Turgor Pressure, Stimulus and Response Practice

Which of the following is an example of a plant responding to the stimulus of gravity?

• A seedling growing towards a sunny window

• Plant roots growing down into the soil

• Flowers producing nectar to attract bees

• A potted plant wilting when it dries out

The illustration shows a plant cell after one week without water. Which of the following describes the plant’s response as a result of the stimuli of the lack of water?

• Lack of water causes plant cells to expand.

• Lack of water causes plant cells to have turgidity.

• Lack of water causes plants to lose turgor pressure resulting to wilting

• Lack of water causes turgor pressure to increase resulting to shrinking of the plant cells.
