What is found at the end of each stem and in each leaf axil of actively growing broadleaf plants?

The correct answer is exposed growing points, which are vital to the growth and development of broadleaf plants. At the end of each stem, the growing point is known as the terminal bud, which is responsible for the plant’s vertical growth. This terminal bud is typically protected by overlapping scales and contains the meristematic tissue where new cells are generated, allowing for increasing height or length.

In each leaf axil, there are also growing points that can lead to the development of lateral shoots or branches. These axillary buds, which are located at the junction where the leaf stem meets the main stem, can also produce new growth, contributing to the overall structure of the plant.

Understanding the role of these exposed growing points is essential in pest management as they are the sites where growth is most active, and thus they can be affected by pests or diseases targeting those regions. Healthy growing points are crucial for maintaining the vigor and overall health of the plant.
