5 Written questions

5 Matching questions

  1. actin filament
  2. mesosome
  3. plastid
  4. nucleolus
  5. intermediate filament
  1. a group of closely related plant organelles that are used for storage of starches, lipids, or pigments; includes chloroplasts, chromoplasts, and amyloplasts (leucoplasts).
  2. b rope-like assemblies of fibrous polypeptides in the cytoskeleton that provide support and strength to cells; A component of the cytoskeleton that includes all filaments intermediate in size between microtubules and microfilaments.
  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 plasma membrane that folds into the cytoplasm and increases surface area
  5. e The organelle where ribosomes are made, synthesized and partially assembled, located in the nucleus

5 Multiple choice questions

  1. membrane-bound sac that buds from the endoplasmic reticulum or the Golgi apparatus, storage structures for food, water, minerals, waste
  2. A temporary, foot-like extension of a cell, used for locomotion or engulfing food
  3. in a bacterium, stored nutrients for later use
  4. Region in prokaryotic cell where DNA is concentrated, not enclosed by membrane
  5. strong wall outside a plant cell's plasma membrane that protects the cell and maintains its shape

5 True/False questions

  1. Golgi apparatusA stacked portion of the thylakoid membrane in the chloroplast; functions in the light reactions of photosynthesis.

          

  2. chromosomeA threadlike linear strand of DNA and associated proteins in the nucleus of eukaryotic cells that carries the genes and functions in the transmission of hereditary information

          

  3. prokaryotic cellA type of cell with a membrane-enclosed nucleus and membrane-enclosed organelles. Examples of organisms with these cells are protists, plants, fungi, and animals; organisms are in the Eukarya domain

          

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

          

  5. smooth endoplasmic reticulumA network of membranes inside eukarytoic cells invovled in lipid synthesis (steroid in gonads), detoxification (in liver cells), and/or Ca2+ storage (muscle cells); lacks ribosomes on the surface
