उत्तर
All the above
Explanation:
In xerophytes like Opuntia (a cactus adapted to arid environments), all three types of transpiration can occur:
- Stomatal transpiration: through stomata (although reduced, they are present in the stem since leaves are modified into spines).
- Cuticular transpiration: through the waxy cuticle covering the stem.
- Lenticular transpiration: through lenticels in the stem.
