define of root...............? ​

Answer 1

Explanation:

The plants that we see today is the result of billions of years of evolution. Today, plants cover almost 30 per cent of the total landmass and account for the 50 per cent of the plant’s productivity (generation of biomass). Plants fulfil many roles in the ecosystem. They are a source of food, nutrition, shelter, maintain the integrity of soil (by preventing erosion) and most importantly, they are the main source for balancing the oxygen level in the atmosphere.

Anatomically, plants are very complex organisms and are classified into various types based on certain defining characteristics. Roots are very important structures that provide a variety of functions, but contrary to popular belief, all plants do not have roots. Roots are absent in plants like mosses and liverworts.
