NEET BIOLOGY

Detailed explanation-1: -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-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. Dandelion seeds float away in the wind.

Detailed explanation-3: -Wind Dispersal Wind can carry seeds a long distance away from the parent plant depending on the size or weight of the seed. Plants like dandelions, milkweed, and cottonwood trees take advantage of tufts of hairs attached to their seeds called pappi.

Detailed explanation-4: -Dispersal by Wind: Seeds of some plants are light-weight and some hair-like or wing-like structures are present on them. Such seeds float on air and are thus dispersed by wind. Example: Dandelion, maple, drumstick, etc.

Detailed explanation-5: -Wind: Because some light-weight seeds float in the air, they are disseminated by the wind. Some seeds have long, feathery tails that help them fly, similar to a kite’s tail. Maple is an example.
