1. The sporogenous cell develops into microspore mother cell.

2. A sperm cell develops from a sperm mother cell.

3. At the stage of meiosis prophase, microspore mother cell begin to accumulate callose wall.

4. An unusual phenomenon that haustorial mother cell invaded intercellular hypha cell in wheat stripe rust was first reported.

5. When the tapetum disintegrates gradually later, microspore mother cell has still not entered meiosis, finally disintegrated.

6. So it defined as crassinucellate. The megaspore mother cell divides transversally to form a linear megaspore tetrad. The megaspore at the chalazal end develops into the embryo sac mother cell.

7. What does tumour of colloid mother cell have to treat plan?

8. Both hypha and haustorial mother cell were dikaryotic, while the typical mature haustorium was mono - karyotic.

9. The nucleus in shrinking cytoplasm of microspore mother cell enters into diakinesis stage .16.

10. Spore mother cell A cell that gives rise to four haploid spores by meiosis.

11. The nucleus in shrinking cytoplasm of microspore mother cell enters into telophase .17.

12. When microspore mother cell preparing meiosis, abundant calcium precipitates appeared in cytoplasm of tapetal cells and microspore mother cells, and in callus wall surrounding the cells.

13. Some abnormal division had been observed at microspore mother cell meiosis stage, e. g. chromosome pairing abnormally, aberrant dyad formation and asynchronous dyad division.

14. In dandelion ( Taraxacum ), for example, the chromosomes of the megaspore mother cell remain in one cell after the first meiotic division, forming a restitution nucleus.

15. The ovary contains 20-23 ovules. The ovules are hemitropous, with 2 integuments, tenuinucellate and the archesporial cell functions directly as the mega-spore mother cell.

16. Aneuspory The production of an unusual number of spores during meiosis of a spore mother cell.

17. A single archesporium differentiates immediately below the nucellar epidermis, it functions directly as the megaspore mother cell.sentencedict .com

18. The results showed that the microspore abortion occurred at the stage of microspore mother cell, tetrads and uninucleate microspore.

19. Potassium antimonate was used to locate calcium in the fertile and sterile anther of a thermo-sensitive genie male-sterile rice at microspore mother cell meiosis stage and at early microspore stage.

20. The gametophyte is derived from the product of a reduction division in the megaspore mother cell.

21. Megasporogenesis and Female Gametogenesis: Archesporium is of one cell, it directly functions as macrospore mother cell.

22. One inclusion was formed within the exosporium and remained with the spore after mother cell lysis.

23. A single archesporium differentiates immediately below the nucellar epidermis, it functions directly the megaspore mother cell.

24. The archesporial cell below nucellus epiderm functions directly as the megaspore mother cell.
