AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
The loss of water in the form of vapour from the aerial parts of the plant is called transpiration.
This is a direct fill-in-the-blank question worth 1 mark. The examiner expects only the term "transpiration." It is related to the topic of stomata and water loss in plants covered in Chapter 5 (Life Processes). Remember: transpiration occurs mainly through stomata present on leaves and other aerial parts.
