Cells the Living Units Q.1) Each daughter cell resulting from mitotic cell division has exactly as many chromosomes as the  parent cell.  A. True B. False Q.2) Apoptosis is programmed cell suicide, but cancer cells fail to undergo apoptosis.  A. True B. False Q.3) The spindle is formed by the migration of the chromatin.  A. True B. False Q.4) Final preparation for cell division is made during the cell life cycle subphase called G2.  A. True B. False Q.5) Chromatin consists of DNA and RNA.  A. True B. False Q.6) In osmosis, movement of water occurs toward the solution with the lower solute concentration.  A. True B. False Q.7) The genetic information is coded in DNA by the regular alternation of sugar and phosphate  molecules.  A. True B. False Q.8) A process by which large particles may be taken into the cell for food, protection of the body, or for  disposing of old or dead cells is called phagocytosis.

A. True B. False Q.9) The orderly sequence of the phases of mitosis is prophase, metaphase, anaphase, and telophase.  A. True B. False Q.10) Diffusion is always from areas of greater to areas of lesser concentration.  A. True B. False Q.11) Facilitated diffusion always requires a carrier protein.  A. True B. False Q.12) Pressure caused by gravity is necessary for any filtration pressure to occur in the body.  A. True B. False Q.13) DNA transcription is another word for DNA replication.  A. True B. False Q.14) The glycocalyx is often referred to as the "cell coat," which is somewhat fuzzy and sticky with  numerous cholesterol chains sticking out from the surface of the cell membrane.  A. True B. False Q.15) In their resting state, all body cells exhibit a resting membrane potential ranging from  - 50 to about  + 50 millivolts.  A. True B. False Q.16) Microfilaments are thin strands of the contractile protein myosin.  A. True B. False Q.17) Interstitial fluid represents one type of extracellular material.

A. True B. False Q.18) Hyperplasia generally means that an organ will increase in size due to the excessive formation of  extracellular fluids.  A. True B. False Q.19) A chemical that inhibits DNA synthesis has yet to be found in aging cells.  A. True B. False Q.20) The cell (plasma) membrane normally contains substantial amounts of cholesterol.  A. True B. False Q.21) Aquaporins are believed to be present in red blood cells and kidney tubules, but very few other cells  in the body.  A. True B. False Q.22) Most organelles are bounded by a membrane that is quite different in structure from the lipid  bilayer of the plasma membrane.  A. True B. False Q.23) Only one cell type in the human body has a flagellum.  A. True B. False Q.24) Microtubules are hollow tubes made of subunits of the protein tubulin.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
