Question

What type of transpiration is possible in the xerophyte Opuntia?

पर्याय

• Stomatal

• Lenticular

• Cuticular

• All the above

Answer 1

All the above

Explanation:

In xerophytes like Opuntia (a cactus adapted to arid environments), all three types of transpiration can occur:

1. Stomatal transpiration: through stomata (although reduced, they are present in the stem since leaves are modified into spines).
2. Cuticular transpiration: through the waxy cuticle covering the stem.
3. Lenticular transpiration: through lenticels in the stem.
