The release of water from the of the cells caused the plant to wilt and droop. The in the plant's cells helps the plant to maintain its structure during this period of stress.

Vacuoles are the first blank, while cell membrane is the second blank.

Explanation:

The release of water from the vacuoles causes a plant to wilt and droop; if the cells do not contain any water, the plant will wilt and droop.

Vacuoles are enclosed compartments in the solution that are filled with water, inorganic-organic compounds, and enzymes. It's a crucial organelle in the cell of a plant.

The cell wall, on the other hand, aids in the plant's structural preservation during times of stress.

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.
