Macairea radula (Melastomataceae) has two stamen sets, poricidal anthers, pollen as the main floral resource and flowers visited by vibrating bees, a set of traits related to heteranthery. However, tristyly, which also predicts stamens differences within the same flower, has been proposed as...

– must be fertilized by pollen, which contains the male gametes, or sperm, of plants. A carpel of a plant includes three parts:stigma, style and ovary. A flower may have one or more carpels, and a pistil, by definition, consists of all of the carpels in a flower. ...
1. What are pollen sacs? What Pollen Sacs The pollen has a cytoplasm with a tube cell and an outer shell made of two layers. It contains the male reproductive cell or gamete, also known as the sperm cell, of the seed plant. It plays a role in the reproduction of flowering plants. ...
all stamens form the inner third whorl of a flower structure called theandroecium. Each stamen comprises a long tubular filament with a sac called theantherat the top.Pollengrains contain male reproductive cells or malegametesand are produced in anthers; each anther contains many pollen grains....
The male part of the flower is known as the stamen and usually surrounds the female pistil. Pollen Each pollen grain is filled with male gametophytes of the plant. A gametophyte contains the genetic code, DNA, of the plant in one-half the amount. Once a pollen grain reaches and fertilize...
