S c i e n c e • Cell: basic organizational unit of all living things. One thing incommon is they all have membranes (phospholipids). • Cell structure organization: All cells contain DNA, and RNA & cansynthesize proteins. Consists of nucleic acids, cytoplasm, and cell membrane. • Tissues: Cells that are grouped together • Organs: Tissues that are grouped together • Systems: Organs that are grouped together • Organism: A complete individual • Nuclear parts of a cell • Nucleus: 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. • Chromosomes: thread like rods of DNA. Short deoxyribonucleic acid, DNA is the genetic material that storesinformation about the plant/animal. • Chromatin: DNA & Protein makeup chromosomes • Nucleolus: Proteins, small/round doesn’t have membrane.Protein synthesis, synthesizes & stores RNA. • Nuclear envelope: Encloses structures within nucleus. Made oflipids. • Nuclear pores: Exchange materials between the nucleus *cytoplasm • Nucleoplasm: Liquid like cytoplasm, within nucleus. Cell Membranes • Cell Membrane (Plasma membrane): Semipermeable membrane of lipids and proteins. Made of phospholipid bilayer, hydrophilic ends ofthe outer layer facing the external environment, the inner layer facing
