Examples
- The gametophyte is derived from the product of a reduction division in the megaspore mother cell .
该配子体是由大孢子母细胞进行减数分裂而来。 - Triticum aestivum ; megasporocyte ; meiosis ; cytoplasmic reorganization
小麦大孢子母细胞减数分裂细胞质改组 - In theterosporous species , a distinction is usually made between megaspore mother cells and microspore mother cells
在异型孢子体种类中，可区分为大孢子母细胞和小孢子母细胞。 - 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
例如在蒲公英中，在第一次减数分裂后，大孢子母细胞的染色体仍在一个细胞中，形成一个再组核。 - It was also found that the nuclear envelope disappeared earlier at the micropylar end than that at the chalazal end . the speed of the programmed cell death were different in three nonfunctional megaspores at the micropylar end and their relationships with the neighboring cells were also different . the biological significance was discussed about these phenomenon
还发现了大孢子母细胞合点端的核膜先于珠孔端的消失，并且珠孔端3个大孢子的死亡时间不同，与相邻细胞的关系也不同，进而讨论了这些现象的生物学意义。
