What is a terminal bud?

A terminal bud is specifically defined as the bud located at the tip of a twig or shoot. This type of bud is crucial for the growth and elongation of the plant since it is responsible for producing new growth during the growing season. The terminal bud typically contains meristematic tissue, which allows for cell division and subsequent growth, making it vital for the development of stems and branches.

The terminal bud plays a significant role in determining the overall shape and height of a plant, as it is often the primary driver of upward growth. This contrasts with other types of buds, such as axillary buds, which are found in the leaf axils and can develop into branches or flowers but do not influence the tip growth directly. Understanding the function and location of terminal buds is essential for plant biology and horticulture, as these buds are key to a plant's morphology and developmental processes.
