Bracts are modified leaves that grow near the base of a flower. They are often overlooked and thought to be part of the flower but are actually separate structures. Bracts can come in different shapes, sizes, and colors, depending on the plant species.
The main function of bracts is to protect the flower. They surround the flower and provide a layer of protection against pests, insects, and other environmental factors. In some cases, bracts are also used to attract pollinators. For example, the bracts of the poinsettia plant are bright red and serve as an attractant to pollinators.
One of the most well-known examples of bracts is the colorful leaves that surround the flower of the poinsettia plant. These leaves are often mistaken for flower petals, but they are actually modified leaves. The red or pink bracts of the poinsettia plant are also a common feature of Christmas decor.
Another example of bracts in action is in the case of the banana plant. The bracts of the banana plant are large and protect the developing fruit. They are also the reason why bananas grow in clusters.
Bracts are also found in some types of crops, such as rice and wheat. In these plants, bracts serve as a protective layer around the developing grain. The presence of bracts can also help improve crop yield by reducing grain loss.
In conclusion, bracts are leaf-like structures found near the base of flowers that serve protective and/or attractant functions for plants. They are often overlooked, but they play an important role in plant survival and reproduction. Understanding the function of bracts can help us appreciate the beauty and diversity of the plant world.
