Burr (Botany)
Burrs are seed or fruit structures found in various plants, characterized by their spiky or prickly surfaces. These adaptations help burrs cling to fur, clothing, or other surfaces, aiding in seed dispersal. Common examples of plants that produce burrs include burdock and cocklebur.
Burrs can be a nuisance in outdoor activities, as they tend to attach easily to pets and clothing. However, they play a crucial role in the life cycle of plants by ensuring that seeds are spread over a wider area, promoting genetic diversity and colonization of new habitats.
