The structure and function of microfilaments (MFs) and microtubules (MTs) are described in the binucleate/bicellular pollen tubes of Nicotiana tabacum. In this species the pollen grain and tube are formed of two cells; the vegetative cell (VC) enclosing the generative cell (GC). After pollen...
What is Pollen Grain? What Does Pollen Contain? Function of a Pollen Cell Lesson Summary FAQs Activities What textures can pollen grains have? Pollen grains can have a variety of textures, including smooth, net-like, bumpy, and parallel striations. These textures can be used to help identif...

Pollen grains are produced by the male structure of the flower and pollen grains are produced in, specifically the anther of flower-bearing plants (angiosperms) or in the microsporangia of gymnosperms. The structure of pollen grain assists with their function. The function of the pollen grain ...
The pollen wall, an essential structure for pollen function, consists of two layers, an inner intine and an outer exine. The latter is further divided into sexine and nexine. Many genes involved in sexine development have been reported, in which the MYB transcription factor Male Sterile 188...
The development and function of the male gametophyte is amazingly well conserved across flowering plants. Following pollen grain hydration, a pollen tube starts to develop. The vegetative cell, hosting the generative cell or the two sperm cells, travels along extensible tip of the pollen tube, the...
