Bumblebees collect pollen as a food source for themselves and their colony. Pollen is rich in proteins, vitamins and minerals, which is essential for the growth and development of bumblebees, especially for their larvae. When bumblebees collect pollen, it sticks to their hairy bodies. As they fly from flower to flower collecting nectar, they accidentally carry pollen from one flower to another, aiding in pollination and thus the reproductive process of plants. This makes bumblebees important pollinators and helps preserve ecosystems and improve agricultural yields.

Where is the pollen in a flower?

In a flower, the pollen is usually on the stamens, which are the flower's male reproductive organs. The stamens are located inside the flower head and are often long, thin and cylindrical in shape. At the tip of the stamens are the anthers, where the pollen is produced and preserved. The pollen may be visible on the outside of the anthers as fine grains or powdery substance.

However, some flowers have variations in their reproductive structures. For example, in flowers with no visible stamens, such as flowers of the lily-like family, the stamens are often inside the flower, where they are not immediately visible. In other cases, the stamens may have been modified into a different type of structure that protects the pollen, such as the male flowers of the corn plant, where the stamens meet in the plumes.

How long does pollen stay in a flower?

How long pollen stays in a flower depends on various factors, such as the type of flower, environmental conditions and the phase of flowering. In general, however, pollen in a flower does not last very long, as it is produced with the aim of being dispersed for pollination. Once a flower blossoms and has released its pollen, it can stay on the stamens for a few hours to a few days before drying up or being blown away by wind or insects. Some flowers produce pollen continuously throughout the flowering season, while others only produce pollen for a limited time before wilting.
