Возможно, вы имели в виду: microsporogenesis and micro gametogenesis |
Ans. Microsporogenesis is the process by which pollen grains (microspores) are formed from sporogenous tissue. Microgametogenesis is the process by which male gametes are formed from the generative cell nucleus present inside the pollen grain via mitosis.
Microspores i.e., the pollen grains, are developed inside microsporangia. The microsporangia are developed inside the corners of the 4-lobed anther. |

Apart from microsporogenesis in staminate flowers, the development of anthers and early microsporogenesis were also observed in pistillate flowers. |
Within the anther, male meiosis produces microspores, which further develop into pollen grains, relying on both sporophytic and gametophytic gene functions. |
Microsporogenesis and microgametogenesis. The sporogenous tissue consists of cells with conspicuous nuclei and dense cytoplasm (Figure 4A). Then, mitotic ... |
The aim of this paper is to investigate the anther development, including the microsporogenesis and microgametogenesis in several species of Heliconia. |
The formation of pollen grains from the microspores is termed microgametogenesis. · It begins with the expansion of the microspore and the formation of a large ... |
Stamen is also known as microsporophyll. A typical stamens has three parts Anther: Anther is the upper fertile part which is the bilobed structure. |
