Answer:

C

Explanation:

This is placing a cell in hyper tonic solution.Therefore, the water potential of the cells is higher than the environment. Hence it lose water to the environment which has a  lower water potential, but higher solute potential.

Therefore the loss of fluid by the cell leads to shrinking of the cytosol and it containing organelles. Later the cells collapse.

<u>Spanish</u>

Esto es colocar las células en una solución hipertónica. Por lo tanto, el potencial hídrico de las células es mayor que el del medio ambiente. Por lo tanto, perder agua al medio ambiente reducirá el potencial hídrico, pero aumentará el potencial de soluto.

Por lo tanto, la pérdida de líquido por parte de la célula conduce a la contracción del citosol y que contiene orgánulos.
