Question Details

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:

Options

A

Both Statement I and Statement II are incorrect

B

Statement I is correct but Statement II is incorrect

C

Statement I is incorrect but Statement II is correct

D

Both Statement I and Statement II are correct

Show Answer

Correct Answer :

Option C

Statement I is incorrect but Statement II is correct

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).
