Two basic types of cells
________________ Almost always single-celled (except for prokaryote colonies).
Reproduce by binary fission (another copy by dividing).
No cell nucleus or any other membrane-bound organelles. DNA travels openly around the cell.
All bacteria are prokaryotes.
________________
Most organisms that we can see, such as trees, grass, worms, flies, mice, humans, mushrooms and yeast are eukaryotes.
Can either be single-celled or multi-celled.
Can reproduce in one of several ways (Ex. meiosis, mitosis).
Have cell nucleus within containing its DNA.
Nucleus most evident distinction between these cell types.
