Which of the following statements about asexual reproduction in plants is correct? A. It is not a common method for plant adaptation. B. It often involves the exchange of genetic material between different plants. C. It can help plants reproduce quickly in a favorable environment. D. It ...
A. Fragmentation B. Self - pollination C. Bulb division D. Stem layering 相关知识点: 试题来源: 解析 B。解析:自花授粉是有性繁殖方式,不是无性繁殖方式。选项A,分裂繁殖是无性繁殖方式,A错误。选项B正确。选项C,球茎分裂是无性繁殖方式,C错误。选项D,茎压条是无性繁殖方式,D错误。
C。解析:Grafting is a method of asexual reproduction in plants. It involves joining parts of two different plants together so that they grow as one. Fertilization is part of sexual reproduction. Seed dispersal is related to the spread of seeds after sexual reproduction. Cross - pollination is ...
It is a faster way to produce new plants D. It requires a lot of E. nergy 相关知识点: 试题来源: 解析 C。解析:植物无性繁殖的一个优势是能够更快速地产生新的植株。因为无性繁殖不需要经过复杂的配子结合等过程。选项A,产生多种多样的后代是有性繁殖的优势;选项B,无性繁殖产生的后代基因与亲本...
试题来源: 解析 B。本题考查植物无性繁殖的方式。A 选项“Pollination(授粉)”和 C 选项“Fertilization(受精)”以及 D 选项“Seed dispersal(种子传播)”都涉及两性生殖细胞的结合,属于有性生殖。B 选项“Budding(出芽)”是植物无性繁殖的一种方式。
Vegetative propagation is a form of asexual reproduction in plants. It is when a new plant emerges from vegetative parts, such as specialized stems, leaves, and roots. Then, they form their own root system and grow. This form of reproduction is used by horticulturists in propagating plants th...
Not all plants need to reproduce sexually. The bramble plant produces roots at the end of this long stem; from here a new plant will grow. In spite of this method, however, sexual reproduction is still a major factor in the reproductive cycle of the bramble plant. ...
In asexual reproduction of plants, which part can be used for reproduction? A. Only the root B. Only the flower C. Leaves, stems or roots D. Only the seed 相关知识点: 试题来源: 解析 C。解析:在植物的无性繁殖中,叶子、茎或者根都可以被用于繁殖。例如,有些植物可以通过扦插茎来繁殖,有些...
C。解析:Asexual reproduction in plants has the characteristics that offspring are genetically identical to the parent and it only requires one parent. Types such as vegetative propagation and budding are forms of asexual reproduction. However, the union of male and female gametes is a characteristic...
Natural methods of asexual reproduction include strategies that plants have developed to self-propagate. Many plants—like ginger, onion, gladioli, and dahlia—continue to grow from buds that are present on the surface of the stem. In some plants, such as the sweet potato, adventitious roots or...
