Pollen definition, the fertilizing element of flowering plants, consisting of fine, powdery, yellowish grains or spores, sometimes in masses. See more. Pollen is the microgametophyte in both gymnosperms and angiosperms. Recall that conifer pollen has four cells and inflated air sacs that serve as wings. In angiosperms, the pollen lacks wings and is reduced to only two cells: the generative cell and the tube cell. Below are two microgametophytes.

Pollen development is an important process in the plant life cycle and directly determines sexual reproduction. As well, pollen development relates to a series of events in cell division, cell.

(e) The ovule can be seen in this single megasporophyll. (f) Within this single ovule are the megaspore mother cell (MMC), micropyle, and a pollen. Pollen grains represents the male gametophytic generation. The pollen grains have a two-layered wall, the outer exine and inner intine. The exine is made up of sporopollenin and has germ pores. Pollen grains may have two-celled (a vegetative cell and generative cell) or three cells (a vegetative cell and two male gametes) at the time of shedding.

Very few works include the biochem istry or biology of pollen. The chapters in this book cover topics such as pollen grain counting using a cell counter; restricted pollination for tracing individual pollen tubes in a pistil; obtaining mutant pollen for phenotypic analysis and pollen tube dual-staining; analyzing intracellular gradients in pollen tubes; and measuring exocytosis rate in Arabidopsis pollen tube using corrected fluorescence recovery after.
Published August DOI: by: The book covers systematics, biogeography, life cycles, nesting behavior, enemies and associates, and flower associations, and is liberally referenced This book is recommended for institutional libraries, for hymenopterists, for those interested in pollination and plant-insect interaction, and for those who marvel at the organic diversity of this planet and worry for its s: 1.
This book is a reprint of the fourth edition, published inof the Textbook of Pollen Analysis and is unique in its approach as it discusses both the practical and theoretical aspects of palynology.
It uses palynological techniques as tools for solving problems in quaternary geology, ecology and archeology. LaFountain JR, Jr, LaFountain KL. Comparison of density of nuclear pores on vegetative and generative nuclei in pollen of Tradescantia.

The Developmental Biology of Pollen. In book: Plant Reproduction, Annual Plant Reviews, Volume 6., Publisher: Sheffield Academic Press, Editors: S.D. O'Neill and J.A. Roberts, pp Author: David Twell.
This volume explores a collection of experimental techniques used to investigate different aspects of pollen development and function, including its role in reaching the ovule and delivering the two sperm cells. The techniques discussed range from basic methodology to cultivate pollen in vitro to the sophisticated experiments involving micromanipulation, Lab-on-Chip technology, or high-end imaging.
Pollen germination in vitro is a reliable method to test the pollen viability. It also addresses many basic questions in sexual reproduction and particularly useful in wide hybridization.
Many pollen germination medium ranging from simple sugars to complex one having vitamins, growth regulators, etc. in addition to various minerals have been standardized to germinate pollen artificially.

Pollen: Development and Physiology focuses on pollen physiology, with emphasis on the living pollen grains, their growth, and essential biological functions. Topics covered in this book include the role of nucleus and cytoplasm in microsporogenesis; the development of the pollen grain wall; the metabolism of pollen tubes; pistil-pollen.
After maturation, pollen must interact specifically with the receptive female tissues and germinate a highly polarized pollen tube that rapidly grows through the style to the ovule.
Thus, pollen is an excellent model system for the study of meiotic events, cellular organization, cell-cell interactions and polar growth in plant biology.Pollination refers to the landing and subsequent germination of the pollen on the stigma.
Hence it involves an interaction between the gametophytic generation of the male (the pollen) and the sporophytic generation of the female (the stigmatic surface of the carpel).
Pollination can occur within a single flower (self-fertilization), or pollen can land on a different flower on the same or a.Hong Ma, Venkatesan Sundaresan, in Current Topics in Developmental Biology, Regulation of the asymmetric first pollen mitosis.
Following meiosis during early pollen development, the microspore nucleus first migrates to one side of the cell, with the formation of a large vacuole; then an asymmetric mitotic cell division produces a large vegetative cell and a small generative cell.
