Document Summary
Ebio exam 2 topics: cell diversity, the human microbiome: Archaea, bacteria, eukarya (plantae, fungi, animalia, protists) a) prokaryote = no nucleus = no membrane around the dna b) eukaryote = nucleus = membrane around dna. Eukaryotes vs. prokaryotes a) similarities: (1) all living cells share these key components: Nucleic acids (dna) to store genetic information for protein synthesis. Proteins to perform diverse tasks (and ribosomes to make proteins) Outer cell membrane to maintain a suitable internal environment. Ability to acquire energy from environment for atp formation & the. 3 types of cellular work b) differences (1) prokaryotes: smaller, simpler structure, dna concentrated in nucleoid region, which is not enclosed by a membrane (2) eukaryotes: larger, more complex structure, nucleus enclosed by membrane, contains many types of organelles. D. endosymbiont theory: engulfed non-photosynthetic prokaryotes become mitochondria (slide 11, ppt 9 cell diversity) E. chloroplasts, cell wall, and central vacuole are all unique features of plant cells.
