Where are terminal buds located on a stem?

Terminal buds are located at the tips of the stems of plants. These buds are crucial for growth because they contain the meristematic tissue that enables the plant to extend upward and create new leaves and flowering shoots. The position at the tip allows the terminal bud to be the primary center of growth, which is essential for the elongation of the plant. This upward growth also plays a role in light capture for photosynthesis, as the plant stretches towards the sunlight.

In contrast, other locations mentioned do not reflect the typical position of terminal buds; for instance, buds at the base, middle of the stem, or under leaves generally refer to axillary or lateral buds, which are involved in producing branches or additional growth lower on the stem rather than the primary vertical growth.
