Microspores are land plant spores that…
Microspores are land plant spores that develop into male gametophytes, whereas megaspores develop into female gametophytes. The male gametophyte gives rise to sperm cells, which are used for fertilization of an egg cell to form a zygote. -

Each pollen mother cell (PMC) in the anther produces 4 microspore or pollen grains. Thus, anther with microspore or isolated pollen grains can be cultured on artificial medium to raise haploid plant. -
Microspores, or immature pollen grains, are…
Microspores, or immature pollen grains, are haploid cells that have the ability to regenerate into whole plants when exposed to appropriate culture conditions and stimuli. Cellular totipotency of microspores has been routinely exploited in the generation of doubled haploid populations for crop research and breeding16.25 abr 2018

Microspore – Wikipedia
- Summary: Microspore Microscopic photo of spores (in red) of Selaginella. The large three spores at the top are megaspores whereas the numerous smaller red spores at the bottom are microspores. Microspores are land plant spores that develop into male gametophytes, whereas megaspores develop into female gametophytes.[1] The male gametophyte gives rise to sperm cells, which are used for fertilization of an egg cell to form a zygote. Megaspores are structures that are part of the alternation of generations in many…

- Summary: Microsporocytes – an overview | ScienceDirect TopicsPlant EmbryologyMichael G. Simpson, in Plant Systematics (Third Edition), 2019POLLEN DEVELOPMENTDevelopment of microspores from microsporocytes is termed microsporogenesis. There are two basic types of microsporogenesis as determined by the timing of cytokinesis, which is the formation of a plasma membrane and cell wall that divides one cell into two (Figure 11.6A). If cytokinesis occurs after meiosis I, then microsporogenesis is…

- Summary: Sexual Reproduction in Angiosperms | Biology for Majors II Learning Outcomes Identify the structures involved in reproduction of angiosperms Male Gametophyte: The Pollen Grain The male gametophyte develops and reaches maturity in an immature anther. In a plant’s male reproductive organs, development of pollen takes place in a structure known as the microsporangium (Figure 1). The microsporangia, which are usually bilobed, are pollen sacs in which the microspores develop into pollen grains. These are found in…

- Summary: Microgametophyte Development in Cannabis sativa L. and First Androgenesis Induction Through Microspore Embryogenesis Introduction Cannabis sativa L. is a multipurpose crop used by humans since at least 10,000 years ago (Abel, 1980). It is an allogamous and anemophilous species, which includes short and neutral-day varieties with androecious, gynoecious and monoecious specimens. Nowadays, this species is gaining increasing attention due to its medical applications (Abrams, 2018; Urits et al., 2019). Biologically active terpenophenolic metabolites known…
