Detailed explanation-1: -Correct answer will include the following elements-Water within a plant cell exerts a force against the cell wall called turgor pressure. Turgor pressure allows a plant to maintain a strong, upright position. When a plant does not get the water that it needs, the cells lose their shape and the plant wilts.

Detailed explanation-2: -Please explain how the force of turgor pressure causes a plant to return to its upright position after a period of dehydration. As turgor pressure increases more water is pushed against the cell wall causing the plant to stand up straight.

Detailed explanation-3: -turgor, Pressure exerted by fluid in a cell that presses the cell membrane against the cell wall. Turgor is what makes living plant tissue rigid. Loss of turgor, resulting from the loss of water from plant cells, causes flowers and leaves to wilt.

Detailed explanation-4: -When turgor pressure is low, gravity is a greater force and it pulls the plant down. When seedlings are pushing upward, it has to have a great enough force to push up against gravity which allows it to grow (move) upward. 2.

Detailed explanation-5: -When a plant wilts due to a drought, it is responding to which of the following internal stimuli? Decreased water pressure within the plant cells.
