AI Generated Solution

The correct Answer is:
**Step-by-Step Text Solution:** 1. **Understanding the Assertion**: The assertion states that many plants can reproduce both asexually and sexually. Asexual reproduction in plants does not involve the formation of gametes (like pollen and eggs). Common methods of asexual reproduction include vegetative propagation (like layering, cutting, and grafting) and apomixis (seed formation without fertilization). 2. **Explaining Asexual Reproduction**: - **Vegetative Propagation**: This includes methods like layering (where a branch is placed in soil to root and grow) and cutting (where a part of the plant is cut and planted to grow). - **Apomixis**: This is a form of asexual reproduction where seeds are formed without fertilization. 3. **Understanding the Reason**: The reason states that parthenogenesis, a form of asexual reproduction, is also found in plants. Parthenogenesis occurs when an egg develops into a new individual without fertilization. This phenomenon can be observed in certain plants like pineapple and banana. 4. **Linking Assertion and Reason**: Both the assertion and reason are true. The assertion highlights that many plants can reproduce in both ways, while the reason explains one mechanism (parthenogenesis) that allows for asexual reproduction in some plants. 5. **Conclusion**: Since both the assertion and reason are true, and the reason provides a correct explanation for the assertion, we conclude that the statement is valid. **Final Answer**: Both the assertion and reason are true, and the reason is the correct explanation of the assertion. ---
