The correct Answer is:
To determine which organisms exhibit parthenogenesis, we need to analyze the given options based on the definition and characteristics of parthenogenesis. ### Step-by-Step Solution: 1. **Understand Parthenogenesis**: - Parthenogenesis is a form of asexual reproduction where an egg develops into an organism without fertilization. This means that the offspring arise from the female gamete alone. 2. **Analyze Each Option**: - **a. Platyhelminthes**: These are flatworms that can reproduce both sexually and asexually, but parthenogenesis is not a common method of reproduction in this group. - **b. Rotifers**: Some species of rotifers reproduce via parthenogenesis, making this a valid option. - **c. Some annelids**: While some annelids can reproduce asexually, parthenogenesis is not widely recognized in this group. - **d. Honeybees**: In honeybees, unfertilized eggs develop into males (drones) through parthenogenesis, which is a clear example of this reproductive method. - **e. Some lizards**: Certain species of lizards can reproduce through parthenogenesis, making this a valid option as well. - **f. Cephalochordates**: These organisms primarily reproduce sexually, and parthenogenesis is not a characteristic of this group. - **g. Turkey birds**: Some turkey species can reproduce via parthenogenesis, making this another valid option. 3. **Conclusion**: - The organisms that exhibit parthenogenesis from the options provided are: - **b. Rotifers** - **d. Honeybees** - **e. Some lizards** - **g. Turkey birds** 4. **Final Answer**: - The correct options for organisms that exhibit parthenogenesis are **b, d, e, and g**.
