Draw a Labelled Diagram of the Pollen Grain

Q. Draw a labelled diagram of the pollen grain

Pollen, a mass of microspores in a seed plant showing up as a rule as a fine residue. Every dust grain is a brief body of shifting shape and design, framed in the male designs of seed-bearing plants and moved by different means (wind, water, bugs, and so forth) to the female designs, where preparation happens.

By definition in science, dust or pollen grain is an assortment of microspores that helps with plant preparation and process. One more name for dust grain is microspore. Dust grains are tracked down in blooming plants in the male designs. 

Vacuole: Modalities of vacuolation happen in dust in similar ways as in different tissues. Generally speaking, autophagic vacuoles debase organelles, as in the microspore after meiosis, and can be viewed as cytoplasm tidy up following the change from the diploid sporophytic to the haploid gametophyte state.

Exine: Exine is the peripheral layer of the dust grain composed of sporopollenin. Sporopollenin is a profoundly safe polymer composed of phenolics, carotenoids, phenylpropanoids and unsaturated fats.

Tube cell: It is one of the two cells created by the division of the microspore core to improve the male gametophyte in higher plants and the capacities being developed of the dust tube.

Inline: Intine is the inward, less hard and softer layer of the pollen grain composed of gelatin and cellulose.

Generative cell: The generative cell is framed at the primary division of the microspore and partitions in the pollen grain or tube to shape two sperm cells. 

Germ pore: Microbe or Germ pore is the district of the exine layer of the dust grain, where the sporopollenin is missing.
