it is an asexual reproduction process D. it needs two types of gametes 相关知识点: 试题来源: 解析 C。解析:植物通过组织培养繁殖是无性繁殖过程。选项A,不是有性繁殖过程,A错误。选项B,组织培养繁殖是无性繁殖,但通常基因变异低,B错误。选项C正确。选项D,不需要两种配子,D错误。
The following are steps in a certain plant reproduction method: First, the pollen is transferred to the stigma. Then, the male and female cells combine. Which reproduction method is this? A. Asexual reproduction B. Vegetative propagation C. Sexual reproduction D. Clone reproduction ...
C。解析:Sexual reproduction involves the combination of genetic material from two different parents, so it is most likely to produce plants with different characteristics. Vegetative propagation, budding and fragmentation are forms of asexual reproduction where the offspring are genetically similar or ident...
