Answer 1

Answer:

Banyan tree has prop roots that mature into thick and woody trunk. ... This become indistinguishable from primary trunk with old age.

Explanation:

A banyan, also spelled "banian",[1] is a fig that begins its life as an epiphyte,[2] i.e. a plant that grows on another plant, when its seed germinates in a crack or crevice of a host tree or edifice. "Banyan" often specifically denominates Ficus benghalensis (the "Indian banyan"), which is the national tree of India,[3] though the name has also been generalized to denominate all figs that share a common life cycle and used systematically in taxonomy to denominate the subgenus Urostigma.
