Question

Pollenkitt helps in the
A. Nutrition of pollen
B. Nutrition of insects
C. Formation of pollen
D. Sticking to the body of insects

Answer 1

Pollenkitt is the most common adhesive material found around the pollen grains of almost all animal pollinated angiosperms, while trifine appears to be limited only to Brassicaceae. The protoplasts of tapetal cells have different developmental patterns depending on the products formed during their development and degeneration

Complete answer: There is a sticky layer known as the pollen coat of pollen kit On the surface of the pollen, that is a rich source of proteins, lipids, vitamins, phenolic compounds, and minerals for the bees.

Additional information:
There are two types of sticky pollen shell material in angiosperms, both produced by the anther mat. If trifine is formed, the protoplasts of the tapetal cells lose their individuality at the microspore stage. If pollenkitt is formed, its content degenerates in later stages. The contents of the cells are completely reabsorbed when the mature pollen is not surrounded by any sizing material.

So the correct answer is Sticking to the body of insects.

Note: The multiple functions of pollenkitt, deduced from personal observations and from the literature, act in the period between the opening of the anther and the hydration of the pollen on the stigmatization; These are: (1) keep the pollen in the anther until it is dispersed; (2) to allow the second presentation of pollen; (3) to facilitate the dispersal of pollen; (4) to protect pollen from water loss; (5) to protect pollen from ultraviolet radiation; (6) to maintain the sporophytic proteins responsible for recognizing pollen stigma in exine cavities; (7) protect from the pollen protoplasts from fungi and bacteria.
