gamete造句

• 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。
• In addition , it has been found that the number of attached spores on the surface of ionic hydrogels was affacted by the crosslinking density of gels , but the germination ratio of attached spores and growth of gametes have nothing to do with the crosslinking density of gels
  此外，离子型凝胶表面孢子的附着量受凝胶的交联度影响，而孢子的萌发率以及配子体的生长发育均与凝胶的交联度无关。
• Despite this progress , however , women who lack ovaries altogether and men whose testicles have failed to develop or have been removed must still use donor gametes if they wish to have a child , which means that the child will not carry any of their genes
  尽管这种技术已经取得了很大进展，但是对于那些没有卵巢的妇女和睾丸发育不良或已切去睾丸的男子来说，如果他们想要孩子的话，就必须接受捐献者的配子，这意味着这样的孩子将不会携带任何他们的基因。
• Fertilization is a highly programmed process by which two radically different cells , sperm and egg , unite to form a zygol it is mediated by complementary molecules present on the surface of the respective gametes . especially the proteins in the sperm acrom play an important role , but only a little can be extracted from sperm . now large amount of proteins can be obtained easily using biological technique
  受精是配子间相互作用最后融合成合子的过程，是由配子各自表面蛋白分子互补介导的，特别是存在于精子顶体的蛋白，但从精子中提取量少，用分子生物学手段大量克隆表达所需蛋白为受精机理的研究提供了方便。
