1. active transport: most larger water-soluble or charged molecules are transported by a pump or a carrier and involve the integral proteins 2. aging: may involve cell damage due to free radicals as a result of normal cell metabolism or cell injury due to radiation and chemical pollutants 3. anaphase: the V-shaped chromatids are pulled apart 4. aneuploidy: abnormal number of chromosomes, can be trisomy and monosomy 5. Apoptosis: programed cell death 6. Benign neoplasm: tumor; local mass, remains compacted, often encapsulated, grows slowly and seldom kills the host 7. bulk transport: exocytosis and endocytosis 8. cancer: A cell mass which divides and multiplies abnormally; neoplasm 9. cardiac muscle: involuntary muscle"; specialized kind of muscle found only within the heart 10. catalase: break down poisons like alcohol, phenol and formaldehydes that have entered the body 11. cell division: mitosis 12. Cell life cycle: Interphase, Cell Division 13. cell muscle contractions: Actin interacts with another protein called myosin 14. cell: plasma membrane, cytoplasm, nucleus 15. centrioles: paired cylindrical bodies perpendicular to one another and each composed of nine triplets of microtubule; organize a microtubule network during mitosis to form the spindle and asters; form the bases of cilia and flagella 16. Centrosome: spherical structure in the cytoplasm near the nucleus; contains matrix and centrioles 17. Chromatin: granular thread-like material in the nucleus composed of DNA 18. chromosomes: contains a single, very long molecule of DNA. There are 46 in a typical human cell 19. classification of epithelial cells: squamous, cuboidal, columnar 20. Clathrin protein: found on the cytoplasmic side of the infolding is responsible for deforming the membrane

21. Cytokinesis: For a short period, the cell has 2 nuclei until it is completely separated by the process of 22. cytoplasm: cellular region between the nucleus and plasma membrane 23. Cytoplasmic inclusions: Impermanent structures in the cytoplasm such as lipid droplets and glycogen containing glycosomes 24. cytoskeleton: Is a network of rods running throughout the cytosol to support the cellular structure and generates movements of the cell 25. cytosol: viscous fluid containing water, ions and enzymes, inclusions containing stored nutrients and pigments and organelles 26. diffusion: movement of small uncharged particles 27. DNA: double helix chains of nucleotide molecules 28. endocytosis: Brings large molecules into the cell, through an initial infolding part of the plasma membrane that encloses them to form
