Step 1
How do sunken stomata assist the plant to conserve water in a dry environment?
Answer
Sunken stomata help conserve water in a dry environment primarily by reducing transpiration. They create a microclimate of moist air around the stoma, which decreases the water vapor gradient between the inside of the leaf and the external environment. This ultimately leads to reduced water loss through transpiration, allowing the plant to retain moisture efficiently.
