5 Matching questions

  1. matrix
  2. lysosome
  3. actin filament
  4. chromoplast
  5. granum
  1. a A stacked portion of the thylakoid membrane in the chloroplast; functions in the light reactions of photosynthesis.
  2. b type of plastid that synthesizes and stores red, yellow, and orange pigments, responsible for colors of many fruits and flowers
  3. c muscle protein filament in a sarcomere; its movement shortens the sarcomere, yielding muscle contraction. Actin filaments play a role in the movement of the cell and its organelles
  4. d membrane-bound sac containing digestive enzymes that can break down proteins, nucleic acids, and polysaccharides
  5. e unstructured semifluid substance that fills the space between cells in connective tissues or inside organelles, the surface area exposed to fluids, such as where the production of energy takes place, in a mitochondrion

5 Multiple choice questions

  1. strong wall outside a plant cell's plasma membrane that protects the cell and maintains its shape
  2. the smallest unit that can perform all life processes; cells are covered by a membrane and contain DNA and cytoplasm
  3. one of the small bodies that are found in the cytoplasm of a cell and that are specialized to perform a specific function
  4. elongated, hollow appendages that pull 2 cells together prior to DNA transfer from one cell to the other found in bacterium
  5. small membrane-bound sac that functions in moving products into, out of, and within a cell

5 True/False questions

  1. cyanobacteriaunstructured semifluid substance that fills the space between cells in connective tissues or inside organelles, the surface area exposed to fluids, such as where the production of energy takes place, in a mitochondrion

          

  2. leucoplastColorless plastids that synthesize and store starches and oils

          

  3. plasmida circular DNA molecule that is usually found in bacteria and that can replicate independent of the main chromosome

          

  4. spirillumA type of bacterial cell with a rigid spiral shape and external flagella.

          

  5. flagelluma lash-like appendage used for locomotion (e.g., in sperm cells and some bacteria and protozoa)
