Question

why do roots grow under ground​

Answer 1

Answer:

Roots grow underground because for roots, gravity is more strong a tropic movement than others. So roots grow towards earth. Also, the major function of roots is to absorb water from underground subsoil, therefore roots are present below the soil.

Answer 2

Answer:

• It is essential for roots to grow down so they can explore the soil and maximise their water uptake. But how they know that is a question that has fascinated scientists since Darwin. Now scientists led by The University of Nottingham have found the answer.

• Gravity profoundly influences plant growth and development. But after years of academic research the interdisciplinary team from the UK, Germany, France, Belgium, Sweden and the US has finally identified how that process happens. Their results have been published in the leading academic journal Proceedings of the National Academy of Sciences of the United States of America (PNAS).

• With funding from the Biotechnology and Biological Sciences Research Council (BBSRC), Malcolm Bennett, a Professor in plant science at The University of Nottingham and Biology Director of the Centre for Plant Integrative Biology, used newly developed technology to pinpoint what happens when plant roots decide to grow down and not up. He said: “This research really demonstrates the value of an interdisciplinary approach to plant science questions. By combining the skills of mathematical modellers with experimental biologists we have a new range of tools with which to investigate root growth”.
