| It is an asexual reproductive structure. | It is formed as a result of sexual reproduction. |
उत्तर २
- Zoospores are the microscopic, flagellated (motile) special asexual reproductive structures found in certain members of the kingdom fungi and simple plants like algae, whereas a zygote is a diploid cell formed by the fusion of male and female gametes. The zygote is usually nonflagellated.
- The pores are the structures that give organisms new organs, whereas a zygote is formed after fertilization and develops into a mature organism.
