Question

why the side shoots of plant increase in length when turminal buds are removed

Answer 1

Auxin is secreted from apical region of plant-like shoot tip.

If the terminal bud is removed, the concentration of auxin falls. This allows cell division and elongation to take place inside shoot, thus increasing their length.

Hope this helps you....:)

Answer 2

Answer:

The tip of the stem produces a hormone known as auxin, which promotes cellular elongation and thereby the plant grows in length. However, if the terminal bud is removed, auxins are no more produced.

This leads to the lateral buds becoming active and beginning to grow. Hence, the side shoots of the plants increases and it becomes bushier.
