Biology

greater concentration of solute molecules outside

hypertonic

lower concentration of solute molecules outside

hypotonic

same concentration of solute molecules outside

isotonic

swelling and bursting

hypotonic

shrinking

hypertonic

staying the same size

isotonic

substance that dissolves to make a solution is called

solvent

diffusion tend to move

down

when the concentration of solute inside and outside a cell is the same, the has reached

homeostasis

the diffusion of water across a selectively permeable membrane is called

osmosis

energy for active transport comes from a cell’s

mitochondria

blank transport requires energy from ATP to move substances across membranes

active

all of the following are kinds of passive transport except

ion channels

when molecules move DOWN the concentration gradient it means they’re moving from

an area of high concentration to an area of lower concentration

active transport requires blank to move molecules across membranes

energy

blank is the molecule that provides the energy for active transport

ATP

blank moves oxygen and carbon dioxide molecules from a high concentration to a low concentration across membranes

diffusion

the cell organelles that burns glucose and provides ATP for active transport are the blank

mitochondria

water moves across membranes by blank

osmosis

a small membrane sac used to transport substances during exoocytosis and endocytosis

vacuole

blank transport does not require energy

passive

a cell placed in an blank solution neither swells or shrinks because the concentration between one place and another

isotonic

a solution in which there is a higher concentration of molecules outside the cell than inside

hypertonic

a concentration blank forms whenever there is a difference in concentration between one place and another.

gradient

a solution in which the concentration of molecules outside the cell is lower than outside

hypotonic

when molecules move from high to low along a concentration gradient we say they are moving blank the gradient

down

blank pressure is caused by water inside a plant cell pushing against the cell

turgor

solution with a lower solute concentration (more water)

hypertonic

solution in which the solute concentration is the same

isotonic

condition plant cell require

hypertonic

condition that animal cell require

hypotonic

red blood cell bursts (cytolysis)

hypotonic

plant cells shrink (plasmolysis)

Hypertonic

solution with a higher solute concentration (less water)

hypotonic

solution with a high water concentration

hypertonic

transport protein that provides a tubelike opening in the plasma membrane through which particles can diffuse

Channel protein

is used during active transport but not passive transport

energy

process by which a cell takes in material by forming a vesicle around it

endocytosis

particle movement from an area of higher concentration to an area of lower concentration

passive transport

process by which a cell expels wastes from a vesicle

exocytosis

a form of passive transport that uses transport protiens

facilitated diffusion

particle movement from an area of lower concentration to an area of higher concentration

active transport

repels/hates water

hydrophobic

helps maintain the flexibility of the membrane

cholesterol

involved in cell-to-cell recognition

glycoprotien/carbohydrate chain

attracts/loves water

hydrophilic

helps transport materials (such as glucose) across the membrane

integral protein
