Unit 1 - The Cell
Cell Theory: Cell theory: refers to the idea that cells are the basic unit of structure in every living thing. It states that: ● New cells are formed from other existing cells, ● the cell is a fundamental unit of structure, ● function and organization in all living organisms.
Eukaryotic and Prokaryotic Cells
1
Prokaryotic ● ● ● ● ● ● Have pili No nucleus DNA in cytplasm Reproduce using binary fission No formal Organelles 70S Ribosomes
Eukaryotic ● ● ● ● ● ● No Pili Have Nucleus DNA in nucleus and code for proteins Divide using mitosis/meiosis Membrane bound organelles 80S Ribosomes
70S and 80S : A svedberg unit (symbol S, sometimes Sv) is a non-SI unit for sedimentation rate. The sedimentation rate is the rate at which particles of a given size and shape travel to the bottom of the tube under centrifugal force.
Binary fission in a prokaryote. 1: The bacterium before binary fission is when the DNA tightly coiled. 2: The DNA of the bacterium has replicated. 3: The DNA is pulled to the separate poles of the bacterium as it increases size to prepare for splitting. 4: The growth of a new cell wall begins to separate the bacterium. 5: The new cell wall fully develops, resulting in the complete split of the bacterium. 6: The new daughter cells have tightly coiled DNA, ribosomes, and plasmids.

Plant Cells ● ● ● ● ● Cell Wall Chloroplasts No flagellum (except algae) Have a large central vacuole No centrioles
Animal Cells ● ● ● ● ● No Cell Wall No Chloroplasts Can have flagellum Smaller Vacuole Have Centrioles
