5 Written questions

5 Matching questions

  1. chromatin
  2. intermediate filament
  3. crista
  4. cytoplasm
  5. Transport vesicle
  1. a A tiny membranous sac in a cell's cytoplasm carrying molecules produced by the cell. The vesicle buds from the endoplasmic reticulum or Golgi and eventually fuses with another membranous organelle or the plasma membrane, releasing its contents.
  2. b An intermediate-sized protein fiber that is one of the three main kinds of fibers making up the cytoskeleton of eukaryotic cells. Intermediate filaments are ropelike, made of fibrous proteins.
  3. c 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.
  4. d 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.
  5. e Everything inside a cell between the plasma membrane and the nucleus; consists of a semifluid medium and organelles.

5 Multiple choice questions

  1. An organelle in eukaryotic cells consisting of stacks of membranous sacs that modify, store, and ship products of the endoplasmic reticulum.
  2. A threadlike, gene-carrying structure found in the nucleus of a eukaryotic cell and most visible during mitosis and meiosis; also, the main gene-carrying structure of a prokaryotic cell. Chromosomes consist of chromatin, a combination of DNA and protein.
  3. A network of membranes inside and around a eukaryotic cell, related either through direct physical contact or by the transfer of membranous vesicles.
  4. 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.
  5. A sac made of membrane in the cytoplasm of a eukaryotic cell.

5 True/False questions

  1. micrographA photograph taken through a microscope.

          

  2. lysosomeA cell structure consisting of RNA and protein organized into two subunits and functioning as the site of protein synthesis in the cytoplasm. The ribosomal subunits are constructed in the nucleolus.

          

  3. stromaA digestive organelle in eukaryotic cells; contains hydrolytic enzymes that digest the cell's food and wastes.

          

  4. glycoproteinA macromolecule consisting of one or more polypeptides linked to short chains of sugars.

          

  5. granumAn infolding of the inner membrane of a mitochondrion in which is embedded the electron transport chain and the enzyme catalyzing the synthesis of ATP.
