5 Matching questions

  1. cell wall
  2. glycocalyx
  3. plasma membrane
  4. rough endoplasmic reticulum
  5. plastid
  1. a A layer of exopolysaccharide fibers on the surface of bacterial cells which may be involved in adherence to a surface. Sometimes a general term for a bacterial capsules; if compact called capsule and if diffuse, called slime layer
  2. b System of internal membranes within the cytoplasm. Membranes have the presence of ribosomes; functions in transport of substances such as proteins within the cytoplasm
  3. c strong wall outside a plant cell's plasma membrane that protects the cell and maintains its shape
  4. d group of closely related plant organelles that are used for storage of starches, lipids, or pigments; includes chloroplasts, chromoplasts, and amyloplasts (leucoplasts).
  5. e thin outer boundary of a cell composed of a bilayer of phospholipids in which proteins are embedded that regulates the traffic of chemicals between the cell and its surroundings

5 Multiple choice questions

  1. A eukaryotic cell organelle consisting of a 9 + 0 arrangement of microtubule triplets; may organize the microtubule assembly of a cilium or flagellum; structurally identical to a centriole.
  2. a microscopic network of actin filaments and microtubules in the cytoplasm of many living cells that gives the cell shape and coherence
  3. the smallest unit that can perform all life processes; cells are covered by a membrane and contain DNA and cytoplasm
  4. ratio of a cell's outside area to its internal volume
  5. The collection of membranes inside and around a eukaryotic cell, related either through direct physical contact or by the transfer of membranous vesicles; includes the smooth and rough endoplasmic reticulum, the Golgi apparatus, lysosomes, and vacuoles.

5 True/False questions

  1. ribosomemembrane-bound sac containing digestive enzymes that can break down proteins, nucleic acids, and polysaccharides


  2. prokaryotic cellA type of cell lacking a membrane-enclosed nucleus and membrane-enclosed organelles; found only in the domains Bacteria and Archaea.


  3. cristaeInfoldings of the inner membrane of a mitochondrion that houses the electon transport chain and the enzyme catalyzing the synthesis of ATP.


  4. vesiclesmall membrane-bound sac that functions in moving products into, out of, and within a cell


  5. cell theorystrong wall outside a plant cell's plasma membrane that protects the cell and maintains its shape
