उत्तर
- An orchid growing as an epiphyte on a mango branch is an example of commensalism.
- Commensalism is a connection between members of two species in which one benefits while the other is unaffected, mainly, i.e., neither is benefited nor hurt.
- A commensal may get shelter (protection), transportation, or assistance instead of or in addition to food.
- Epiphytes are space parasites that use trees merely for attachment and produce their own nourishment through photosynthesis.
- Vanda, an epiphytic orchid, has unique aerial roots (hanging roots) that hang freely in the air and collect moisture using velamen, a specific absorptive tissue.
