What are sucking roots? Give examples.

1 Answer


Sucking roots are also called as haustoria. These are small root which penetrates the host tissue. The haustoria of partial parasite penetrate and make contacts with host xylem tissue since they are in need of water and nutrients. Whereas the haustoria of total parasite makes contact with the phloem tissue, since they are in need of photosynthetic materials.
