5 Written questions

5 Matching questions

  1. mitochondrial matrix
  2. Reverse Transcriptase
  3. microtubule
  4. Vesicle
  5. endomembrane system
  1. a A network of membranes inside and around a eukaryotic cell, related either through direct physical contact or by the transfer of membranous vesicles.
  2. b The fluid contained within the inner membrane of a mitochondrion.
  3. c A sac made of membrane in the cytoplasm of a eukaryotic cell.
  4. d Makes RNA into DNA
  5. e The thickest of the three main kinds of fibers making up the cytoskeleton of a eukaryotic cell; a straight, hollow tube made of globular proteins called tubulins. Microtubules form the basis of the structure and movement of cilia and flagella.

5 Multiple choice questions

  1. A stack of hollow disks formed of thylakoid membrane in a chloroplast. Grana are the sites where light energy is trapped by chlorophyll and converted to chemical energy during the light reactions of photosynthesis.
  2. An organelle in eukaryotic cells where cellular respiration occurs. Enclosed by two concentric membranes, it is where most of the cell's ATP is made.
  3. An infolding of the inner membrane of a mitochondrion in which is embedded the electron transport chain and the enzyme catalyzing the synthesis of ATP.
  4. The chemical activities of cells.
  5. The complex of DNA and proteins that constitutes eukaryotic chromosomes; often used to refer to the diffuse, very extended form taken by chromosomes when a cell is not dividing.

5 True/False questions

  1. flagellumA structure within the nucleus of a eukaryotic cell where ribosomal RNA is made and assembled with proteins imported from the cytoplasm to make ribosomal subunits.

          

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

          

  3. extracellular matrix (ECM)A substance in which the cells of an animal tissue are embedded; consists of protein and polysaccharides.

          

  4. transmission electron microscopeA microscope that uses an electron beam to study the surface architecture of a cell or other specimen.

          

  5. light microscope (LM)An optical instrument with lenses that refract (bend) visible light to magnify images and project them into a viewer's eye or onto photographic film.
