Eukaryotes: model organisms of each group 5. Eukaryotic diversity protists, fungi, plants and animals [scan ch. 22-26; see in particular the (cid:862)(cid:272)hara(cid:272)teristi(cid:272)s(cid:863) summaries in the review sections, i. e. 22. 2, 23. 1, 24. 1, 25. 1] Basic cell structures cell wall, plasma membrane, non-membrane bound organelles (e. g. cytoskeleton, ribosomes), membrane-bound organelles (e. g. nucleus, endoplasmic reticulum, golgi complex, lysosomes, peroxisomes, vacuole, vesicles, mitochondria, chloroplasts) [ch. 2. 2-2. 4] see also (cid:271)elo(cid:449) (cid:862)the origi(cid:374) a(cid:374)d e(cid:448)olutio(cid:374) of cells(cid:863) se(cid:272)tio(cid:374) titled (cid:862)eukaryoti(cid:272) cells(cid:863) Sections: full article (cid:862)the universal features of cells on earth(cid:863) (cid:862)the origin and evolution of cells(cid:863) The fundamental unit of life, and every organism consists of cells or is itself a single cell. Self-regulating: membrane composed of proteins and lipid, organelles structured onto cytoskeleton floating in cytoplasm, genetic information, metabolic processes, adaptable, reproduces by mitosis or meiosis (in gametes) All these ideas were formalized in the (cid:1005)8(cid:1004)(cid:1004)(cid:859)s as the cell theory: All organisms consist of one or more cells.
