Which observations match the named cell transport process? Select all that apply.
AWater crosses a selectively permeable membrane by osmosis.✓ Correct
Osmosis concerns solvent movement through a selectively permeable membrane.
BA cell takes in droplets using vesicles by endocytosis.✓ Correct
Endocytosis brings material into a cell in vesicles.
CA cell releases secretory vesicles by exocytosis.✓ Correct
Exocytosis moves secretory vesicles outward.
DFiltration moves material through a membrane without pressure.✗ Incorrect
Filtration uses pressure.
EActive transport moves solute against a gradient without energy.✗ Incorrect
Moving against the gradient by active transport requires energy.
Answer
A. Water crosses a selectively permeable membrane by osmosis. · B. A cell takes in droplets using vesicles by endocytosis. · C. A cell releases secretory vesicles by exocytosis.
Rationale
Cells have distinct mechanisms for moving substances. Water movement, vesicle uptake and vesicle release correspond to osmosis, endocytosis and exocytosis respectively.
RememberMatch transport to the material, direction, and driving mechanism.
