5 Written questions

5 Matching questions

  1. nucleus
  2. nuclear envelope
  3. nucleoid
  4. flagellum
  5. plasmodesma
  1. a A long cellular appendage specialized for locomotion. The flagella of prokaryotes and eukaryotes differ in both structure and function. Like cilia, eukaryotic flagella have a 9 + 2 arrangement of microtubules covered by the cell's plasma membrane.
  2. b A dense region of DNA in a prokaryotic cell.
  3. c An open channel in a plant cell wall through which strands of cytoplasm connect from adjacent cells.
  4. d (1) An atom's central core, containing protons and neutrons. (2) The genetic control center of a eukaryotic cell.
  5. e A double membrane, perforated with pores, which encloses the nucleus and separates it from the rest of the eukaryotic cell.

5 Multiple choice questions

  1. A microscope that uses an electron beam to study the internal structure of thinly sectioned specimens.
  2. A microscope that uses an electron beam to study the surface architecture of a cell or other specimen.
  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. A type of cell that has a membrane-enclosed nucleus and other membrane-enclosed organelles. All organisms except bacteria and archaea are composed of eukaryotic cells.
  5. A macromolecule consisting of one or more polypeptides linked to short chains of sugars.

5 True/False questions

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

          

  2. endomembrane systemA process by which the mitochondria and chloroplasts of eukaryotic cells probably evolved from symbiotic associations between small prokaryotic cells living inside larger cells.

          

  3. electron microscope (EM)An instrument that focuses an electron beam through, or onto the surface of, a specimen. An electron microscope achieves a hundredfold greater resolution than a light microscope.

          

  4. endoplasmic reticulum (ER)An instrument that focuses an electron beam through, or onto the surface of, a specimen. An electron microscope achieves a hundredfold greater resolution than a light microscope.

          

  5. centrioleA 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.
