The correct Answer is:
To solve the question regarding the statements about unisexual flowers, let's analyze each statement step by step. ### Step 1: Analyze Statement 1 - **Statement 1**: "Unisexual flowers are either staminate flowers or pistillate flowers." - **Explanation**: Unisexual flowers are indeed classified into two types: staminate (male) flowers, which produce stamens, and pistillate (female) flowers, which produce pistils. This means that unisexual flowers contain only one type of reproductive organ (either male or female) and not both. - **Conclusion**: Statement 1 is **correct**. ### Step 2: Analyze Statement 2 - **Statement 2**: "Both monoecious and dioecious plants have unisexual flowers." - **Explanation**: - **Monoecious plants** are those that have both male and female flowers on the same individual plant. This means they do not have unisexual flowers because they possess both types of flowers. - **Dioecious plants**, on the other hand, have male and female flowers on separate individual plants. This means that dioecious plants can have unisexual flowers, as each individual plant will only have either male or female flowers. - **Conclusion**: Since monoecious plants do not have unisexual flowers, Statement 2 is **incorrect**. ### Final Conclusion - **Correct Option**: Statement 1 is correct, and Statement 2 is incorrect. ### Summary of the Solution - Statement 1 is correct: Unisexual flowers are either staminate or pistillate. - Statement 2 is incorrect: Monoecious plants do not have unisexual flowers.
