Definition of pollen in English:

pollen

noun ˈpɒlənˈpɑlən

mass noun

A fine powdery substance, typically yellow, consisting of microscopic grains discharged from the male part of a flower or from a male cone. Each grain contains a male gamete that can fertilize the female ovule, to which pollen is transported by the wind, insects, or other animals.
Example sentencesExamples
- Potential foods included not only pollinating insects of angiosperm flowers but also the pollens, nectars, fruits, seeds and foliage of angiosperms themselves.
- What, then, are the roles of the two different flower types in pollen production?
- This species has a peculiar mechanism by which the flower dispenses pollen to different visitors.
- It is a beautiful white lily flower with big buds of pollen in its centre.
- Freshly harvested pollen was dusted onto a microscope slide with a brush to which four or five drops of stain were added.
- This could help relieve pollen limitation caused by insufficient quantity of pollen.
- Most is caused by grass pollen, but tree pollen can also cause reactions.
- Pollen traps also indicate that pollen is shed directly into the air, permitting wind pollination.
- The production of pollen and seed cones was studied in five branches chosen at random on each individual.
- In addition to seeds, the promoters directed reporter gene expression in pollen and in seed coats.
- Pollinators visit flowers in search of oils, floral fragrances, pollen or floral nectar.
- Each experiment was carried out on flower heads which had been protected from foreign pollen by bagging.
- Plants produced smaller flowers producing less pollen and with poor germination and tube growth.
- The egg cell is fertilized by pollen from the male sex organs, the stamens.
- The stigmas were then pollinated with pollen from a flower whose anther had dehisced that day.
- I was intrigued with how they gathered pollen and nectar from flowers to make honey.
- These bees visited flowers in search of pollen, adopting a supine posture as they entered the corolla tube.
- Native social bees visit only male inflorescences in search of pollen and nectar.
- Bees occasionally collect olive pollen, but wind is the primary pollination vector.
- Females produced more pollen per anther than males, and pollen size was the same in both sexes.

Origin
