Question

Flower is zygomorphic in
(A) Mustard
(B) Tomato
(C) Gulmohar
(D) Datura

Answer 1

Hint: Zygomorphic flowers are those flowers which have bilateral symmetry and the petals can be divided only in one way such that they form mirror images of each other.

Complete answer:
Zygomorphic flowers facilitate more precise contact with pollinators, guide pollinator behavior, and exclude less effective pollinators. However, to our knowledge, the basic idea that zygomorphic flowers are visited by a smaller subset of available pollinators has not been broadly evaluated. Differential development of one or two of the three organs within a whorl inevitably emphasizes one plane of symmetry.

Zygomorphy (monosymmetry) has evolved more than once in monocotyledons. Stamen suppression is a widespread aspect of zygomorphic and conforms to two broad categories of pattern. Flowers can be divided into two equal halves only in one vertical plane passing through its centre. Example: Gulmohar.

Gulmohar is an ornament plant also known as flame tree. Gulmohar is well known for its beautiful flowers. But it also has some medicinal properties like Anti-diabetic activity, Antibacterial activity, Anti-diarrheal property, Hepatoprotective/Cytotoxic property, Antimicrobial activity, Anti-Inflammatory activity. It belongs to the family Leguminosae.

Tree or royal poinciana or the peacock flower tree (Delonix regia). This plant was previously
placed in the genus Poinciana, named after Phillippe de Longvilliers de Poincy, who is credited with introducing the plant to the Americas

Therefore, from the above explanation, the correct option is (C) Gulmohar.

Note: Please do not get confused between the terms zygomorphic and actinomorphic flowers,
1. Zygomorphic flowers - They are bilaterally similar and can be divided equally only in one plane
2. Actinomorphic flowers - They are radially symmetrical and they can be divided into two equal parts along any diameter.
