BIOL 1001 Chapter : Cell Theory Notes
Document Summary
What is the cell theory: all cells come from preexisting cells, all organisms are made up of cells, cells are the basic unit of life, diffusion, easy flow of a substance in and out of a cell. Flagella: tail like structure, attached to the organism, provides quick motion, cilia, hair like structure, not exactly attached to organism. Sweeping motion: eukaryotic, animal cell, know all the components, nucleus region, houses the dna, endoplasmic reticulum (er, dna is transcribed to here, rough and smooth, rough, ribosomes- contribute to rna making proteins. Functions in detoxification: ups of the cell, packages the proteins, labels them, and sends them on their way, vesicle, vehicle for the proteins. Lysosomes: contain digestive enzymes, mitochondria, power house of the cell. Lots of energy: cytoskeleton, gives support and shape. Intermediate filaments: plant cell, cell wall (not in animal cells, extracellular matrix, water vesicle.
