NEET BIOLOGY

Detailed explanation-1: -Seeds are dispersed in several different ways. In some plants seeds are housed within a fruit (such as apples or oranges). These fruits, including the seeds, are eaten by animals who then disperse the seeds when they defecate. Some fruits can be carried by water, such as a floating coconut.

Detailed explanation-2: -Dates, rambutan, sea grapes, sea holly, tamarind, raspberry, sunflower, tomatoes are a few examples of plants whose seeds are dispersed by animals and birds.

Detailed explanation-3: -’Animals gulp down the fruits without chewing the seeds, digest the fleshy pulp and defecate the seeds. ‘ This ingestion process of dispersal is known as endozoochory.

Detailed explanation-4: -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-5: -The seed of these plants gets attached on the fur of animals with the help of these hooks and are carried away to different places, far from their parent plants. Examples of plants having seeds dispersed by animals are Dates, rambutan, sea grapes, sea holly, tamarind, raspberry, sunflower, tomatoes.
