Ede4ka [16]

Explanation:

The plants which use animal or insects as pollination vector produce less pollen compared to the wind-pollinated plants.

This could be due to the reason that the chances of pollination by wind are less than the pollination by the animal or vectors.

The chances of pollination in animal pollination are high as the animals to feed on the useful product of plant will go to the other plants but in wind pollination, the chances are less as it depends on the speed and direction of the wind.

Thus, wind-pollinated plants produce high number of pollens.

Which is a common role of waxes in plants?
Zanzabum

Ans.

Plant waxes include complex compounds of alcohols, carbohydrates, acids, esters, hydrocarbons, and their combinations, present at the outside of epidermal cells. These waxes are strongly hydrophobic in nature and act as water repellents.

Thus, they provide protection to the aquatic plants against surface wetting. In land plants, waxes, present in cuticle prevent water loss, such as in dessert plants. Other functions of waxes include energy-storage, self-cleaning and reflection of UV radiation.
