Detailed explanation-1: -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.

Detailed explanation-2: -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.

Detailed explanation-3: -The seeds of the orchid plant, dandelions, swan plants, cottonwood tree, hornbeam, ash, cattail, puya, willow herb, are all examples of plants whose seed are dispersed by the wind. In this method of seed dispersal, seeds float away from their parent plant.

Detailed explanation-4: -Water dispersal Many plants have seeds that use water as a means of dispersal. The seeds float away from the parent plant. Many aquatic plants and plants that live near water have seeds that can float, and are carried by water.
