Question

defence of microsporogenesis and megasporogenesis

Answer 1

Microsporogenesis  And Megasporogenesis

Explanation:

1. Microsporogenesis. The arrangement of microspores inside the microsporangia (or dust sacs) of seed plants. A diploid cell in the microsporangium, called a microsporocyte or a dust mother cell, experiences meiosis and offers ascend to four haploid microspores.  
2. Megasporogenesis is the procedure of arrangement of megaspores in the angiosperms.
3. The megaspore mother cell (MMC) gets changed over into megaspores by the procedure of megasporogenesis. It experiences meiosis to deliver four megaspores. In most blooming plants, just a single megaspore is utilitarian while the other three savage.  
4. Microsporogenesis brings about the arrangement of haploid microspores from a diploid microspore mother cell. Then again, megasporogenesis brings about the development of haploid megaspores from a diploid megaspore mother cell.
5. Microsporogenesis - The arrangement of microspores inside the microsporangia of seed plants.
6. Megasporogenesis - The arrangement of megaspores inside the ovules of seed plants. A diploid cell in the ovule, called a megasporophyte or a megaspore mother cell, experiences meiosis and offers ascend to four haploid megaspores.  
7. Microsporogenesis is a significant procedure in plant generation, which incorporates a few arrangement of formative stages from sporogenous cells to microspores. Any capricious aggravation during the meiotic procedure lessens gamete practicality.  
8. Microsporogenesis-At the finish of microsporogenesis dust grain is shaped which have a generative cell/germ cell, a vegetative cell and an external layer of sporopollenin.
9. Megasporogenesis-At the finish of megasporogensis a polygonum embryosac is shaped which contains 8 core and 7 cell.

Answer 2

Answer:

Microsporogenesis:

The process of formation of microspore from diploid microspore mother cell through meiotic cell division inside the microsporangia for pollen sacs is called microsporogenesis ___________OR___________

It is a process in which each microspore mother cell divides meiotically to form tetrad of haploid microspores (pollen grains).
