1. Cell Structure & Function

2. Cells All living things are made up of cells.
Cells are the smallest working units of all living things.

3. Definition of Cell
A cell is the smallest unit that is capable of performing life functions.

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

5. “Typical” Animal Cell Cell membrane Cytoplasm Nucleus Mitochondrion
Vacuole

6. “Typical” Plant Cell Cell wall Cell membrane Chloroplasts Nucleus
Vacuole
Cytoplasm

7. Cell Parts
Organelles

8. Surrounding: Cell Membrane (plant & animal)
Outer membrane of cell that controls movement in and out of the cell
Double layer

9. Inside the cell: Nucleus (plants & animals)
Directs cell activities
Separated from cytoplasm by nuclear membrane
Contains genetic material - DNA

10. Vacuoles (plant & animal)
Membrane-bound sacs for storage, digestion, and waste removal
Contains water solution
Help plants maintain shape

11. Cytoplasm (plant & animal)
Jelly-like mixture
Surrounded by cell membrane
Contains hereditary material
Helps the cell stay healthy

12. Surrounding: Cell Wall (plant)
Most commonly found in plant cells & bacteria
Supports & protects cells

13. Chloroplast (plant) Contains green chlorophyll “makes plants green”
Makes food for plant cells

14. Inside the cell: Mitochondria (plant & animal)
Produces/Releases energy through chemical reactions – breaking down fats & carbohydrates
Controls level of water and other materials in cell
Recycles and decomposes proteins, fats, and carbohydrates

15. Review

16. No Cell wall
Flexible cell membrane
no chloroplast
Smaller vacuoles
cell membranes nuclei cytoplasm mitochondria lysosomes
Cell wall
Rigid cell membrane
Have chloroplast
Large vacuoles
Make their own food

17. Lysosomes (plant &animal)
“Digestion” system of cells. One of its functions is the digestion of lipids, carbohydrates, and proteins into small molecules that can be used by the rest of the cell. Lysosomes are also involved in the breakdown of organelles that have outlived their usefulness.

18. Organelle Simile Book
Write similes for the following organelles: nucleus, chromosomes, cell membrane, cell wall, cytoplasm, vacuole, vesicle, and mitochondrion. 1 PAGE PER ORGANELLE
EXAMPLES:
A cell membrane is like a guard at the door, it decides what comes in the cell and what goes out of the cell.
The nucleolus is like a boss, it gives directs the cell’s activities
