Sunflower and Rose are bisexual flowers because they contain both androecium (carpels) and gynoecium (stamens).
In epigynous flowers, the margin of thalamus grows upward enclosing the ovary completely and getting fused with it, the other parts of flower arise above the ovary. The ovary is said to be inferior e.g., guava, cucumber.

Directions : In the following question, the Assertions (A) and Reason...
Assertion: Sunflower and Rose are bisexual flowers.
Reason: Flowers in which the thalamus grows around the ovary fusing with its wall are called epigynous flowers.
The answer to this question is option B: Both A and R are true, but R is not the correct explanation of A.
Explanation:
1. Bisexual Flowers:
- A bisexual flower is a type of flower that contains both male and female reproductive structures, namely stamens and pistils, in the same flower.
- Sunflower and Rose both possess both stamens and pistils within their flowers, making them bisexual flowers.
- Hence, Assertion A is true.
2. Epigynous Flowers:
- Epigynous flowers are a type of flower where the thalamus, which is the receptacle of the flower, grows around the ovary and fuses with its wall.
- In epigynous flowers, the ovary is situated below the attachment point of other floral parts.
- This structure is characteristic of many plants, including sunflowers and roses.
- However, it is important to note that being epigynous does not necessarily make a flower bisexual.
- Epigyny refers to the position of the ovary in relation to other floral parts, whereas bisexuality refers to the presence of both male and female reproductive structures within the flower.
- Hence, Reason R is true, but it does not provide a correct explanation for Assertion A.
Conclusion:
- Both the Assertion and the Reason are true, but the Reason does not correctly explain the Assertion.
- Therefore, the correct answer is option B: Both A and R are true, but R is not the correct explanation of A.
Reason: Flowers in which the thalamus grows around the ovary fusing with its wall are called epigynous flowers.
The answer to this question is option B: Both A and R are true, but R is not the correct explanation of A.
Explanation:
1. Bisexual Flowers:
- A bisexual flower is a type of flower that contains both male and female reproductive structures, namely stamens and pistils, in the same flower.
- Sunflower and Rose both possess both stamens and pistils within their flowers, making them bisexual flowers.
- Hence, Assertion A is true.
2. Epigynous Flowers:
- Epigynous flowers are a type of flower where the thalamus, which is the receptacle of the flower, grows around the ovary and fuses with its wall.
- In epigynous flowers, the ovary is situated below the attachment point of other floral parts.
- This structure is characteristic of many plants, including sunflowers and roses.
- However, it is important to note that being epigynous does not necessarily make a flower bisexual.
- Epigyny refers to the position of the ovary in relation to other floral parts, whereas bisexuality refers to the presence of both male and female reproductive structures within the flower.
- Hence, Reason R is true, but it does not provide a correct explanation for Assertion A.
Conclusion:
- Both the Assertion and the Reason are true, but the Reason does not correctly explain the Assertion.
- Therefore, the correct answer is option B: Both A and R are true, but R is not the correct explanation of A.
