Question

Write the difference between parasitic and epiphytic plants

Answer 1

Parasitic plants depend on the host plant for nutrients. They procure food, water or both from the host through specialised roots called haustaria. An example is the plant with largest flower-Rafflesia
Where as epiphytic plants suvh as orchids are independent on nutrient requirements. They just only depend on space. They have velamen roots which can absorb water from the air.
