D. The new plants are genetically identical to the parent plant. 相关知识点: 试题来源: 解析 D。解析:无性繁殖的特点是新植株与母株在基因上是完全相同的。选项A,无性繁殖不需要两株亲本植物,只需要一株,所以A错误。选项B,因为新植株与母株基因相同,所以不会有基因多样性,B错误。选项C,无性繁殖不涉及...
This liverwort can reproduce asexually via gemmae. Gemmae are small disks of green tissue that grow inside special cups. When mature they break off from the parent plant, often due to the action of raindrops. They scatter away from the parent plant and will eventually grow into new gametophy...
Many plants reproduce asexually as well as sexually. In asexual reproduction, part of the parent plant is used to generate a new plant. Grafting, layering, and micropropagation are some methods used for artificial asexual reproduction. The new plant is genetically identical to the parent plant fro...
The process of meiosis is characteristic of organisms that reproduce sexually. Such species have in the nucleus of each cell a diploid (double) set of chromosomes, consisting of two haploid sets (one inherited from each parent). These haploid sets are homologous—i.e., they contain the same ...
B。解析:When plants reproduce asexually through runners, new plants grow from underground stems that spread out from the parent plant. Option A is related to sexual reproduction as it involves seeds. Option C is about pollination which is part of sexual reproduction. Option D is also about sex...
解析 B。解析:草莓(Strawberry)可以通过匍匐茎(runners)进行无性繁殖,这种繁殖方式有助于它快速蔓延和适应环境。橡树(Oak tree)主要通过种子进行有性繁殖。向日葵(Sunflower)也是通过种子繁殖,属于有性繁殖。百合(Lily)通常通过鳞茎或种子繁殖,不是以发送匍匐茎这种无性繁殖方式为主,所以不选A、C、D。

To tackle these challenges, we developed a sexually and vegetatively reproducible inducer line of diploid seedless watermelon by disrupting the double fertilization process. This innovative approach has enabled the successful induction of diploid seedless watermelon across diverse varieties. This is a ...
A. it needs a lot of energy. B. it can produce many offspring quickly. C. it always results in weak offspring. D. it requires two different parents. 相关知识点: 试题来源: 解析 B。解析:通过出芽(budding)进行无性繁殖的好处是可以快速产生许多后代,这有助于植物在适宜的环境中快速繁衍和适应。
