Interphase - cell grows, performs its normal functions, and prepares for division; consists of G1, S, and G2 phases G1 phase - the cell grows in size and organelles double in size S phase - DNA replication ("S"= synthesize) G2 phase - cell growth, production of enzymes and other proteins two categories of mitosis - 1. karyokinesis (division of cell nucleus) 2. cytokinesis (division of cytoplasm) prophase - 1. chromatin condenses to form chromosomes; nuclear membrane and nucleoli disapp...

USABO Latest Update with Verified Solutions Eukaryote An organism whose cells contain complex structures enclosed within membranes. The defining membrane bound structure thats sets them apart from prokaryotic cells is the nucleas or nuclear envelope within which the genetic material is carried. All species of large complex species are eukaryotes, including animals, plants and funghi. Euchromatin This shows as pale areas in the nucleas under electro magnification. It is a less densly...
