Water is important to plant cells because it is used as one of the reactants in the process of photosynthesis. what is another reason why water is important to plant cells?
a.) water can be used as a substitute for glucose in times of distress.
b.) water to maintain turgidity in plant cells.
c.) water is a major structural component found in plant cell walls.
d.) water signals plant dna to start transcription and translation.

B.) Water helps to maintain turgidity in plant cells.

Turgidity can be defined as the amount of water that is required to make water to exert internal force from inside the plant cell. This is called as turgor pressure it exerts the pressure on the plasma membrane against the cell wall. This process maintains the rigidity inside the plant cell and cells exert external turgor pressure on the neighboring cells that creates a tension, which allows plants to stand erect. Without the amount of appropriate water, the plant cells will collapse and plants will be wilted.  

Therefore, water helps to maintain turgidity in plant cells is an important property of plant cells.

True, Humans have impacted the rainforests through mining, agriculture, and construction. The Earth's history has had a significant effect on the characteristics of its organisms and biomes.
