Question

9. Write the advantage of the following features: i. stilt roots ii. Pure stands iii. Succulent stems iv. Pneumatophore​

Answer 1

Answer:

(1) stilt roots:

the roots are the organs of a plant that are modified to provide anchorage for the plant and take in water and nutrients into the plant body, which allows plants to grow taller and faster.[1] They most often lie below the surface of the soil, but roots can also be aerial or aerating, that is, growing up above the ground or especially above water.

(2) pure stands:

They can provide an economical source of livestock feed, reduce labor requirements, build soil tilth and fertility, reduce erosion, and reduce invasions of noxious and poisonous weeds.
