| 1. | 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。 |
| 2. | Triticum aestivum ; megasporocyte ; meiosis ; cytoplasmic reorganization 小麦大孢子母细胞减数分裂细胞质改组 |
| 3. | Spore mother cell a cell that gives rise to four haploid spores by meiosis 孢子母细胞:可以发生减数分裂产生四个单倍体孢子的细胞。 |
| 4. | Aneuspory the production of an unusual number of spores during meiosis of a spore mother cell 异数孢子:在孢子母细胞减数分裂过程中产生不正常孢子数目的现象。 |
| 5. | Tapetum ( pl . tapeta ) a food - rich layer surrounding the spore mother cells in the anthers of vascular plants 绒毡层:维管植物花粉囊内包围孢子母细胞的富含营养物质的一层结构。 |
| 6. | 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。 |
| 7. | Within the rice anther , meiosis of the pollen mother cell produces microspores , which further develop into pollen grains 摘要水稻的小孢子母细胞在花粉囊中进行减数分裂产生小孢子,小孢子进一步发育成花粉粒。 |
| 8. | These abnormal mitochondria and vacuoles may be associated with the death of microspore mother cell which leads to the male sterility in cotton 线粒体和液泡结构异常可能是小孢子母细胞死亡造成雄性不育的细胞形态学特征。 |
| 9. | When microspore mother cell ( mmc ) preparing meiosis , calcium precipitates appeared in the cytoplasm of tapetal cells and callus wall surrounding mmc 当花粉母细胞进行减数分裂时,花药中的钙颗粒进一步增加,尤其是在小孢子母细胞的胼胝质壁中。 |
| 10. | These cells usually disintegrate , liberating food substances that are subsequently absorbed by the spore mother cells and the developing spores 这层细胞常常分解,释放出其内的营养物质,这些营养物质后来会被孢子母细胞和正在发育的孢子所吸收。 |
