The microspore of a seed plant, haploid cells that comprise of give rise to the male gametophyte (microgametophyte)
The male gametophyte in higher plants.
Pollen grains are produced by flowering plants, gymnosperms and cycads as a way of reproducing even in areas where water is not easily available. As such, pollen represents an advanced feature of adapting to a life on land. Individual pollen grains are tiny, with almost no reserves inside them; essentially they are 'male' genetic material wrapped in two membranes. The outer membrane is smooth and rounded in wind-pollinated plants, and often highly sculpted and shaped in insect-pollinated plants. Pollen grains represent the vestiges of a highly reduced male gametophyte generation.
a marvelous structure evolved by plants to protect and deliver the male
a microscopic plant that carries the male genome, which is one-half the genetic complement of the parent plant
an immature male gametophyte
a partially developed male gametophyte, the sperm cell of the plant
a small object which holds the male cells of a plant
A small structure of higher plants that contains haploid male gamete nuclei and is surrounded by a double wall, the exine and intine. Pollen grains are transported from the male stamen to the female stigma in a process called pollination.
One of the granular microspores that occur in pollen and give rise to the male gametophyte of a seed plant.
