Document Summary
Prokaryotic: bacteria&archaea. nucleoid, not surrounded by a separate membrane with a few exceptions. Colonial: separate them, if die, not colonial but muticellular. e. g. jellyfish, coral, algae. Multi-cellular: in a single multi-cellular organism there are multiple types of cells that can be very different, which are organized into groups(tissues) that carry out different functions. Major bioelements99%dry weight: c, h, o, n, p, s. minor bioelements: zn, cu, ca, mg, fe. 4 molecules predominantly in dry cell: proteins, polysaccharides, nucleic acids(dna, rna) and lipids. Generally the volumn of eukaryotic is 1000 times than prokaryotic. Bacteria: largest degree of nutritional diversity. e. g. light. Archaea: less nutritional diverse, inhabited in extreme environments. Two cell same in size as the parental cell. Bacterial cell population growth: 1. in a fixed volume of growth media in a container(flask). a) lag phase, adapting. b) exponential phase. c) stationary phase. d) death phase 2. in nature.
