. Eukaryotic Cell Organelles and Function
11. Vacuoles
Function: stores water and nutrients for cells
Plants have larger vacuoles

24. Now let’s talk about structures only found in PLANT CELLS!!

25. Organelles found only in plants
12. Chloroplasts
Function: traps energy from the sun to produce food for the plant cell
Photosynthesis take place here
Green in color because of chlorophyll

26. Eukaryotic Cell Organelles and Function
13 Cell Wall
Function: provides support and protection to the cell membrane
Found outside the cell membrane in plant cells
