gamete造句
例句与造句
- Meiotic observation and male gametes development in cytoplasmic male sterile of pepper capsicum annuum l
椒细胞质雄性不育系减数分裂和雄配子发生过程 - At fertilization , when the haploid gametes fuse , the diploid number of chromosomes is restored
受精过程中，单倍体配子融合，恢复了二倍体的染色体数目。 - A gamete containing a diploid number of chromosomes , rather than the usual haploid number
2一个包含二倍体数目染色体而不是通常单倍体数目染色体的配子。 - Such a gamete may be produced by tetraploid tissues , or it may be the result of faulty meiosis
这样的配子可能是通过四倍体组织或者是错误的减数分裂产生的。 - Antherozoid ( spermatozoid ) the male gamete of algae , some gymnosperms , and the non - seed - bearing plants
游动精子：藻类，某些裸子植物和没有种子形成的植物中的雄性配子。 - It's difficult to find gamete in a sentence. 用gamete造句挺难的
- Two diploid gametes may fuse to give a tetraploid zygote , or gamete may develop directly by parthenogenesis
两个二倍体配子融合可能产生一个四倍体合子，这样的配子也可以通过孤雌生殖直接发育而来。 - Autopoly - ploids may arise from the fusion of diploid gametes that have resulted from the nondisjunction of chromosomes at meiosis
同源多倍体通常可能来自在减数分裂过程中染色体不分离导致的二倍体融合。 - Diplont a diploid organism that represents the vegetative stage in life cycles in which haploidy is restricted to the gametes
二倍体生物：代表生活史中植物体阶段的二倍体生物，其单倍体仅局限于配子体。 - It is a multicultural flask - shaped structure made up of a narrow neck and a swollen base ( venter ) that contains the female gamete
颈卵器状似长颈烧瓶，由一条细长的颈部和膨大的腹部（内含雌性配子）组成。 - Generally meiosis occurs before gamete formation , resulting in the gametes being haploid ( having half the normal number of chromosomes )
在配子形成前通常会发生减数分裂，产生单倍体的配子（染色体数为正常的一半） 。 - When the gametes are readily distinguished as male or female , other therms may be used such as antheridium , archiegonum , or oogonium
配子很快地分化为雌性或雄性以后，其他的细胞会形成如精子囊，颈卵器，卵囊等器官。 - The gametes fuse to form a zygote , which develops into the sporophyte , and the spores germinate and produce the gametophyte , so forming a cycle
配子融合产生合子，进而发育为孢子体，孢子萌发产生配子体，形成一个循环。 - Karyogamy the fusion of two nuclei that exist within a common cytoplasm , as occurs in the formation of the zygote from two gametes
核配：同一个细胞中两个核之间的融合现象称为核配，核配发生在两个配子结合成合子的过程中。 - The haploid plant produces gametes mitotically and is thus termed the gametophytes while the diploid plant produces spores meiotically and is called the sporophyte
单倍体植物有丝分裂产生配子体，二倍体减数分裂产生孢子体。 - External fertilization occurs when gametes are expelled into a watery substrate from the parental bodies before fusion ; it is typical of sporebearing plants
当配子在融合之前从亲本体中排出到有水介质时发生体外受精，这是孢子植物的特征。
