What does pollen mean

Pollen in plants is used for transferring haploid male genetic material from the anther of a single flower to the stigma of another in cross-pollination. In a case of self-pollination, this process takes place from the anther of a flower to the stigma of the same flower. Pollen is infrequently used as food and food supplement.

A pollen count is the measurement of the number of grains of pollen in a cubic meter of air. High pollen counts can sometimes lead to increased rates of allergic reaction for those with allergic disorders. Usually, the counts are announced for specific plants such as grass, ash, or olive. These are tailored to common plants in the measured areas.

What is the function of the pollen?

The ultimate function of pollen is to deliver male gametes (sperm) from the stamen of a plant to an ovule for fertilization of an egg, which then develops into a seed.

What is pollen in plants?

Introduction. Pollen is the substance that causes plants to form seeds. New plants then can grow from the seeds. Both flowering plants and conifers (plants that grow seeds inside cones) make pollen. A grain of pollen is so tiny that it is best viewed through a microscope.

What is pollen made from?

by HowStuffWorks.com Contributors. Next. Pollen is a fine powder made up of microspores produced by male plants. It is also called flower sperm. Pollen carries the male gametes (reproductive cells) of seed plants. Seed plants include both conifers (plants whose seeds grow inside cones) and flowering plants.

Introduction. Pollen is the substance that causes plants to form seeds. New plants then can grow from the seeds. Both flowering plants and conifers (plants that grow seeds inside cones) make pollen. A grain of pollen is so tiny that it is best viewed through a microscope.

What are seed plants?

Seed plants include both conifers (plants whose seeds grow inside cones) and flowering plants. Some species self-pollinate when the pollen moves from the male part of the plant (the stamen) to the female part of the plant (the pistil).
