1. Cellular Communication: Answer (cellular crosstalk) how messages originate and aretransmitted, received, interpreted, and used by the cell. 2. Intercellularsignals: Answer streamlined conversation between, among, and within cellsmaintains cellular function and specialization. Allows each cell to determin its position and specialized role. 3. Chemical fondness: Answer cells must demonstrate a chemical fondness for other cellsand their surrounding environment to maintain the integrity of the entire organism. When they no longer tolerate thisfondness, the conversation breaks down and cellseither adapt (sometimes altering function) or become vulnerable to isolation, injuryor disease 4. Eukaryotes: Answer (eu = good; Karyon = nucleus) are larger and have more extensive intracellular anatomy and organization than to procaryotes. Eukarytoic cellshave a characteristic set of membrane-bound intracellular compartments, calledorganelles, that includes a welldefined nucleus. 5. Prokaryotes: Answer contain no organelles, and their nuclear material is not encasedby a nuclear membrane. Prokaryotic cells are characterized by lack of a distinct nucleus. 6. Differentation: Answer The process through which cells become specialized. Also referred to as maturation.This process results in cells performing a specific function.
