What best describes the cell membrane?
It is a single layer of lipids.
It is an impenetrable barrier.
It is strong, rigid and durable.
It is a lipid bilayer.
When a plant cell is placed in a saltwater solution, the cell is affected and changes size. What part of the cell will be unaffected?
The cell membrane
The cytoplasm
The cell wall
The vacuole
Which cell process moves substances against a concentration gradient?
diffusion
facilitated diffusion
osmosis
active transport
What molecule is used as energy for active transport?
ADP
ATP
lipase
glucose
Which type of cell transport occurs when a cell's membrane folds inward to bring material into the cell?
endocytosis
pinocytosis
exocytosis
phagocytosis
What type of protein helps molecules move through a cell membrane?
channel protein
carrier protein
receptor protein
glycoprotein
What is the main function of a selectively permeable cell membrane?
storage of water
break down of molecules in the cell
storage of chemicals
regulates what enters and leaves the cell
What is the difference between diffusion and facilitated diffusion?
facilitated diffusion requires energy
diffusion moves substances from low to high concentration
facilitated diffusion uses carrier proteins to move substances in or out of the cell
all of the above
What type of membrane protein has a straight pathway for molecules to move?
channel protein
carrier protein
receptor protein
glycoprotein
What ions does this carrier protein pump from low to high concentration?
calcium & iron
nitrogen & sodium
sodium & potassium
potassium & calcium
Which is an example of osmosis?
water moving into the root cells of a plant
oxygen moving into the bloodstream from the lungs
potassium ions moving in and out of an animal cell
all of the above
Two solutions that have the same solute concentration is called _________.
osmosis
hypertonic
hypotonic
isotonic
A solution with a higher concentration of solutes than that of the cell is called _________.
osmosis
hypertonic
hypotonic
isotonic
What would happen to a cell placed in a hypotonic solution?
water would move out of the cell causing it to shrink
salt would move out of the cell causing it to shrink
water would move into the cell causing it to swell
the cell would remain the same size
What type of transport occurs when a large cell consumes a smaller cell such as a bacterium?
endocytosis
pinocytosis
exocytosis
phagocytosis
What transport occurs when fluid and solute is ingested into a cell by budding of small vesicles from the cell membrane?
endocytosis
pinocytosis
exocytosis
phagocytosis
How does particle size affect a molecule's ability to move across a cell membrane?
It is easier for small molecules to diffuse across the cell membrane.
It is easier for large molecules to diffuse across the cell membrane.
Particle size is not important.
Particle size is not as important as shape when moving across the membrane.
