BMS 110 EXAM 1 QUESTIONS WITH ACCURATE
ANSWERS
active transport correct answer Solutes are made to cross plasma membranes
against their own
Centriole correct answer Microtubule organizing center
centrosome correct answer microtubule that contains spindle fibers to attach to
chromosomes
cilia correct answer Microtubule extension, shorter, more numerous and
functions to "sweep debris"
Concentration Gradient correct answer Difference in the number of molecules or
ions of a given substance in two neighboring regions
cytoplasm correct answer Semifluid matrix of the cell
Cytoskeleton correct answer Help organize and reinforce the cell
Diffusion correct answer Net movement of like molecules or ions from an area of
higher concentration to an area of lower concentration
electric gradient correct answer Difference in electric charge across a plasma
membrane
, electrons correct answer The negative particles in an atom found in orbitals
surrounding the nucleus
endocytosis correct answer Literally means "coming inside the cell"
exocytosis correct answer A vesicle moves to the plasma membrane and fuses
with it, releasing its contents to the outside of the cell
Facilitated diffusion correct answer Solutes diffuse across a plasma membrane
through a transport protein down their own concentration gradients
Flagella correct answer Microtubule extension; found on animal sperm cell
Golgi Body correct answer UPS, functions in processing sorting and packaging
proteins and lipids
Lysosome correct answer contains enzymes to digest other vesicles, worn-out cell
parts or bacteria and foreign particles
Mass correct answer The amount of "substance in an object
Mitochondria correct answer Powerhouse;found in eukaryotic Cells
Neutrons correct answer the neutral particles in the atomic nucleus
