Dylan is doing a science experiment on the stomata of plants. Dylan has a tomato plant. He uses wax to cover all the stomata on the leaves of the plant. After five days, Dylan observes that the plant is wilting. What is the best explanation for Dylan's observation?

• The plant released too much water into the air.

• The plant was unable to carry out transpiration.

• Condensation could not occur on the leaves of the plant.

• The plant was unable to take in water through its leaves.

Taylor grows plants in a container called a terrarium. She keeps the terrarium on a sunny windowsill.

The terrarium is closed, so Taylor cannot add water to the plants. However, the plants have enough water to grow. Which of these statements best explains why the plants always have enough water?

• The air cannot hold all of the water vapor.

• Water is unable to evaporate from the soil.

• Energy from the sun cycles water through the soil, the plants, and the air.

• The plants take up water and store it in their stems and leaves.

Which of these changes of state would involve water absorbing energy?

• condensation

• deposition

• evaporation

• freezing

Which statement best describes the movement of liquid water from land back into a body of water?

• condensation

• evaporation

• precipitation

• runoff

In which form does water rise into the atmosphere when it evaporates?

• water vapor

• water droplets

• snow

• ice

Which term best describes a change of state from a liquid to a gas caused by the sun's energy?

• evaporation

• sublimation

• deposition

• precipitation
