Question

A yellow sticky substance present on the surface of entomophilous pollen grains is

• A. Sporopollenin
• B. Lignosuberin
• C. Pollenkitt
• D. Mucopolysaccharide

Answer 1

The correct option is C Pollenkitt

Entomophilous plants are the plants which are pollinated by insects.

Pollenkitt is a covering of yellow sticky substance which is present around the pollen grain of insect pollinated pollen grains. Pollen kit is formed by tapetum. It is an oily layer that provides stickiness and specific odour to the pollen grains. Thus, it helps in insect pollination as the pollen get attached to the body of pollinators i.e. the insects.

So, the correct answer is C.
