Robert Hooke

Traditional Cell Theory
- Energy flow occurs within cells
- Cells contain hereditary information (DNA) that is passed from cell to cell during cell division
- All cells are basically the same in chemical composition of similar species
Modern Cell Theory
what are the 2 main cell types?
Prokaryotic Cells and Eukaryotic Cells
what cells are bacteria, staphylococcus, e. coli, and strep throat?
prokaryotes
what cells are larger, more advanced, have a nucleus, have many internal membranes around organelles, and arose from prokaryotes about 1 billion years ago?
Eukaryotes
what cells are protists, fungi, animals, and plants?
Eukaryotes
cell membrane, cytoplasm - liquid or jelly-like substance, DNA, ribosomes, both carry out all living activities are things that what?
Things that Prokaryotes and Eukaryotes have in common?
what states that eukaryotic cells arose from living communities formed by prokaryotic organisms?
The Endosymbiotic Theory
what is the structure of a cell that acts as a specialized organ and actually means “little organ?”
Organelle
