Velamen is found in
1 Roots of screwpine
2 Aerial and terrestrial roots of orchids
3 Leaves of Ficus elastica
4 Aerial roots of orchids
Explanation:
Exp:D Epiphyte is an organism that grows on the surface of the plant but does not derive nutrition or moisture from them. Majority of orchids are epiphytes. All epiphytic orchids and Vanda (a genus in the Orchid family) have a spongy tissue called velamen which is made up of multiple epidermis that covers the roots. Their roots are aerial and can perform photosynthesis by absorbing moisture and carbon dioxide from the air. Epiphytes are not parasites as epiphyte does not absorb nutrients from the host plant, unlike parasites.
