What do we call the phenomena where plants lose water to the atmosphere?

• A. Condensation
• B. Evaporation
• C. Transpiration
• D. Precipitation

Answer: (C)

The phenomenon where plants lose water to the atmosphere is known as transpiration. During transpiration, water is absorbed by the plant roots from the soil, moves through the plant, and is released as water vapor through small openings in the leaves called stomata. This process is essential for the plant's ability to regulate temperature and maintain nutrient flow.

Transpiration also contributes to the water cycle by adding moisture to the atmosphere, which can lead to cloud formation and precipitation. While condensation refers to the process of water vapor turning into liquid water, evaporation describes the transformation of liquid water into vapor. Precipitation involves water falling from the atmosphere to the ground, such as rain or snow. Transpiration is specifically related to the action of plants losing water, making it the correct term.
