Question

Seeds and fruits dispersed by wind have -
A. Wings
B. Juicy flesh
C. Hooks
D. Bigger size

Answer 1

Hint: Plants make seeds that can develop into new plants, however on the off chance that the seeds simply tumble to the ground under the parent plant, they probably won't get enough sun, water or supplements from the dirt. Since plants can't stroll around and take their seeds to different spots, they have created different strategies to scatter (move) their seeds. The most well-known strategies are wind, water, creatures, blast and fire.

Complete answer:
Have you ever blown on a dandelion head and watched the seeds drift away? This is wind dispersal. Seeds from plants like dandelions, swan plants and cottonwood trees are light and have padded fibers and can be conveyed significant distances by the breeze. A few plants, similar to kauri and maple trees, have 'winged' seeds. They don't drift away however they vacillate to the ground. With wind dispersal, the seeds are basically blown about and land in a wide range of spots. To help their odds that probably a portion of the seeds land in a spot reasonable for development, these plants need to deliver loads of seeds.
Seed dispersal is the development, spread or transport of seeds from the parent plant. Plants have restricted portability and depend upon an assortment of dispersal vectors to ship their propagules, including both abiotic vectors, for example, the breeze and living (biotic) vectors like feathered creatures. Seeds can be scattered away from the parent plant separately or all things considered, just as scattered in both existence. The examples of seed dispersal are resolved in large part by the dispersal system and this has significant ramifications for the segment and hereditary structure of plant populaces, just as movement examples and species associations. There are five principal methods of seed dispersal: gravity, wind, ballistic, water, and by creatures. A few plants are serotinous and just scatter their seeds because of an ecological boost. Dispersal includes the giving up or separation of a diaspore from the primary parent plant.
Some wind-scattered seeds, for example, those of the dandelion, can change their morphology to increment or lessen the pace of germination.There are likewise solid developmental requirements on this dispersal instrument.

Hence, the correct answer is (A).

Note:
Dependence on wind dispersal is normal among numerous weedy or ruderal species. Strange components of wind dispersal incorporate tumbleweeds, where the whole plant (aside from the roots) is passed up the breeze. Physalis natural products, when not completely ready, may now and again be scattered by wind because of the space between the foods grown from the ground covering calyx which goes about as an air bladder.
