1
Cell Theory There are three main parts of the cell theory – the theory states: All living things are made of cells Cells are the basic unit of structure and function in living things All cells are produced from existing cells
2
Cells A couple more things…
Living things can be made of only one cell or many cells Cells are about 70% water Cells are made up of organelles?
3
Plant vs. Animal PLANT -square shape -cell wall -central vacuole -chloroplast -photosynthesis ANIMAL -Rounder shape -centrioles -must eat, can’t make energy from light
4
Cell Wall (only in plants)
Function: supports and protects the cell Also involved in cell communication
5
Central Vacuole (only in plants)
Function: Stores water and minerals and other nutrients
6
Chloroplast (only in plants)
Function: Photosynthesis Makes sugar and oxygen from sunlight, water, and carbon dioxide
7
Cell Membrane Function: To control what enters and leaves the cell.
Aids in protection against pathogens
8
Cytoplasm Function: Gel substance that supports the contents of the cell Chemical reactions take place here
9
“Mighty” Mitochondria
Function: Cellular Respiration The power house of the cell that converts sugar from plants into ATP. ATP is the fuel for your cells and gives you ENERGY!!!
10
Nucleus Function: Stores hereditary information (DNA) and controls the cell by protein synthesis
11
Chromatin Function: Controls the cell and contains instructions for making proteins ALSO KNOW AS D.N.A.
12
Lysosome Function: Breaks down food, materials, waste, old cell parts, and toxins in the cell. It is filled with enzymes (enzymes speed up reactions) CLEAN UP CREW!
13
Nucleolus Function: Makes Ribosomes
14
Ribosomes Function: Makes proteins
15
Rough Endoplasmic Reticulum (ER)
Function: Makes proteins and transports substances through the cell
16
Smooth Endoplasmic Reticulum
Function: Manufactures hormones Transports materials Detoxifies the liver of organic compounds Adds calcium when needed
17
Vesicle Function: Stores materials in the cell
19
Part Four
20
Golgi Complex Function: Packaging and distribution center of the cell
21
Peroxisomes Function: Breaks down hydrogen peroxide into water and oxygen This detoxifies the cell
22
Centrioles (only in animals)
Function: Aids in cell division
23
Microfilaments Function: Protein fiber that help the cell contract and move
24
Microtubules Function: Make up the cytoskeleton of the cell.
Support the cell under the membrane and keeps the organelles in place.
25
Flagella Function: Long whip like tail that is used for movement
26
Cilia Function: Short hair like organelle that allows some cells to move
