1. Cell Structure and Functions

2. Cell Theory There are three parts to the cell theory
1. all living things are made of one or
more cells
2. cells are the basic units of structure
and function in organisms.
3. All Cells arise from pre-existing cells

3. Cell Organelles What are organelles?
internal compartments that carry out specific cell functions
How are organelles beneficial to a cell?
They allow the cell to grow larger and become more specialized

6. Smooth endoplasmic reticulum
Syntheisizes steroids
Detoxifies poisons (alcohol)
Transports substances
Regulates calcium levels for muscle contraction

7. Vesicle
Membrane-sac that transports materials

8. Golgi Apparatus membrane-bound structure
organelle modifies molecules and packages them into small membrane bound sacs called vesicles

9. Mitochondria Membrane bound organelles Powerhouse of the cell
Energy production for cells
Sites of aerobic respiration
“mitochondria makes me mighty”

10. Lysosomes digests waste materials and food within the cell
breaks down molecules into their base components with strong digestive enzymes

11. Assist with cell division : helps to move chromosomes
centrioles
Assist with cell division : helps to move chromosomes

12. Plant Cell Plant cells have different structures Contains: Cell wall
Chloroplast
Vacuole (large central, takes up most part of cell)

13. Microtubules Nuclear envelope Vacuole Cytoplasm Golgi Microvilli
Microtubules
Vacuole
Golgi
Smooth E.R.
Rough E.R.
Nucleolus

Nuclear envelope
Cytoplasm
Microvilli
Ribosomes
Centrioles
Mitochondria

14. Extensions of membrane
Fluid portion
Processes/packages
Synthesizes proteins
Transportation (ribosomes attached)
Transportation (also makes lipids)
G. Transportation (move to cell membrane)
H. Internal support
I. Makes ribosomes
J. Barrier for nucleus
K. Stores food/water
L. Releases energy in food
M. Assists with cell reproduction
