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).
