why do roots grow downwards

Answer 2

Hello friend !!!

Here's the answer you are looking for

The main purpose of roots is to absorb nutrients and water for the plant in order to perform different metabolic activities.

These minerals, nutrients and water is available in the soil in absorbable form for the plants. These are also available in air but in trace amount which is not sufficient and not in the absorbable form for the plants.

Hence they grow downwards towards the soil in order to get enriched nutrients, minerals and water.
