ATI TEAS 6 EXAM STUDY GUIDE Science 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. o Tissues: Cells that are grouped together o Organs: Tissues that are grouped together o Systems: Organs that are grouped together o Organism: A complete individual  Nuclear parts of a cell o 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. o Chromosomes: thread like rods of DNA. Short deoxyribonucleic acid, DNA is the genetic material that stores information about the plant/animal.o Chromatin: DNA & Protein makeup chromosomes o Nucleolus: Proteins, small/round doesn’t have membrane. Protein synthesis, synthesizes & stores RNA. o Nuclear envelope: Encloses structures within nucleus. Made of lipids. o Nuclear pores: Exchange materials between the nucleus * cytoplasm o Nucleoplasm: 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 external environment, the inner layer facing inside the cell, hydrophobic ends facing each other. o Hydrophilic: Water loving, can dissolve water o Hydrophobic: Hates water, can’t dissolve water  Selective Permeability o Selective Permeability with regards to size, charge, and solubility.  Cell structure o Ribosomes: synthesize proteins from amino acids. o Golgi apparatus: synthesize materials like proteins that are transported out of the cell. Near nucleus & consists of layers of membranes.o Vacuoles: Sacs used for storage, digestion, and waste removal. One large in plant cells/ Animal cells are small or have numerous. o Vesicle: Has membrane, & can move materials within the cell. o Cytoskeleton: Microtubules that shape and support the cell. o Microtubules: Part of cytoskeleton & help support cell. Made of protein. o Cytosol: Liquid material within the cell. Mostly water & had floating materials. o Cytoplasm: Cytosol & organelles found within the plasma membrane, not within nucleus! o Cell membrane: Barrier that keeps materials out of cell. Determines what’s allowed in and out. o Rough Endoplasmic reticulum: Ribosomes on the surface, produce & store proteins o Smooth Endoplasmic reticulum: Helps store lipids & proteins. o Mitochondrion: Generate ATP, involved in cell growth & death. Contain their own DNA aside from the one within the nucleus.  Functions: Produce energy, cell signaling, cellular differentiation, cell cycle & growth regulation. Can also have aerobic respiration.  Animal Cell Structureo Centrosome: Mitosis & the cell cycle occur here o Centriole: Cellular division o Lysosome: Digests proteins, lipids, and carbohydrates. Help remove undigested substances. o Cilia: Appendages that cause a cell to move & can move fluid o Flagella: Tail like structures that help the cell move. A cell usually only has one or a few flagella. Longer than cilia.  Cell Cycle: Cell reproduces, growth cell, duplication of genetic material, and cell division.  Cell Differentiation: Helps determine the cell type for each cell, process is controlled by genes of each cell (zygote). Following the directions of the genes, a cell builds certain proteins and other substances to set it apart as a specific type of cell. [Show More]
