cell transport

When both the inside and the outside of the cell have the same amount of water and are balanced, the cell has reached

• hypertonic

• equilibrium

• hypotonic

• active transport

this image is an example of _______________

• diffusion

• active transport

• osmosis

• hypertonic

When perfume or air freshener spreads from a high concentration in the bottle to a low concentration in other parts of the house, that's an example of _____________

• active transport

• diffusion

• osmosis

which way will the water molecules move during osmosis?

• into the cell, so the cell shrinks

• into the cell, so the cell swells

• out of the cell, so the cell swells

• out of the cell, so the cell shrinks

which diagram best shows the end result of osmosis?

• a

• b

• c

During osmosis, ______________

• water moves from high to low concentration across a selectively permeable membrane

• proteins are built

• large or oddly shaped molecules move across a cell membrane

• water moves using ATP energy

the picture is an example of ________________

• active transport

• osmosis

• diffusion

passive transport requires ______________

• ATP energy

• no energy

What does "high concentration" mean?

• uncrowded

• tightly packed together

• spread out

What does "selectively permeable" mean?

• the membrane only lets certain substances through

• the membrane lets all substances through

• the membrane allows no substances through
