Given below are two statements:
Statement I: In a floral formula ⊕ stands for zygomorphic nature of the flower, and G stands for inferior ovary.
Statement II: In a floral formula ⊕ stands for actinomorphic nature of the flower and G stands for superior ovary.
In the light of the above statements, choose the correct answer from the options given below:
Correct Answer :
Statement I is incorrect but Statement II is correct
Solution :
In a floral formula, specific symbols are used to convey the symmetry of the flower and the position of the ovary.
The symbol ⊕ is universally accepted to denote actinomorphic (radially symmetric) flowers. This means that the flower can be divided into similar halves by multiple planes passing through the central axis.
Conversely, a flower that is zygomorphic (bilaterally symmetric) is represented by a different symbol (often ⊖ or a half‑circle). Therefore, the claim in Statement I that “⊕ stands for zygomorphic nature” is false.
Regarding the ovary position, the letter G in a floral formula indicates a superior ovary**.** In a superior ovary, the ovary is situated above the point of attachment of other floral parts (sepals, petals, stamens). An inferior ovary is denoted by the letter g (lowercase). Hence, the assertion in Statement I that “G stands for inferior ovary” is also incorrect.
Putting these facts together, Statement II correctly states that “⊕ stands for actinomorphic nature of the flower and G stands for superior ovary.” Both parts of Statement II align with standard botanical notation.
Thus, the correct evaluation is:
• Statement I – Incorrect (⊕ is not for zygomorphic; G does not represent an inferior ovary).
• Statement II – Correct (⊕ denotes actinomorphic symmetry; G denotes a superior ovary).
