Guttation differs from transpiration mainly because guttation releases
ACarbon dioxide through stomata during the day
BWater vapour through stomatal pores in leaves
CLiquid water from leaf margins through hydathodes
DOxygen during photosynthesis from chloroplasts
Answer & Solution
Correct answer: C. Liquid water from leaf margins through hydathodes
1. The chapter contrasts vapour-loss (transpiration) with liquid drops (guttation).
2. Guttation pushes liquid water out of hydathodes at leaf margins.
3. It happens at high root pressure when air is humid.
4. So option A is correct.
