In a hypertonic solution, water moves (in/out) of the elodea cell.

the answer is

while the heads of the phospholipid structure attract water, the tails are hydrophobic. the model shows how the hydrophilic section folds around the fluid molecules to bring them into the cell so they don’t need to pass through the hydrophobic tails.  

it can affect the plants by how hot or cold the temperature

explanation:

it can affect the plants by how hot or cold the temperature is and the amount of precipitation can affect the plants cause it needs to have reasonable amount
