Bio 210 Lab Quiz
Maintain separation between the inside of the cell and the outside world - answer cell
membrane function
mosaic (meaning of term) - answer proteins and other molecules are attached to and
embedded in the membrane
brownian movement - answer constant movement of molecules (to maintain equilibrium)
tonicity - answerability of water to change the shape of a cell when placed in solution
hypertonic solution - answer more solute than solvent
hypotonic solution - answer more solvent than solute
isotonic solution - answer equal parts solute and solvent
prophase - answer chromosomes prepare to divide; nuclear envelope disintegrates;
asters become visible (2 pairs of centrioles that begin to form the mitotic spindle)
metaphase - answer chromosomes line up in the middle; asters and mitotic spindle are
visible
anaphase - answerchromosomes pull apart; cleavage furrow forms in late anaphase
telophase - answerchromosomes form 2 nuclei; chromosomes uncoil, nuclear
membrane is re-formed, and the spindle disassembles; cytokinesis continues until 2
cells are formed; CYTOKINESIS AND TELOPHASE END SIMULTANEOUSLY
cytosol - answerprovides the fluid medium necessary for biochemical reactions
organelles - answermembrane enclosed bodies that carry out unique functions
cytoplasm - answerorganelles and cytosol
rough ER - answerstudded with ribosomes (the sites of protein synthesis)
smooth ER - answersynthesizes phospholipids, steroid hormones; regulations cellular
Ca++ concentration; metabolizes carbs; breaks down certain toxins
ribosome - answer2 ribosomal RNA subunits that wrap around mRNA to start the
process of translation, followed by protein synthesis
