1. Plant & Animal Cells

2. The Discovery of Cells
Robert Hooke in 1663 looked at plant cells under a microscope and thought they looked like the cells monks lived in within their monasteries.
As our microscopes became more powerful over the years, we have learned a great deal more about the inner workings of the cell.

3. Cell Theory
The cell theory outlines the importance of cell to living things.
Cells are the basic structures that make up living things.
Cells dictate the function of living things.
All cells come from preexisting cells.
The average human body contains between trillion cells.
100,000,000,000,000 cells!!!

4. Cell Organelles
A cell is like our body in that it has a number of parts that must all work together in order for the cell to function properly.
These little parts within the cell are called organelles (little organs).
Organelles look after a number of jobs within the cell such as…
Intake of nutrients
Movement
Growth
Responsiveness
Gas exchange
Waste excretion
Reproduction

5. Cell Membrane
The cell membrane is a protective barrier around the cell.
It controls what goes into or out of the cell.
Security!!!

6. Cytoplasm
The cytoplasm is a jelly-like substance that fills the cell and surrounds the organelles.
It contains the nutrients that the cell needs to survive.
The Work Place!!!

7. Nucleus
The nucleus is the control centre of the cell. It controls all cell actvities.
The nucleus is where you will find the DNA for the cell.
Nucleolus inside.
The Boss!!!

8. Mitochondria The mitochondria produce energy for the cell.
Cellular Respiration
Sugar  ATP!!!
Powerhouses!!!

9. Ribosomes Ribosomes are the tiny protein builders within the cell.
Proteins are the “working molecules” of the body.
Workers!!!

10. Golgi Apparatus
The Golgi apparatus modifies, sorts and packages proteins for delivery within or out of the cell.
The Golgi makes vesicles for transport.
Shipping & Receiving!!!

11. Endoplasmic Reticulum
The ER is a series of tubes made of the same stuff as the cell membrane.
Rough ER helps make proteins with the ribosomes.
Smooth ER makes fats and oils.

12. Vacuoles & Vesicles
Vacuoles and vesicles store nutrients, waste and other substances.
Vesicles can also be used for transporting substances in the cell.
Storage rooms & Boxes!!!

13. Lysosomes Lysosomes digest materials in the cell using enzymes.
The breakdown invaders and old parts of the cell.
Bouncers & Recyclers!!!

14. Cytoskeleton
The cytoskeleton is made of protein filaments and helps the cell maintain its shape.
Structure equals Function!!!
Iron Girders!!!

15. Cell Wall
The cell wall is only in plant cells and it is a rigid frame that provides strength, protection and support.
The Great Wall!!!

16. Chloroplasts
The chloroplast is only in plants and it carries out the process of photosynthesis.
They make glucose…sugar!!!
Solar Panels!!!
