5 Matching questions

  1. microtubule
  2. sex pili
  3. vacuole
  4. plastid
  5. smooth endoplasmic reticulum
  1. a A hollow rod of tubulin protein in the cytoplasm of all eukaryotic cells and in cilia, flagella, and the cytoskeleton.
  2. b A 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
  3. c group of closely related plant organelles that are used for storage of starches, lipids, or pigments; includes chloroplasts, chromoplasts, and amyloplasts (leucoplasts).
  4. d elongated, hollow appendages that pull 2 cells together prior to DNA transfer from one cell to the other found in bacterium
  5. e membrane-bound sac that buds from the endoplasmic reticulum or the Golgi apparatus, storage structures for food, water, minerals, waste

5 Multiple choice questions

  1. strong wall outside a plant cell's plasma membrane that protects the cell and maintains its shape
  2. 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.
  3. opening in the nuclear envelope that permits the passage of proteins into the nucleus and ribosomal subunits out of the nucleus
  4. the smallest unit that can perform all life processes; cells are covered by a membrane and contain DNA and cytoplasm
  5. any spherical or nearly spherical bacteria

5 True/False questions

  1. chromatinA 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

          

  2. lysosomesmall particle in the cell on which proteins are assembled; made of RNA and protein

          

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

          

  4. central vacuoleA structure in an animal cell composed of cylinders of microtubule triplets arranged in a 9 + 0 pattern. An animal cell usually has a pair of centrioles involved in cell division.

          

  5. matrixan area within a chloroplast that lies between the thylakoid membranes; serves as the site of the Calvin cycle in photosynthesis which involves the synthesis of carbohydrates
