and their function LATEST
QUESTIONS AND VERIFIED
CORRECT ANSWERS
Flagella - CORRECT ANSWER-whiplike tails found in one-celled organisms to aid in
movement,acts as propeller that pushes cell forward
Microvilli - CORRECT ANSWER-Fingerlike extensions of plasma membrane that aids in
absorption
Channels - CORRECT ANSWER-Allows ions to free flow in and out
Receptors - CORRECT ANSWER-parts of the cell membrane that receive the neurotransmitter
and initiate or prevent a new electric signal
passive transport - CORRECT ANSWER-Requires NO energy, Movement of molecules from high
to low point with processes such as diffusion, osmosis,dialysis, and filtration
active transport - CORRECT ANSWER-Energy-requiring process that moves from low point to
high point
Diffusion - CORRECT ANSWER-Movement of particles from an area of higher concentration to
an area of lower concentration.
, Osmosis - CORRECT ANSWER-Water Moves from low to high solute concentration
Filtration - CORRECT ANSWER-water and particles being forced against pressure. move from
area of high pressure to low pressure
Hypotonic - CORRECT ANSWER-From outside to inside, moves water in-particles out causes cell
to swell
Hypertonic - CORRECT ANSWER-Moves water from inside cell to outside, cell shrinks
Isotonic - CORRECT ANSWER-Equal number of water and particles in and out of cell
Phagocytosis (endocytosis) - CORRECT ANSWER-"Cell eating"; movement of cells or large
particles into a cell by trapping it
Pinocytosis (endocytosis) - CORRECT ANSWER-Cell drinking movement of fluid or dissolved
molecules into cell by trapping it
Exocytosis - CORRECT ANSWER-Movement of protein or other cell products out of cell by fusing
vesicle with the plasma membrane
Mitosis - CORRECT ANSWER-growth and repair- cell reproduction
Meiosis - CORRECT ANSWER-Sex cell reproduction
Mitosis steps - CORRECT ANSWER-prophase, metaphase, anaphase, telophase
Prophase - CORRECT ANSWER-Chromatin condenses into Chromosomes, nucleus disappears
