Question

Pollen kit is generally found in ___________.
(a)Anemophilous plant
(b)Entomophilous plant
(c)Ornithophilous plant
(d)Malacophilous plant

Answer 1

Hint: In the pollen grains of an insect-pollinated plant, a yellowish, viscous, sticky, and oily layer known as pollen kit. The pollen kit covers the exine and is made up of lipids and carotenoids. Pollen kit is secreted by tapetum (a specialized layer of nutritive cells).

Complete answer:
Pollen kit is generally found in the entomophilous plant. The plants in which pollination is done by insects are called entomophilous plants. Some insects are pollinators, particularly bees, Lepidoptera (butterflies and moths), wasps, flies, ants, and beetles.

Additional Information: -A pollen kit is the most common adhesive material present around the pollen grains of almost all angiosperms pollinated by animals.
-The following are the function of a pollen kit:
-To hold the pollen in the anther until dispersal
-To facilitate pollen grain dispersal.
-To protect the pollen grain from water loss and ultraviolet radiation.
-To maintain the sporophytic proteins responsible for pollen–stigma recognition inside exine cavities.
-To protect pollen protoplasts from fungi and bacteria.
-To keep together the pollen grains during transport.
-To make pollen attractive to insects and animals.
-There are types of sticky pollen coat and sticky material that exist in angiosperms, both produced by the anther tapetum.
-The majority of entomophilous flowers (75-80%) are pollinated by bees.
-Anemophily or wind pollination is a form of pollination whereby pollen is distributed by the help of wind. Almost all the gymnosperms are anemophilous.
So, the correct answer is, ‘Entomophilous plant.’

Note: The entomophilous flowers are usually brightly colored and scented and often secrete nectar. This adaptation occurs to attract insects for pollination. Some examples of entomophilous flowers are orchids and antirrhinums.
