1. Cells Structures and Their Functions

2. Cells
Are the smallest unit of life that carries out all life functions
Contain major structures inside that perform these life functions
Vary in size, but contain many of the same structures

3. Organelles (Structures) of the cell
Cell Membrane
outside covering of the a cell that controls what comes in and out of the cell
Analogy -

4. Nucleus contains Genetic Material (DNA)
is the control center of the cell
Analogy -

5. Cytoplasm gel-like fluid inside a cell
the other organelles are embedded in the cytoplasm
Analogy -

6. 1.1 Animal cell structure
All cells have three basic structures in common.
cytoplasm
nucleus
cell membrane
cytoplasm

x400
cell membrane

7. Mitochondria uses oxygen to release energy from food
sometimes called the powerhouse of the cell
Analogy -

8. Vacuoles Cell wall act as storage centers
Provides extra support and shape for plant cells, it is made mostly of cellulose
Analogy -

9. Chloroplast
food-making structures of a plant cell

10. Comparing plant and animal cell structure

11. Comparing plant and animal cell structure

12. Comparing plant and animal cell structure
Which structures both plant and animal cells have in common?
x100
x400

13. Comparing Plant and Animal Cells
Plant cells have a cell wall (to give extra support and shape), but animal cells do not.
Plant cells have chloroplasts (that enable plants make their own food), but animal cells do not.

14. Comparing Plant and Animal Cells
Plant cells usually have one or more large vacuole(s) (help provide shape and allow the plant to store water and food for future use), while animal cells have smaller vacuoles,if any are present.

15. 1.3 Cell Variety Bacteria Yeast Paramecium
Microbes are microscopic unicellular organisms. Below are some examples of different types of microbial cells.
Paramecium
Yeast
Bacteria
Osmosis animation

16. Bacteria Does not have a nucleus
Genetic material is found spread throughout the cell
