10827.	Question : The essential functions of roots are anchorage and absorption of water and minerals in the terrestrial plant. What functions are associated with the roots of aquatic plants ? How are roots of aquatic plants and terrestrial plants different?
Answer» Solution :Generally terrestrial root show network of branches that functions to absorb water and minerals from the soil and to FIX in the soil. While in aquatic PLANTS modifications of their normal function and deviations are seen e.g. In Trapa, Tinospora like plants root are GREEN and much branched that increases area for photosynthesis. While in plants like Jucia, they become like ballons because AIR comes outside of water. So plant can float on water and can do exchange of gases. Difference between Aquatic Root and Terrestrial Root

Discussion

10828.	Question : The essential functions of roots are anchorage and absorption of water and minerals in the terrestrial plant. What functions are associated with the roots of aquatic plants. How are roots of aquatic plants and terrestrial plants different?
Answer» Solution :(i) ROOT packets present at tips of roots in Pistia and Lemna perform the function of balancers. (ii) In Hydrilla and CERATOPHYLLUM roots perform the functions of balancers and anchorage. (III) In TRAPA, the roots turn green and become PHOTOSYNTHETIC. In terrestrial plants, roots mainly perform the functions of anchorage and absorption of minerals and water.

Discussion

10829.	Question : The essential functions of roots are anchorage and absorption of water and minerals in the terrestrial plant. What functions are associated with the roots of aquatic plants. How are roots of aquatic plants and terrestrial plants different ?
Answer» SOLUTION :Usually the terrestiral roots show a branched network that helps in anchorage and absorption of WATER and minerals from soil to the plant. While in aquatic plants, roots show MODIFICATIONS and deviation from their normal function. E.g., in plants LIKE Trape, Tinopora the roots are greeen and highly branched to increase the photosynthetic area, whereas in plants like Jussiaea, They get inflated due to air project out of water so to HELP the plant in floating and exchanged of gases.
