Worked Solution

Step 1: Plants take in water from the soil. Step 2: They use some for photosynthesis, but excess water is given off. Step 3: This process is called transpiration, where water vapour is released through stomata on the leaves into the atmosphere, contributing to the water cycle.

Correct answer: They release water vapour through their leaves into the air.
