Document Summary

Biology: the science of how life works: molecular mechanisms with the cell, integrated actions of many cells. Characteristics of life: contain one or more cells, reproduce (genetic material = information, sustain/produce energy, growth (and development, regulation (homeostasis, response (to environment, adapt. Biological community: are (cid:448)iruse"s ali(cid:448)e, they do(cid:374)"t fit all the characteristics of life, it"s protei(cid:374) (cid:449)ith ge(cid:374)etic (cid:373)aterial. Prokaryotic and eukaryotic cells: karyo always refers to genetic material, eukaryotic has nucleus and compartments, prokaryotic happens in cytoplasm, single cell, both have plasma membrane, endoplasmic reticulum photosynthesis & detoxification. Features of cell: store & transmit information, has plasma membrane, can harness energy from environment. Harnessing energy: two sources, sun, chemical compounds (atp!!!!, metabolism life sustaining chemical reactions that occur with the cells of a living organism, catabolic, anabolic. Cell theory: all organisms are made up of cells. Ix: cell is the fundamental unit of life, cells come from preexisting cells.
