NEET BIOLOGY

Detailed explanation-1: -They get stuck to the fur of animals and thus get spread to different places. Examples; Beggar tick, Xanthium, etc. Some seeds are swallowed by birds and animals along with fruits. These seeds get dispersed with bird or animal droppings.

Detailed explanation-2: -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-3: -Plants that depend on animals for dispersal have seeds that are adapted to traveling on the outside or the inside of the animal. Seeds with burrs or hooks can attach to an animal’s fur. For seeds that are transported internally, plants provide an attractive fruit pulp reward in return for the ride.

Detailed explanation-4: -Animals can disperse seeds by excreting or burying them; other fruits have structures, such as hooks, that attach themselves to animals’ fur. Humans also play a role as dispersers by moving fruit to new places and discarding the inedible portions containing the seeds.

Detailed explanation-5: -One of the significant ways that animals disperse plant seeds is by eating and pooing them out. Certain plant species, including many trees, enclose their seeds inside fleshy edible fruits that are appealing to hungry animals. These fruit-loving animals are called frugivores.
