Question

Zygomorphic flower is when

• A. Any vertical section passing through its center divides the flower into two equal parts.
• B. There is only one vertical section possible to cut flower into two equal parts.
• C. When cutting flower through any plane is not possible.
• D. All of the above.

Answer 1

Answer: (B)

There is only one vertical section possible to cut flower into two equal parts.

Zygomorphic flower is when there is only one vertical section possible to cut flower into two equal parts. When a flower can be divided by a single plane into two equal parts, it is zygomorphic, or bilaterally symmetrical, as in the snapdragon, orchid, and sweet pea. Any line drawn through the center will divide the flower into two identical halves. When at least one petal of the corolla is different, the flower has bilateral symmetry and is called as irregular or zygomorphic e.g., Violets, Viola; Violaceae.

Therefore, the correct answer is option B.
