cellular organelles - ANSWERtypically work in coordination with other organelles to accomplish and
overall cellular activity.
selectively permeable - ANSWERproperty of biological membranes that allows some substances to pass
across it while others cannot; also called semipermeable membrane
G1 phase - ANSWERThe first gap, or growth phase, of the cell cycle, consisting of the portion of
