One example of a seed that contains burrs is the burdock seed. Burdock plants produce burrs that easily attach to fur or clothing, helping in seed dispersal.
Burrs help plants disperse their seeds by attaching to the fur or feathers of animals, enabling the seeds to travel to new locations for germination. This dispersal method increases the plant's chances of survival and colonization in diverse habitats. Additionally, the spiky structure of burrs may deter herbivores from feeding on the plant's reproductive structures.

Before fertilization, the seed is the ovule and the fruit is the ovary. The ovule contains the female gametophyte and will develop into the seed after fertilization. The ovary contains the ovule and will develop into the fruit after fertilization.
The structure that becomes fertilized in the ovary and contains the seed is called the ovule. After fertilization, the ovule develops into a seed, while the surrounding ovary tissue typically matures into the fruit. The ovule contains the female gamete, which, when fertilized by the male gamete, forms the zygote that ultimately develops into the seed.
A part of a seed which is inside the seed coat is called cotyledon and it contains EMBRYO and the stored food
Seed pods that get caught in animal fur and on human clothing are often from plants like burdock, which produces burrs. These burrs have tiny hooks that easily cling to fur and fabric, aiding in seed dispersal as they travel with animals or humans. This mechanism is an example of a natural adaptation for spreading seeds over distances.
Prickly burrs are typically made up of small hooks or barbs that allow them to easily attach to animal fur or clothing. These structures help the burrs to cling onto passing animals for seed dispersal.

Burrs in wool refer to the prickly seed pods from certain plants, such as burdock or thistles, that can cling to sheep's fleece. These burrs can be a nuisance during shearing, as they can damage the wool and make it more difficult to process. Additionally, they can irritate the sheep's skin, leading to discomfort. Removing burrs is important for maintaining the quality of the wool and the health of the sheep.

Burrs are caused by the seed dispersal mechanism of certain plants, particularly those in the Asteraceae family, which produce seed pods with hooked or spiky structures. These hooks cling to fur, clothing, or feathers, allowing the seeds to be transported away from the parent plant. This adaptation helps in spreading the species and increasing its chances of germination in new locations. Environmental factors and genetic traits also influence the formation of burrs in various plant species.
The seeds (burrs) of the Burdock are covered in hooks which catch onto the clothes of humans, or the fur of animals that brush against the ripe burrs. Eventually, the seeds, clustered in the burrs, shake loose and are spread over a wide area. Incidentally, it was this hook and cloth process that led to the Velcro fastening system, much used today.
