Describe plants that reproduce asexually 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 genet...
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。
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...
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...
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。
Most flowering plant species reproduce primarily by outcrossing, including the great majority of trees, shrubs, and perennial herbs. Adaptations that prevent self-fertilization include self-incompatibility (genetic recognition and blocking of self-pollen) and dioecy (separate male and female individuals)....
Plants have to complete the vegetative phase to reach a certain stage of growth and maturity. It is only after this period that they can reproduce sexually. The higher order plants, the reproductive phase of the plant is characterized by the flowering. This flowering phase in plants can vary ...
and Tropical Examples Vegetative reproduction is a form of asexual reproduction in plants. It does not involve flowers, pollination and seed production. Instead, a new plant grows from a vegetative part, usually a stem, of the parent plant. However, plants which reproduce asexually almost always...
Plants reproduce sexually through the fusion of male and female gametes in the flower. Asexual reproduction is through stems, roots and leaves.
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 ...
