Answer:
Explanation:
Myosotis:
This plant produces the tiniest pollen grains. It has a diameter of about 0.006mm. As a blooming plant, it is capable of both sexual and asexual reproduction. The diameter of pollen grains varies during sexual reproduction in the myosotis plant.
Around 0.006mm is the correct option.
The size of pollen grain
Most pollen grains have a diameter of 10 to 70 m. There could be thousands of individual grains in just a small amount of pollen. The pollination agent frequently has a direct correlation with pollen size. Wind typically disperses the tiniest pollen grains, whereas larger pollen grains are frequently delivered by living things or by water.
The largest pollen grain plant
Plant Zostera:
The Zostera plant has the pollen grain with the longest length. On Zostera, the pollen grains can be up to 2500 m long. These grains' outer walls, which are longer and comprised of cellulose and sporopollenin, are tougher due to their length. Zostera is a kind of marine blooming plant that is also known as seagrass.
