Can Ca++ Ions Act as a Chemotropic Factor in Oenothera FertilizationBook Edition: 1. Pollen is a fine to coarse powdery substance comprising pollen grains which are male microgametophytes of seed plants, which produce male gametes (sperm cells).
Pollen grains have a hard coat made of sporopollenin that protects the gametophytes during the process of their movement from the stamens to the pistil of flowering plants, or from the male cone to the female cone of coniferous plants. Double Fertilization.
After pollen is deposited on the stigma, it must germinate and grow through the style to reach the ovule. The microspores, or the pollen, contain two cells: the pollen tube cell and the generative cell. The pollen tube cell grows into a pollen tube through which the generative cell travels.
Jun 04, · Starting with a clear explanation of the structure and form of pollen, the authors go on to examine the remarkable events from pollination to fertilization, and the many unseen ways in which pollen impacts our lives.

This chapter discusses the physiology of fertilization and fertilization barriers in higher plants. In higher plants, such as angiosperms, fertilization is mediated by the controlled processes of the progamic phase that lies between pollination, the transfer of the male gametophyte from the anthers to the perceptive organs, and syngamy, the fusion of the gametes in the process of double Cited by: 6.
Oct 13, · Successful pollen germination and pollen tube elongation in the stylar transmitting tissues lead to fertilization, the final step of the story of the male gametophyte. How are the pollen tubes containing the sperm cells accurately guided to the embryo sac with the egg cell.
