Question | Answer |
Plasma membrane | Phospholipid bilayer containing cholesterol, proteins and carbohydrates |
Cytoplasm | Contains cytosol, inclusions and organelles |
Cytosol | Viscous fluid w/dissolved solutes |
Organelles | Membrane and non-membrane bound stuctures w/unique functions and actions |
Inclusions | Droplets of melanin, protein, glycogen granules, or lipid; usually non-membrane bound |
Nucleus | Surrounded by double membrane and contains nucleolus and chromatin |
Nuclear envelope | Double membrane boundary btwn cytoplasm and nuclear contents |
Nuclear pore | Openings through the nuclear envelope |
Nucleolus | Spherical, dark-staining, dense granular region in the nucleus |
Chromatin and chromosomes | Filamentous association of DNA and histone proteins |
Site of genes in the DNA | Chromatin and chromosomes |
Synthesizes rRNA and assembles ribosomes in the nucleus | Nucleolus |
Allow for passage of materials btwn nucleus and cytoplasm | Nuclear pores |
Holds the pores that regulates the exchange of materials with the cytoplasm | Nuclear envelope |
Control center; DNA and ribosome subunit assembly | Nucleus |
Carry out specific metabolic activities | Organelles |
Store materials | Inclusions |
Provides support for organelles and where diffusion occurs | Cytosol |
Site of metabolic processes of the cell and stores nutrients and dissolved solutes | Cytoplasm |
Contains receptors for communication and forms intercellular connections | Plasma membrane |
Smooth endoplasmic reticulum | Membrane bound-Interconnected network of membrane tubules and visicles;no ribosomes |
Rough endoplasmic reticulum | Membrane bound-Flattened intracellular network of membrane sacs call cisternae; ribosomes attached on cytoplasmic surface |
Golgi apparatus | Membrane bound-Stacked series of flattened, smooth membrane sacs with associated shuttle vesicles |
Lysosomes | Membrane bound-Membrane sacs with digestive enzymes |
Peroxisomes | Membrane bound-Membrane enclosed sacs; usually contain large amounts of specific enzmes to break down hamrful substances |
Mitochondria | Membrane bound-Double membrane structures w/cristae; liquid matrix contents at center |
Ribosomes | Non-membrane bound; Dense cytoplasmic granules w/2 subunits (large & small) and are free or fixed |
Cytoskeleton | Non-membrane bound; Organized network of protein filaments or hollow tubules |
Microfilaments | Non-membrane bound; Actin protein monomers formed into filaments |
Intermediate filaments | Non-membrane bound; Various protein components |
Microtubules | Non-membrane bound; Hollow cylinders of tubulin protein; able to lengthen and shorten |
Centrosome | Nonmembrane bound-Amorphous region adjacent to the nucleus; contains a pair of centrioles |
Cilia | Non-membrane bound; Short, membrane-attached projections containing microtubules. In large numbers on exposed membrane surfaces |
Flagellum | Non-membrane bound; Long, singular membrane extension containing microtubules |
Microvilli | Nonmembrane bound-Numerous thin membrane folds projecting from the free cell surface |
Synthesizes lipids, metabolizes carbs, and detoxifies drugs/alcohol | Smooth ER |
Synthesizes proteins for secretion, new proteins for the plasma membrane, lysosomal enzymes and transports/stores molecules | Rough ER |
Modifies, packages, and sorts newly synthesized proteins for secretion, inclusion in new plasma membrane, or lysosomal enzyme synthesis | Golgi apparatus |
Digest materials or microbes ingested by the cell and removes old/damaged organelles | Lysosomes |
Term that means "to self-destruct" (lysosomes do this) | Autolyze |
Convert hydrogen peroxide that is formed during metabolism to water | Peroxisomes |
Synthesize most ATP during cellular respiration. AKA-powerhouse | Mitochondria |
Synthesizes proteins | Ribosomes |
What synthesizes proteins for use within the cell? | Free ribosomes |
What synthesizes proteins for secretion, incorporation into plasma membrane, or lysosomes? | Fixed ribosomes |
