Gametogenesis Concise Medical Knowledge
Plants have a number of factors that have made them desirable for the analysis of gamete development; these include late germline specification, the non-lethality of mutations affecting gamete.

GAMETOGENESIS IN PLANTS THE evolutionary origin of the reproductivecells furnishes one of the most fundamentalproblems connectedwith genetics, for upon a clear understandingof the subject depends the satis- factory solution of many subsidiaryproblems relating to animal and plant breeding.

In plants, gametogenesis is the last step of gametophyte development. The gametes are differentiated, together with accessory cells, within the multicellular male and female gametophytes. In both cases, the establishment of distinct cell fates from genetically identical haploid cells is underlined by distinct chromatin organization.

Gametogenesis, the process of forming mature germ cells, is an integral part of both an individual's and a species' health and well-being. This chapter focuses on critical male and female genetic and epigenetic processes underlying normal gamete formation through their differentiation to fertilization.. Marshall, & Plant, 2009), and.
What is Gametogenesis?
To define gametogenesis is to define the science that makes fertilization possible. Female gametogenesis in humans as well as female gametogenesis in plants is a part of the sexual reproduction system that would need gamete transfer for fertilization to take place. As per the gametogenesis definition, it is an important process that takes place.

14.1 Gametogenesis The Science of Plants
In gametogenesis of flowering plants, epigenetics is dynamic between the companion cell and gametes. Cytosine DNA methylation occurs in CG, CHG, CHH contexts (H = A, C, or T) of genes and transposable elements, and undergoes dynamic changes during reproduction. Cytosine methylation in the CHH context increases significantly during embryogenesis.

Gametogenesis is a biological process by which haploid male and female gametes are formed. This occurs in both plants and animals. In higher plants, there are two stages that are involved- sporogenesis and gametogenesis. Sporogenesis is the formation of spores whereas gametogenesis is the formation of gametes. Suggested Videos

. The sporangium in the ovary (where the female gametophyte will be formed) is called the megasporangium. Diploid microspore mother cells in the microsporangium and diploid megaspore mother cells in the megasporangium divide by meiosis to form four haploid micro- or mega- spores. These spores initiate the gametophyte phase.
