This increase in the plant cell as water moves in keeping the plant erect but prevents it from bursting. A. Exocytosis B. Gradients C. Turgid pressure D. Diffusion

The change is caused by C. Turgid pressure

Explanation:

Turgor pressure, is exerted internally by the plants own cells. The water in the plant moves from areas of  high concentration to areas of low concentration along a concentration gradient.

The cells contain large organelles called vacuoles, which are filled with water, salts and other substances contained in cell sap. The large vacuole takes up most of the cell, and pushes against the cell walls. This exerted pressure keeps the cell's shape, and ensure that the tissues stay upright.
