All
living things need water to stay alive, and plants are living things! Plants,
however, need much more water than many living things because plants use much
more water than most animals. Plants also contain more water than animals -
plants are about 90% water. The amount of water a plant needs depends on the
type of plant, how much light the plant gets, and how old the plant is. When
plants are not watered properly they wilt. This is because of something called
turgor, which is water pressure inside the cells that make up the plant's
skeleton. Water enters a plant through its stem and travels up to its leaves.
When a plant is properly hydrated, there is enough water pressure to make the
leaves strong and sturdy; when a plant doesn't get enough water, the pressure
inside the stems and leaves drops and they wilt.
