Observe the two plants. Which cellular change affected the structure of second plant?
OLEGan [10]

Answer:

The correct answer is option D which is release of water from the vacuoles.

Vacuoles are present in the center of plant cell. They are usually filled with water and provide structural support to the cell.

In the absence of water filled vacuoles, plants shoots are wilted as in case of second plant.
