NEET BIOLOGY

Detailed explanation-1: -Because plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds. The most common methods are wind, water, animals, explosion and fire.

Detailed explanation-2: -Fur and Feathers Some seeds and fruits are adapted to stick to the fur or feathers (or clothing!) of unsuspecting animals; when the animal finally frees itself of its clingy passenger, the seed/fruit is usually far away from where it started.

Detailed explanation-3: -Examples include mangoes, guavas, breadfruit, carob, and several fig species. In South Africa, a desert melon (Cucumis humifructus) participates in a symbiotic relationship with aardvarks-the animals eat the fruit for its water content and bury their own dung, which contains the seeds, near their burrows.

Detailed explanation-4: -The hooked spines attach easily to the skin, fur, or even feathers of passing animals, which then transport the seeds whither the animals wander. When eventually the animals rub the burrs off their coats, the seeds separate and disperse to the soil.
