What is the difference between terminal and lateral buds?
A terminal bud grows at the tip of a shoot and causes the shoot to grow longer. These buds produce hormones that move downward along the shoot, inhibiting the growth of other buds on that shoot. Lateral buds grow along the sides of a shoot and give rise to the sideways growth that makes a plant bushy.
