1. The Cell Theory All living things are made up of cells
Cells only arise from pre-existing cells.
The cell is the basic unit of life.

2. Matthias Schleiden, Theodor Schwann and Rudolph Virchow
All three scientists contributed to Cell Theory

3. Robert Hooke English Naturalist Was the first to use the term cell.
Looked at cork cells under the compound microscope.

4. Anton van Leeuwenhoek
Anton was a Dutch scientist who is considered “the Father of microbiology.”
The first scientist to see animalcules, or tiny living things

5. Cells

6. The Cell Membrane Controls movements into and out of the cell
Is semi-permeable, or selectively permeable.
Helps maintain the shape of the cell.

7. Cytoplasm
gel-like material which contains materials involved in cell metabolism.
Holds everything in place

8. Chromosomes/DNA Contains code that guides all cell activities
They are found in the nucleus.
Chromosomes contain the genes that determine an organisms characteristics.

9. The Nucleus and The Nucleolus
THE BRAIN!
Serves as the control center of the cell and contains Deoxyribonucleic Acid (DNA)
Nucleolus- Contains RNA
Nuclear membrane – Control what goes in or out of the Nucleus.
Animal, Plant and Eukaryotes have these three organelles
Prokaryotes do not have these…

10. Mitochondria Power House of The Cell. Makes ATP/ Energy
These organelles are more plentiful in active cells

11. Endoplasmic Reticulum
Transports materials throughout the cell.
Makes lipids, breaks down materials
Rough ER contains Ribosome's.
Smooth ER has no Ribosome's
Transports materials throughout the cell.

12. Golgi Bodies
Packages and secretes the proteins made by the Ribosome's.
Look like stacks of pancakes.

13. Lysosomes
Powerful chemicals that break things down.

14. Vacuoles Plays a role in intercellular digestion Store water.
Are much larger in plant cells.

15. Prokaryote Have no formed nucleus Are unicellular
Are very disorganized.
Have a cell wall, cytoplasm, ribosomes, bacteria have cell membrane
Bacteria are prokaryotes

16. Eukaryote Have a Nucleus Have cell membrane bound organelles
Are very organized.
Can be unicellular or multi-cellular.
Have these other organelles; nuclei, mitochondrion, lysosome, golgi apparatus, ribosomes
PLANT AND ANIMAL CELLS!!!

17. Plant Cells Have two main differences from animal cells
1. Cell wall = a tough, usually flexible but sometimes fairly rigid layer that surrounds a cell
2. Chloroplasts = organelles found in plant and other eukaryotic organisms that conduct photosynthesis
