Question

Epiphytic roots occur in?
A. Tinospora
B. Taeniophyllum
C. Orchids
D. Betel

Answer 1

Hint: Epiphytes are the plants where they associated to grow along with plants and usually it observed in the temperate zone (e.g., many mosses, liverworts, lichens, and algae) or in the tropics (e.g., many ferns, cacti, orchids, and bromeliads).

Complete Answer:
- Epiphytes are the plants where they combined to grow along with plants and normally it observed in the temperate zone (e.g., many mosses, liverworts, lichens, and algae) or in the tropics (e.g., many ferns, cacti, orchids, and bromeliads).
- As they are associated with plants, their roots are proportionally directed into air instead of underground.
- These roots hang in the air and hold velamen or spongy tissue for grasping moistness immediately from the environment.
- The epiphytic roots are lacking root hairs and root caps. As discussed, epiphytes are plant associates to grow along with other plants and their roots hang in air instead to grow in soil, they absorb the nutrients through their specialised tissue-based roots known as velamen. Epiphytes roots occur in the tropics of orchids, ferns, cacti and bromeliads.
- Epiphytic plants have been categorised into two types of roots such as the clinging roots; that helps the epiphytic plant to get fixed on the barks of the tree.
- The epiphytic roots: that hangs freely in the air and attracts dampness and stores it with the help of specialized tissue called velamen.

Hence the correct answer is Orchids.

Note: Epiphytes are the plants, which has the property of clubbing to grow, these plants can be seen in temperate zone or in the tropics and their roots will hang in the air & absorb special sponge like tissues such as cacti, fern, orchids.
