Which plant has **epistomatic** leaves (stomata only on upper surface)?
AHydrophyte (e.g. lotus — leaves float)
BXerophyte (e.g. Nerium — stomata on lower surface to reduce loss)
CMesophyte grass (stomata on both surfaces)
DAll angiosperms
Answer & Solution
Correct answer: A. Hydrophyte (e.g. lotus — leaves float)
Epistomatic: stomata on UPPER surface only — typical of floating-leaf hydrophytes like Nymphaea, lotus. Lower surface is in water. Hypostomatic (Nerium): stomata on LOWER side. Amphistomatic (grass): both.
