A plant that is wilted is said to have . . .

• High turgor pressure

• Medium turgor pressure

• Low turgor pressure

• Negative homeostasis

This force is created by water filling up the vacuoles, and gives a plant rigidity and shape so that it does not wilt.

• Photosynthesis

• Respiration

• Turgor Pressure

• Tropism

What do you do when you see your plant like this?

• Nothing, it's fine

• Water it because it has high turgor pressure

• Water it because it has low turgor pressure

• Breathe carbon dioxide into it
