1. Cell Structure & Function

2. Quick: Discuss with your table partner what you think a cell is
Quick: Discuss with your table partner what you think a cell is. What do you think a Cell does?

3. Scientific Discoveries about the Cell
Robert Hooke-first person to see cells and use the term “cell”. Thought it looked like many boxes under the microscope.
Anton van Leeuwenhoek- saw first living single celled organism under a microscope.
Schwann, Shleiden & Virchow- Cell Theory

4. All Cells have 3 basic features
1) Cell membrane- thin, semi-permeable barrier that surrounds and encloses the contents of a cell. It supports and helps maintain a cell's shape.

5. 2) Genetic Material-DNA
3)Cytoplasm-is a thick solution that fills each cell and is enclosed by the cell membrane.

6. 2 Types of Cells-Prokaryote & Eukaryote
1)no membrane bound nucleus
2)Chromosomes grouped together in an area called the “nucleoid”
3)No membrane bound organelles
4)smaller than the eukaryote cells

7. Eukaryote
Organelles-membrane-bound structures in a cell that performs a special function.
Nucleus
Golgi apparatus
Lysosome
Mitochondrion
Endoplasmic reticulum
ribosome
Has a membrane bound nucleus and organelles
Plants, animals, fungi and protista cells

8. Organelle functions Nucleus-control center for the cell
Golgi apparatus-gathers simple molecules and combines them to make molecules that are more complex
Lysosome-hold enzymes that were created by the cell. The purpose of the lysosome is to digest things
Mitochondria- act like a digestive system  which takes in nutrients, breaks them down, and creates energy rich molecules for the cell. 
Endoplasmic Reticulum-functions as a manufacturing and packaging system
Ribosome-are the protein builders or the protein synthesizers of the cell
