UMN BIOL 2003 Midterm 1-Cell
Biology questions and answers
Cell theory - correct answer ✔✔ Cells are derived from preexisting, are the fundamental
structure of life and make up all organisms
Endosymbiosis and mitochondria - correct answer ✔✔ bacterial cell took up residence inside
another cell
Endosymbosis and chloroplasts - correct answer ✔✔ Protist engulfed a cyanobacterium
semiautonomous organelles - correct answer ✔✔ organelles that have their own DNA
nuclear transport - correct answer ✔✔ transport of molecules, usually RNA, in and out of the
nucleus
molecular "zip codes" - correct answer ✔✔ nuclear proteins that mark molecules for transport
Pulse-chase assay - correct answer ✔✔ used to track protein movement
endocytosis - correct answer ✔✔ pinching off the plasma membrane to take up material from
outside the cell
Phagocytosis - correct answer ✔✔ plasma membrane surrounds smaller cell, engulfs it and
destroys it
