1. The CELL
-Just like our bodies, cells must have different structures which help them live.
-They need their own version of skin, a stomach, blood and a brain to survive.

2. Leuwhenhoek invented What?
Hooke named the cell

3. Technology advanced Electron Microscope
What did it allow us to C ?

4. Organelles EUKARYOTES have ORGANELLES Organelles
PROKARYOTES NO MEMBRANE BOUND ORGANELLES
EUKARYOTES have ORGANELLES
Organelles
are small structures found inside the cell which have special jobs to help the cell survive.

5. Cell Membrane
1. The plasma membrane is the boundary between the inside of the cell and the outside of the cell.

6. Cell Membrane Selectively permeable Also called the Plasma Membrane
Selectively permeable, which means it only lets certain things into and out of the cell.
Selective Permeability

7. Homeostasis Cell Membrane helps maintain homeostasis inside the cell.
Homeostasis relative constant internal physical and chemical conditions an organism wants to maintain.
Example your temperature blood sugar

8. Cell membrane
-The plasma membrane is a phospholipid bilayer which means that it is made up of two stacks of lipids attached to phosphates with proteins in between them.

9. Cell Membrane
Scientists describe the plasma membrane using the fluid mosaic model; this means that the lipids move around a lot which makes the plasma membrane very flexible.

10. NUCLEUS THE BRAIN
The nucleus is called the control center of the cell because it stores DNA which contain directions for making proteins.
The nucleolus is found inside the nucleus and is where ribosomes are made.
Nucleolus contains ribosomes
Nucleus contains DNA

11. RIBOSOMES
Ribosomes are made inside the nucleolus and then leave the nucleus by the nuclear pores and attach to the endoplasmic reticulum where they make proteins or float in the cytoplasm.
Ribosomes

12. Endoplasmic Reticulum
The Endoplasmic Reticulum or E.R. is a highly-folded organelle where proteins and lipids (fats) are synthesized. Synthesis means to make something.

13. Golgi Apparatus FED EX UPS
The Golgi Apparatus sorts and packages the proteins and lipids made in the E.R. and sends them around the cell. The Golgi Apparatus is like the post office of the cell!

14. Cellular Respiration C6H12O6 + 6O2 6CO2 +6H2O +energy (36atp)
The Mitochondria is called the powerhouse of the cell because it breaks down sugar into energy in the form of ATP.

15. Lysosome Garbage Man
The lysosomes contain digestive enzymes which break down waste. The lysosomes help digest things we no longer need in our cells so that the cell can get rid of these waste products.

16. CYTOSKELETON
The cytoskeleton provides support in our cells.

17. CYTOPLASM
The cytoplasm is the gel-like liquid inside the cell. The cytoplasm moves around to provide nutrients to the different organelles inside the cell. In this way, the cytoplasm helps circulate materials inside the cell.
