1. Definition of Cell
A cell is the smallest unit of life that can perform ALL the life functions.

2. Cell Theory All living things are made up of cells.
Cells are the smallest working units of all living things.
All cells come from preexisting cells through cell division.

3. Examples of Cells Amoeba Proteus Plant Stem Bacteria Red Blood Cell
Nerve Cell

4. Eukaryotic Prokaryotic
Two Types of Cells
Eukaryotic
Prokaryotic

5. Prokaryotic Cell Prokaryotes No nucleus No membrane bound organelles
Unicellular
Some have cilia (hair-like structures) and some flagella (whip-like tail) for movement.
Example:bacteria

6. Eukaryotic Cell Contain organelles surrounded by membranes
Most living organisms, (multicellular)
Plant
Animal

7. Prokaryotes vs. Eukaryotes
No nucleus
No organelles
Bacteria
Much smaller
Unicellular
Eukaryotes
Nucleus
Organelles
Unicellular (protists) and multicellular (animal and plants)
Amoeba
Plant Cell

8. Animal Cell Plant Cell

9. Cell Parts Organelles little organs inside of a cell.
They are used to:
transport of materials
capture and release energy
Building proteins
waste disposal
Send and receive information
movement
Cell membrane
Cell wall
cytoplasm
Nucleus
Chromosomes
Endoplasmic reticulum
Smooth / rough
Ribosomes
Mitochondria
Golgi bodies
Vacuoles
Lysozome
Chloroplast

10. Animal Cell Figure 7-5 Plant and Animal Cells Section 7-2
Go to Section:

11. Cytoplasm Gel-like mixture Nickname: Cell Jelly
Function: Provides the cell with structure and support

12. Eukaryotic Cell Organelles and Function
Cell membrane
Nickname: “The Gate”
Function:
Controls movement in and out of the cell

13. Eukaryotic Cell Organelles and Function
Nucleus
Nickname: “The Control Center”
Function: Directs cells activities/holds DNA

14. Chromosomes In nucleus Made of DNA
Contain instructions for traits & characteristics
Contains hereditary material

15. Do Now
Describe the differences between prokaryotic and eukaryotic cells.

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

17. Endoplasmic Reticulum
2 Types:
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

18. Eukaryotic Cell Organelles and Function
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. Eukaryotic Cell Organelles and Function
Golgi Bodies
Nickname: The Post office
Function: packages, modifies, and transports materials to different locations inside/outside of the cell.
Appearance: stack of pancakes

20. Eukaryotic Cell Organelles and Function
Ribosomes
Nickname: “Construction Workers”
Function: makes proteins
Found in all cells, prokaryotic and eukaryotic

21. Eukaryotic Cell Organelles and Function
Lysosomes: circular, but bigger than ribosomes)
Nickname: “Cellular Stomach”
Function: digests food into small particles the rest of the cell can use and to destroy old cells.

22. Plant Cell Now let’s talk about structures only found in PLANT Cells!!

Now let’s talk about structures only found in PLANT Cells!!

23. Eukaryotic Cell Organelles and Function
Vacuoles
Nickname: Water Tower
Function: stores water
This is what makes lettuce crisp
When there is no water, the plant wilts
Found in animal cells too, but much smaller.

24. Eukaryotic Cell Organelles and Function
Cell Wall
Nickname: The Protector
Function: provides support and protection to the cell membrane
Found outside the cell membrane in plant cells

25. Eukaryotic Cell Organelles and Function
Chloroplasts
Nickname: Solar Panels
Function: traps energy from the sun to produce food for the plant cell
Green in color because of chlorophyll, which is a green pigment

26. Plant vs. Animal Cells Plants Animals Cell wall Cell membrane
Chloroplasts
Large vacuole
Animals
Cell membrane
No Chloroplasts
Smaller vacuoles
