This is they Hyatt tv tv highly gotcha 1.Centrosome- an organelle near the nucleus of a cell that contains the centrioles (in animal cells) and from which the spindle fibers develop in cell division. 2. Cytoplasm-the material or protoplasm within a living cell, excluding the nucleus. 3. Endoplasmic reticulum-a network of membranous tubules within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane. It usually has ribosomes attached and is involved in protein and lipid synthesis. 4. Golgi Apparatus-a complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport. 5. Lysosome- an organelle in the cytoplasm of eukaryotic cells containing degradative enzymes enclosed in a membrane. 6. Mitochondria- an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner layer being folded inward to form layers (cristae). 7. Nucleus- the central part of most cells that contains genetic material and is enclosed in a membrane 8. Plasma membrane- a semipermeable limiting layer of cell protoplasm —called also cell membrane 9. Ribosome- any of the RNA-rich cytoplasmic granules that are sites of protein synthesis 10. 10.Active transport- the movement of a chemical substance by the expenditure of energy against a gradient in concentration or in electrical potential across a plasma membrane 11. Concentration gradient- measurement of how the concentration of something changes from one place to another. 12. Diffusion- the process whereby particles of liquids, gases, or solids intermingle as the result of their spontaneous movement caused by thermal agitation and in dissolved substances move from a region of higher to one of lower concentration 13. Endocytosis-incorporation of substances into a cell by phagocytosis or pinocytosis 14. Enzyme-a...
