The correct Answer is:
To solve the question, we need to evaluate each statement regarding the morphology of flowering plants and determine which ones are correct. ### Step-by-Step Solution: 1. **Understanding Flower Structure**: - Flowers are the reproductive structures of angiosperms (flowering plants). - They consist of four main whorls: - **Calyx** (outermost, made of sepals) - **Corolla** (next, made of petals) - **Androsium** (male reproductive part, made of stamens) - **Gynosium** (innermost, female reproductive part, made of carpels) 2. **Evaluating Statement A**: - **Statement A**: "In a unisexual flower, there is only one type of sporophyll." - **Evaluation**: This is correct. A unisexual flower has either only male (stamens) or only female (carpels) reproductive structures, thus having only one type of sporophyll. 3. **Evaluating Statement B**: - **Statement B**: "A complete flower will be either bisexual or unisexual." - **Evaluation**: This is incorrect. A complete flower (or perfect flower) must have both male and female reproductive structures (both stamens and carpels), making it bisexual. 4. **Evaluating Statement C**: - **Statement C**: "In the case of dicots, in a typical flower, we will see that it has one type of accessory leaves and two types of sporophyll." - **Evaluation**: This is also incorrect. A typical dicot flower has two types of accessory leaves (sepals and petals) and two types of sporophyll (stamens and carpels). 5. **Evaluating Statement D**: - **Statement D**: "Bisexual flowers have heterochromidias perianth." - **Evaluation**: This statement is incorrect. Heterochromidius refers to flowers that have distinct calyx and corolla, while perianth refers to a structure where sepals and petals are not differentiated. Therefore, these terms cannot be used interchangeably. ### Conclusion: - The only correct statement is **Statement A**: "In a unisexual flower, there is only one type of sporophyll."
