3. The cell theory states the following:
All living things are composed of cells.
Cells are the basic units of structure and function in living things.
All cells are produced from other cells.
What are Cells?
The cell theory states the following:
All living things are composed of cells.
Cells are the basic units of structure and function in living things.
All cells are produced from other cells.

4. Two Types of Cells:
1. Prokaryotic cells lack membrane-bound internal structures. Organisms whose cells lacks a nucleus.
2. Eukaryotic cells contain membrane-bound structures. Organisms with cells that contain nuclei.

5. Eukaryotic Cell Organelles and Function
Nucleus
Nickname: “The Control Center”
Function: holds the DNA
Parts:
Chromatin: strands that contain genetic material
Nucleolus: dark spot in the middle of the nucleus that helps make ribosomes
Nuclear Membrane: Surrounds the nucleus
Plant and animal cells

7. Eukaryotic Cell Organelles and Function
Ribosomes
Function: makes proteins
Located: 2 places - Connected to the ER and all throughout the cell.

Smooth Endoplasmic Reticulum
Rough Endoplasmic Reticulum
Go to Section:

9. Eukaryotic Cell Organelles and Function
Endoplasmic Reticulum (ER)
Nickname: “Roads”
Function: The internal delivery system of the cell
Located: Close to the nucleus
2 types: 1. Rough ER – Has the ribosomes attached to it Smooth ER – does not have ribosomes attached to it.
Plant and animal cells

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

13. 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
Located: Cytoplasm

15. 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
Located: Cytoplasm
Plant and animal cells

17. Plant Cell Figure 7-5 Plant and Animal Cells Vacuole Cell Membrane

Vacuole
Cell Membrane
Go to Section:

18. Eukaryotic Cell Organelles and Function
Vacuoles
Function:
Plant Cells
Very large and only one
stores water
This is what makes lettuce crisp
When there is no water, the plant wilts
Animal Cells
Smaller and several in number
Stores/releases waste products
used in cellular digestion
Located: Cytoplasm

20. Eukaryotic Cell Organelles and Function
Chloroplasts
Function: traps energy from the sun to produce food for the plant cell
Located: Cytoplasm
Green in color because of chlorophyll, which is a green pigment
Plant cells

Go to Section:

23. Eukaryotic Cell Organelles and Function
Cell Wall
Function: provides support and protection to the cell membrane
Located: Found outside the cell membrane in plant cells
What is Cell Wall made of: Strong material called cellulos

25. Eukaryotic Cell Organelles and Function
10. Cell Membrane
Functions:
separates the inside of the cell from its environment
Controls what substances enter and leave the cell
Oxygen, carbon dioxide, wastes, food, etc…
Located:
In plant cells, it is to the inside of the cell wall
In animal cells, it is the outermost part of the cell

26. Centrioles
Function: Helps the cell divide (mitosis)
Located: Near the nucleus
Made of: Microtubules
Found in: Animal Cells only

27. Cytoplasm
Function: Gel like substance that fills the cell and holds the organelles in place.
Found In: Plant and animal cells
