AP BIOLOGY

Detailed explanation-1: -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-2: -The common dandelion is perhaps the most iconic, and well-known species to use wind dispersal. The windsail-like structure, called the pappus, opens and closes in response to moisture. On dry, windy days the pappus opens, catches the wind, and transports lightweight dandelion seeds far away from the parent plant.

Detailed explanation-3: -Seed Dispersal by Wind 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.

Detailed explanation-4: -Wind dispersal (anemochory) is one of the more primitive means of dispersal. Wind dispersal can take on one of two primary forms: seeds or fruits can float on the breeze or, alternatively, they can flutter to the ground.

Detailed explanation-5: -Cotton seeds are light and are covered with hair.
