Question

in cuscuta roots like haustoria penetrate in to the host plant tissue.hari said that all plants contain this type of structure.do u agree support ur answer​

Answer 1

EXPLANATION:

I do not agree with Hari that all plants contain haustoria like structures. Cucuta is a class of parasitic plants. They grow in the soil with normal plant roots. But as it grows, if it encounters a plant in its surrounding from which it can obtain food and water, then Cuscuta develops these specialized roots called haustoria which penetrates into the host plant. In that case, the original soil roots die off.

Hence, haustoria are specialized roots present only in parasitic plants.
