AP BIOLOGY TEST: CELLS
QUESTIONS AND ANSWERS
cells - Correct Answers -the smallest unit of living material that can carry out all the
activities necessary for life
light microscopes/compound microcopes - Correct Answers -used to study stained or
living cells, can magnify up to 1000 times
electron microscopes - Correct Answers -used to study detailed structures of a cell, can
magnify up to 250,000 times, only for dead cells
eukaryotic cells - Correct Answers -contains a membrane bound nucleus and organelles
prokaryotic cells - Correct Answers -lacks a nucleus and membrane bound organelles
nucleoid - Correct Answers -the are where the genetic material of a prokaryotic cells lies
organelles - Correct Answers -little organs that live in cells with specific tasks
plasma membrane - Correct Answers -a double-layered structure that serves as a
selectively permeable outer envelope of a eukaryotic cell
peripheral proteins - Correct Answers -proteins that lay are on the inner or outer surface
of the lipid bilayer
integral proteins - Correct Answers -proteins firmly bound to the plasma membrane that
extend from one end of the lipid bilayer to the other

that make up the membrane of eukaryotic cell
adhesion proteins - Correct Answers -membrane proteins that form junctions between
adjacent cells
receptor proteins - Correct Answers -membrane proteins that serve as docking sites fr
proteins of the extracellular matrix or hormones
