Why (A) Brassica is correct: Flowers of Brassica (mustard family) exhibit radial symmetry, meaning they can be divided into two equal halves by any vertical plane passing through the center. This type of symmetry is also known as actinomorphic.
Why other options are wrong:
- (B) Trifolium: Trifolium (clover) has zygomorphic (bilateral) flowers.
- (C) Pisum: Pisum sativum (pea) has zygomorphic (bilateral) flowers.
- (D) Cassia: Cassia also typically has zygomorphic (bilateral) flowers.
Common Mistake: Students often confuse actinomorphic and zygomorphic symmetry. Remember that most common garden flowers like rose, lily, and mustard are actinomorphic, while pea, bean, and gulmohar are zygomorphic.
NEET Tip: Think of a star or a wheel for radial symmetry (actinomorphic) and a human face or a butterfly for bilateral symmetry (zygomorphic).
Correct Answer: (A)
