Which of the following seed scatter by sticking on the fur of the animal?

A. Mango

B. Coconut

C. Cotton

D. Xanthium

Seeds can be dispersed by wind, water, gravity, or animals.

• Coconut seeds are carried away by water.
• Cotton seeds are scattered by wind.
• Mango seeds are dispersed by animals, birds, or humans, as they eat the fruit and drop the seed elsewhere.

In this case, the correct example of seed dispersal is Xanthium.

About Xanthium

Xanthium, commonly known as cocklebur, is a genus of flowering plants belonging to the Asteraceae (daisy) family. It is widely distributed in America, eastern Asia, and parts of South Asia. These plants typically grow 51–119 cm tall with leaves arranged spirally.

Seed Characteristics & Dispersal

• Xanthium seeds develop inside a hard, spiny, double-chambered bur that contains a single seed.
• Each bur is about 0.8–2.0 cm long.
• The bur is covered with hooked spines that easily cling to the fur of animals or clothing of humans.
• Because the seeds stick firmly, animals unintentionally carry them far from the parent plant.

When conditions are favorable, these seeds germinate into new plants. Otherwise, they remain in a dormant stage until growth becomes possible.

Hence, Option (D) is the correct answer.
