Terms from Modern Biology word jumble worksheet

QuestionAnswer
PLASMOLYSIS (1)THE CONTRACTION OR SHRINKING OF A CELL IN A HYPERTONIC SOLUTION IN RESPONCE TO THE LOSS OF WATER BY OSMOSIS
CYTOLYSIS (2)THE BURSTING OF A CELL
ION CHANNEL (3)A COMPLEX OF PROTEIN MOLECULES IN A CELL MEMBRANE THAT FORM A PORE THROUGH WHICH IONS CAN PASS.
ACTIVE TRANSPORT (4)THE MOVEMENT OF CHEMICAL SUBSTANCES USUALLY ACROSS THE CELL MEMBRANE, AGAINST A CENCENTRATION GRADIENT, REQUIRES CELLS TO USE ENERGY
HYPERTONIC (5)DESCRIBES A SOLUTION WHOSE SOLUTE CONCENTRATION IS HIGHER THAN THE SOLUTE CONCENTRATION INSIDE A CELL
CARRIER PROTEIN (6)A PROTEIN THAT TRANSPORTS SUBSTANCES ACROSS A CELL MEMBRANE
DIFFUSION (7)THE MOVEMENT OF PARTICLES FROM REGIONS OF HIGHER DENSITY TO REGIONS OF LOWER DENSITY
OSMOSIS (8)THE DIFFUSION OF WATER FROM A MORE DILUTE SOLUTION TO A MORE CONCENTRATED SOLUTION THROUGH A MEMBRANE
TURGOR PRESSURE (9)THE PRESSURE THAT IS EXERTED ON THE INSIDE OF CELL WALLS AND THAT IS CAUSED BY THE MOVEMENT OF WATER INTO THE CELL
HYPOTONIC (10)DESCRIBES A SOLUTION WHOSE SOLUTE CONCENTRATION IS LOWER THAN THE SOLUTE CONCENTRATION INSIDE A CELL
CONCENTRATION GRADIENT (11)A DIFFERENCE IN THE CONCENTRATION OF A SUBSTANCE ACROSS A DISTANCE
EQUILIBRIUM (12)IN BIOLOGY, THE STATE THAT EXISTS WHEN THE CONCENTRATION OF A SUBSTANCE IS THE SAME THROUGOUT A SPACE
FACILITATED DIFFUSION (13)THE TRANSPORT OF SUBSTANCES THROUGH A MEMBRANE ALONG A CONCENTRATION GRADIENT WITH THE AID OF CARRIER PROTEINS
CONTRACTILE VACUOLE IN PROTISTS, AN ORGANELLE THAT ACCUMULATES (14)WATER AND THEN RELEASES IT PERIDICALLY TO MAINTAIN OSMOTIC PRESSURE
ISOTONIC (15)DESCRIBES A SOLUTION WHOSE SOLUTE CONCENTRATION IS EQUAL TO THE SOLUTE CONCENTRATION INSIDE A CELL
SODIUM-POTASSIUM PUMP (16)A CARRIER PROTEIN THAT USES ATP TO ACTIVELY TRANSPORT SODIUM IONS OUT OF A CELL AND POTASSIUM IONS INTO THE CELL
PASSIVE TRANSPORT (17)THE MOVEMENT OF SUBSTANCES ACROSS A CELL MEMBRANE WITHOUT THE USE OF ENERGY BY THE CELL
PHAGOCYTE (18)A CELL THAT INGESTS AND DESTROYS (DIGESTS)FOREIGN MATTER OR MICROORGANISMS
ENDOCYTOSIS (19)THE PROCESS BY WHICH A CELL MEMBRANE SURROUNDS A PARTICLE AND ENCLOSES THE PARTICLE IN A VESICLE TO BRIN THE PARTICLE INTO THE CELL
EXOCYTOSIS (20)THE PROCESS BY WHICH A SUBSTANCE IS RELEASED FROM THE CELL THROUGH A VESICLE THAT FUSES WITH THE MEMBRANE TO LET THE SUBSTANCE OUT
