Question: 105: The flowers are Zygomorphic in:
(a) Mustard
(b) Gulmohar
(c) Cassia
(d) Datura
(e) Chilly
Choose the correct answer from the options given below:
(1) (d), (e) Only
(2) (c), (d), (e) Only
(3) (a), (b), (c) Only
(4) (b), (c) Only
Answer: Option (4)
Explanation:
Zygomorphic flowers are those which can be divided into two equal halves only in one plane.
Gulmohar belongs to the family Fabaceae and shows zygomorphic symmetry.
Cassia also belongs to Fabaceae and has zygomorphic flowers.
Mustard flowers are actinomorphic, as they can be divided into equal halves in more than one plane.
Datura flowers are actinomorphic.
Chilly flowers are also actinomorphic.
Therefore, only Gulmohar and Cassia have zygomorphic flowers.
Hence, option (4) is the correct answer.
