Bio exam 2025 ACTUAL QUESTIONS AND
CORRECT ANSWERS
Hypotonic solution - Correct answers✔The solution has a lower solute concentration than the
cell.
Hypertonic solution - Correct answers✔The solution has a higher solute concentration than the
cell.
Isotonic solution - Correct answers✔The solution has the same solute concentration as the cell.
Lyse - Correct answers✔To break open a cell.
Net movement - Correct answers✔The overall movement of a substance from one area to
another.
Turgor pressure - Correct answers✔The pressure exerted by the cell contents against the cell
wall.
Passive Transport - Correct answers✔Movement of molecules across the membrane without
energy input.
Diffusion - Correct answers✔Movement of molecules from an area of high concentration to an
area of low concentration.
, Osmosis - Correct answers✔Movement of water across a semipermeable membrane from an area
of high water concentration to an area of low water concentration.
Facilitated Transport - Correct answers✔Movement of molecules across the membrane with the
help of membrane proteins (channels or carriers) without energy input.
Active Transport - Correct answers✔Movement of molecules against their concentration
gradient, requiring energy (ATP).
