ATI TEAS 6 SCIENCE ANATOMY AND PHYSIOLOGY EXAM STUDY GUIDE AND QUESTIONS AND ANSWERSScience Cell Cell: basic organizational unit of all living things. One thing in common is they all have membranes (phospholipids). Cell structure organization: All cells contain DNA, and RNA & can synthesize proteins. Consists of nucleic acids, cytoplasm, and cell membrane. oTissues: Cells that are grouped together oOrgans: Tissues that are grouped together oSystems: Organs that are grouped together oOrganism: A complete individual Nuclear parts of a cell oNucleus: contains chromosomes, & regulates DNA of the cell. Defining structure of eukaryotic cells (they all have nucleus). Passes genetic traits between generations. Contains nuclear envelop, nucleoplasm, nucleolus, nuclear pores, chromatin, & ribosomes. oChromosomes: thread like rods of DNA. Short deoxyribonucleic acid, DNA is the genetic material that stores information about the plant/animal. oChromatin: DNA & Protein makeup chromosomes oNucleolus: Proteins, small/round doesnt have membrane. Protein synthesis, synthesizes & stores RNA. oNuclear envelope: Encloses structures within nucleus. Made of lipids. oNuclear pores: Exchange materials between the nucleus * cytoplasm oNucleoplasm: Liquid like cytoplasm, within nucleus. Cell Membranes Cell Membrane (Plasma membrane): Semipermeable membrane of lipids and proteins. Made of phospholipid bilayer, hydrophilic ends of the outer layer facing the
