AP BIOLOGY

Detailed explanation-1: -Such seeds float on air and are thus dispersed by wind.

Detailed explanation-2: -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-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.

Detailed explanation-4: -In the plant kingdom, water is natural and one of the fundamental sources of seed dispersal. In this mode of seed dispersal, seeds float away from their parent plant in rivers or ponds due to their light weight. Plants which grow near water bodies usually rely on water to transport their seeds to different places.

Detailed explanation-5: -Many marine, beach, pond, and swamp plants have waterborne seeds, which are buoyant by being enclosed in corky fruits or air-containing fruits or both; examples of these plants include water plantain, yellow flag, sea kale, sea rocket, sea beet, and all species of Rhizophoraceae, a family of mangrove plants.
