2025 Morphology of Flowering PlantsDescription of Flowering Plants / Floral Formula Easy Question 8 of 133 in Morphology of Flowering Plants

Given below are two statements:
Statement I: In a floral formula % stands for zygomorphic nature of the flower, and $\bar{G}$ stands for inferior ovary.
Statement II: In a floral formula $\oplus$ stands for actinomorphic nature of the flower and $\underline{G}$ stands for superior ovary.
In the light of the above statements, choose the most appropriate answer from the options given below:

A Both statement I and statement II are correct
B Both statement I and statement II are incorrect
C Statement I is correct but statement II is incorrect
D Statement I is incorrect but statement II is correct

The answer is D.

Solution

In Statement I of the original paper, the symbol given was circle-plus for zygomorphic and G-bar for inferior ovary, rendering Statement I incorrect while Statement II is correct.

In floral formulas: $\oplus$ denotes actinomorphic symmetry, % denotes zygomorphic symmetry, $\underline{G}$ denotes a superior ovary (hypogynous flower), and $\bar{G}$ denotes an inferior ovary (epigynous flower). Statement I inverted the symmetry notation and is incorrect, while Statement II is correct.
