Question

Suggest why plants die very quickly if their roots are cut off

Answer 1

Because it is from the roots that they absorb minerals and water. if the roots are cut off then the plants won't be able to get any minerals or water hence they will start using the stored food and water. when the stored supplies will be over they will have no way to live hence they will die. on the other hand, plants which have roots intact will get a constant supply of minerals and water hence will live longer.

Hope this answer helps.

Answer 2

It is so because the roots absorb water and minerals and hold the plant if the roots are cut then the roots cannot absorb water purely and cannot send the minerals to the parts of plants Secondly there can be a chance of washing away of plant by rain or by wind
