The apical bud is the primary growing point located at the tip of the stem in plants. It is responsible for vertical growth and the production of new leaves and flowers.
5 Must Know Facts For Your Next Test
The apical bud contains meristematic cells that actively divide to facilitate plant growth.
Apical dominance is a phenomenon where the apical bud inhibits the growth of lateral buds, directing resources towards upward growth.
In some plants, removing the apical bud can encourage bushier growth by allowing lateral buds to develop.
The hormone auxin, produced by the apical bud, plays a crucial role in maintaining apical dominance.
Environmental factors such as light and gravity can influence the activity of the apical bud and its growth direction.
