6. Name of things which gravitate towards opposite ends of cell during mitosis/ meiosis to aid cell division.

  • Lysosomes
  • Reticula
  • Centrioles
  • Mitochondria

7. Which thing is not exclusive to plant cells?

  • Chloroplasts containing stroma (sites of light-independent photosynthetic reactions)
  • Cellulose cell wall for structural integrity
  • Grana (stack of thylakoid membranes, the sites of light-dependent photosynthetic reactions)
  • Cell membrane comprised of a phospholipid bilayer
  • Sap-filled vacuole for chemical storage and water level adjustment

8. Name of the series of folded phospholipid membranes that are rough or smooth, depending on whether they have embedded ribosomes or are for the synthesis of lipids.

  • Mitochondria
  • Endoplasmic reticula
  • Golgi apparatus
  • Polypeptide chains

9. Name of thing that stores highly condensed DNA around histone proteins; messenger RNA comes out of its little pores and nucleotides go in. It is equipped with a nucleolus in which RNA and ribosomes are manufactured.

  • Golgi body
  • Reticulum
  • Nucleus
  • Centriole

10. Fundamental difference between eukaryotic and prokaryotic cells?

  • Eukaryotic cells have membrane-bound organelles; prokaryotes do not. Also prokaryotic cells store DNA either in a nucleoid (single, circular chromosome), or as plasmid DNA,, instead of in a nucleus.
  • Prokaryotic cells have membrane-bound organelles; eukaryotic cells do not. Also prokaryotic cells store DNA in a nucleus; eukaryotic cells do not).

11. The site of all metabolic reactions in prokaryotic cells?

  • Crykokasm
  • Tribovagm
  • Cytoplasm
  • Flitoblasm

12. In microscopy, what is the equation ‘size of image divided by size of object’?

  • Magnification
  • Eyepiece magnification
  • Overall magnification

13. Which is not a type of virus?

  • Spherical
  • Tobacco mosaic
  • Bacteriophage
  • Polyhedral
  • Complex
  • Cellular
  • Helical

14. If endocrine is the long distance intercellular signalling using hormones, what is paracrine?

  • Long distance using proteins
  • Local cell signalling
  • Long distance using electrical impulses

15. Things used by bacterial cell to swim around and to adhere to surfaces like host cell membranes.

  • Cell wall and fimbriae
  • Flagella and fimbriae
  • Flagella and cell wall
  • Capsule and ribosomes

16. Name of thing which is the site of aerobic respiration; ATP-generating reactions happen in its inner matrix.

  • Mitochondria
  • Centrioles
  • Nucleus
  • Cytoplasm

17. In microscopy, what is the equation ‘objective magnification x eyepiece magnification?

  • Size of image
  • Overall magnification
  • Size of object

18. Which of the following is not part of a virus’ structure, but is in fact found on the surface of the host cell?

  • Polypeptide coat called a capsid
  • Surface marker proteins
  • DNA/RNA
  • Attachment proteins to aid access.

19. What is indicated about a cell wall if it is Gram positive?

  • It is big enough to absorb a lot of Gram stain
  • It is small enough to absorb very little Gram stain

20. Which job is not something provided by a bacterial cell’s capsule

  • Helping cell adhere to surfaces
  • Aiding movement through various mediums.
  • Defending cell from phagocytes
  • Ultimately making the cell more virulent.
