microsporogenesis meaning in Hindi

Examples

1. Two basic types of microsporogenesis are recognised, simultaneous and successive.
2. All of the species except the genera placed in Nartheciaceae express simultaneous microsporogenesis.
3. The plants demonstrate simultaneous microsporogenesis, the microspores are tetrad, tetrahedral, or isobilateral.
4. While there may be a continuum with intermediate forms, the type of microsporogenesis has systematic significance.
5. Orchids have simultaneous microsporogenesis and inferior ovaries, two characters that are typical of the'lower Asparagales '.
6. In simultaneous microsporogenesis meiotic steps I and II are completed prior to cytokinesis, whereas in successive microsporogenesis cytokinesis follows.
7. In simultaneous microsporogenesis meiotic steps I and II are completed prior to cytokinesis, whereas in successive microsporogenesis cytokinesis follows.
8. In megasporogenesis, often three of the four spores degenerate after meiosis, whereas in microsporogenesis all four microspores survive.
9. Two differences between these two groups ( although with exceptions ) are : the mode of microsporogenesis and the position of the ovary.
10. Plants in Nartheciaceae show successive microsporogenesis which is one of the traits indicating that the family is sister to all the other members included in the order.
