EVERYDAY SCIENCE

Detailed explanation-1: -When the seeds are ready, the seed pods become dry. This causes the pod to split up and throw the seeds out of the pod with a force. This mechanism is called explosion method of seed dispersal.

Detailed explanation-2: -Seed Dispersal by Explosions Okra, Lupins, gorse, and broom are a few examples of plants whose seeds are dispersed by Explosions. Pea and bean plants also have pods and the seeds burst out when they ripen and pod has dried.

Detailed explanation-3: -There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus. These modes are typically inferred based on adaptations, such as wings or fleshy fruit.

Detailed explanation-4: -The most common methods are wind, water, animals, explosion and fire. Dandelion seeds float away in the wind. To make sure at least some of the seeds land in a suitable growing place, the plant has to produce lots of seeds.

Detailed explanation-5: -Seed dispersal can be accomplished through both abiotic and biotic mechanisms. Abiotic dispersal involves wind and water; biotic dispersal involves autogenic mechanisms, such as explosive fruits, and various animal agents, including insects, fish, reptiles, birds, and mammals.
