Adaptive Modifications in Plants · NCERT Biology

The primary function of haustorial roots in parasitic plants is to:

  1. Store carbohydrates for the host plant cells
  2. Absorb water and nutrients from the host
  3. Provide mechanical anchorage to the soil
  4. Carry out photosynthesis in shade habitats
Show answer and explanation

Correct answer: Absorb water and nutrients from the host

Haustorial roots penetrate host tissues to absorb water and nutrients. This adaptation allows parasitic plants to survive.
