14.1 Gametogenesis The Science of Plants
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

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.
14.1 Gametogenesis The Science of Plants
Gametogenesis is defined as the biological process in which the formation of gametes take place. The maturation of gametes take place in the reproductive cells of androecium and gynoecium. Male gamete formation: The formation of male gametes take place inside anther which consists of two steps: Microsporogenesis Micro gametogenesis

. 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.
Gametogenesis
Introduction Gametogenesis is the production of gametes from haploid precursor cells. In animals and higher plants, two morphologically distinct types of gametes are produced (male and female) via distinct differentiation programs. Animals produce a tissue that is dedicated to forming gametes, called the germ line.

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.

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.

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 development and the large size of their chromosomes.. Atxrcc3 results in aberrant male and female gametogenesis. These plants are also hypersensitive.

Gametogenesis is a biological process by which diploid or haploid precursor cells undergo cell division and differentiation to form mature haploid gametes. Depending on the biological life cycle of the organism, gametogenesis occurs by meiotic division of diploid gametocytes into various gametes, or by mitosis.
