Effects of Sunlight on Plants

The video tutorial reviews key concepts about water reservoirs on Earth, including oceans, lakes, and the atmosphere. It explains the water cycle processes like evaporation and precipitation, driven by the Sun's energy. An experiment is conducted to observe water transpiration in plants under sunlight and shade, demonstrating the effect of energy on water movement. The tutorial concludes by linking air movement to the water cycle, emphasizing the role of thermal energy in transforming water into vapor.

Which of the following is NOT considered a reservoir of water on Earth?

• Lakes

• Mountains

• Oceans

• Atmosphere

What is the primary source of energy that drives the water cycle?

• The Moon

• Gravity

• The Sun

• Wind

In the plant experiment, why is one plant placed in direct sunlight?

• To measure the growth rate of the plant

• To test the plant's resistance to heat

• To observe the effect of sunlight on transpiration

• To see how sunlight affects leaf color

What is the expected outcome for the plant placed in direct sunlight?

• The leaf will grow larger

• The leaf will remain unchanged

• The leaf will turn green

• Water will form inside the plastic bag

How does air movement relate to the water cycle?

• Air movement helps water vapor move from one place to another

• Air movement has no effect on the water cycle

• Air movement causes water to freeze

• Air movement only affects the temperature of water
