Answer:
Solution A-It will likely swell up since you put it in a hypotonic solution
Solution B- Since you placed it in a hypertonic solution, its gonna shrivel up and become smaller
Explanation:
Solution A- Placing Elodea cells into 100% water, which is more hypotonic than freshwater, also causes water movement into of the cells resulting in the swelling of the cells. ... As water moves out of the cells there is a loss of turgor pressure and the plasma membranes detach from the cell walls as the cells shrink.
B- When the Elodea was placed in the salt solution, the vacuoles disappeared and the protoplasm came away from the cell wall making the organelles appear to be clumped in the middle of the cell. ... Therefore, if it were placed in a hypertonic solution it would lose water and shrivel.
Hope this helps! Brainliest??Anyways have a great day my loves<3

Examples of active transport are proton pumps, exocytosis and endocytosis.
