| 1. | The male gamete could not unite with the female . 雄配子不能与雌配子结合。 |
| 2. | In many organisms the male and female gametes are different . 很多生物体中雄配子与雌配子是不同的。 |
| 3. | The other male gamete fuses with the secondary nucleus, forming the primary endosperm nucleus . 另一个雄配子和次生核结合形成初生胚乳核。 |
| 4. | A study on the development of the anther and the male gametophyte in 单穗升麻的花药和雄配子体发育 |

| 9. | The endosperm is usually triploid and develops from the primary endosperm nucleus , the triploid nucleus resulting from the fusion of one of the male gametes from the pollen tube with the polar nuclei in the embryo sac 胚乳通常是三倍体,由初生胚乳核发育而来,三倍体核来源于花粉管中的雄配子与胚囊中两个极核的融合。 |
| 10. | The gametophyte ( pollen grain ) contains all the genetic information required to unite with the female gamete at fertilization and to form a new sporephyte . a relatively large number of genes are required to program pollen development 在高等植物中,花的发育是一个复杂的过程,涉及到由营养分生组织(或花序分生组织)向花分生组织的转变,花的形态建成以及雌、雄配子体的发育和分化。 |
