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.

What is a terminal bud used for?
The role of the terminal bud is fairly straightforward. It allows for the plant to grow taller, thereby allowing it to gain more resources in order to live. It is essential for the plant to grow and gain more height on surrounding plants. You can liken a terminal bud, in a way, to a human being.
What is the meaning of terminal buds?
A terminal bud occurs on the end of a stem and lateral buds are found on the side. A head of cabbage (see Brassica) is an exceptionally large terminal bud, while Brussels sprouts are large lateral buds.
What is apical bud and terminal bud?
The terminal bud is also known as the apical bud. It is the area which is the primary growth point at the tip of the stem that forms the dominant bud. The terminal bud will make the lateral buds dormant (apical predominance). Both buds are created by the apical meristem shoot movement.
What happens if a terminal bud is removed?
If a terminal bud is removed, the growth of lateral buds is stimulated and the plant becomes bushier. But if lateral buds or branches are removed, growth is channeled into the terminal bud and the plant becomes taller or longer.
Why is terminal bud considered an active part of the stem?
In stems, mitosis in the apical meristem of the shoot apex (also called the terminal bud) produces cells that enable the stem to grow longer and, periodically, cells that will give rise to leaves. The point on the stem where leaves develop is called a node.
What are terminal bud scars?
Rather, it refers to the bud at the end of the branch. As these terminal buds burst forth with new growth, the protective scale normally falls away, leaving a bud scar. Bud scars look like rings around stems and branches of trees and other woody plants. Bud scars are from the terminal bud on a stem.
What does Terminal mean in biology?
terminal. 1. Forming or pertaining to an end, placed at the end. 2. A termination, end or extremity.
How does the terminal bud differ from the axillary buds?
A node from which a flower will sprout from. What is the difference between an axillary bud and a terminal bud? Axillary buds are found at the nodes and can form branches, shoots or leaves. Terminal buds are differentiated apical meristems in a state of inactive growth.
What is terminal or axillary?
The terminal bud arises from the tip of the stem and axillary buds arise from the leaf node of the stem. Hence both the terminal and axillary buds arise from the apex (apical meristem).
Why do tea plants decapitate?
In higher plants, the growing apical bud inhibits the growth of the lateral buds. ... Decapitation usually results in the growth of lateral buds. It is widely applied in tea plantations & hedge-making. Because, tea plants and hedges should be maintained at lower height.
Why on removing the terminal bud the plant gets bushier?
But when a terminal bud is removed, plant growth is affected. The secondary buds that are lateral, come into action and cause the plant growth in lateral directions, due to which the plant becomes bushier.
Why do plants become bushier when the shoot terminal buds are cut?
Auxin is a plant hormone produced in the stem tip that promotes cell elongation. ... If the apex of the shoot is removed (by a browsing animal or a scientist), the auxin is no longer produced. This will cause the lateral buds to break their dormancy and begin to grow. In effect, the plant becomes bushier.
What is auxiliary bird?
An axillary bud is an embryonic or organogenic shoot which lies dormant at the junction of the stem and petiole of a plant. It arises exogenously from outer layer of cortex of the stem. ... If there is only one leaf, then the plant is considered single-leafed, if not it is considered multi-leafed.
How old is the twig?
The age of the whole twig can usually be determined by counting back from the longest branch. You can tell the age of side branches too, by counting the bud scale scars back from their tips. You can also tell how good the growing season was by the distance between bud scale scars.
How do you know how old a stem is?
To calculate the age of this young stem cross section, just count the number of thick purple rings (bands) outside of the yellow pith. Only count the layers of woody growth (xylem tissue), do not count the central core of pith.
How can you tell a woody stem?
Woody dicot stems are used in tree and shrub identification. Features to look at include the cross section shape of the pith (rounded, star, or triangular) and whether the pith is solid, hollow, or chambered.
