Question

A flower zygomorphic when
(a) Any transverse section divides it into two
equal halves
(b) Only one transverse section divides it into
two equal halves
(c) Every vertical section passing through its
centre divides it into two equal halves
(d) Only one vertical section passing through
its centre divides it into two equal halves

Answer 1

A flower zygomorphic when:

(d) Only one vertical section passing through its center divides it into two equal halves.

• Zygomorphic flowers are those that are bilaterally symmetrical.

• A zygomorphic flower can be divided into two equal halves only by one vertical plane.

• Some of the examples of zygomorphic flowers are Gulmohar, Cassia, etc.

Answer 2

The Correct Answer is (d)

Explanation:

    (D)The correct answer is'Only one vertical section passing through its centre divides it into two equal halves'

• Zygomorphic or two-sided is the point at which the bloom is isolated into equivalent parts just by one vertical plane, at that point it is called as a zygomorphic blossom, e.g., pea, bean, gulmohur, Cassia.  
• The blossoms of the plant Gulmohar are zygomorphic in nature. Canna, mustard, and hibiscus plants have blossoms which are actinomorphic.  
• Cassia has a place with the family Fabaceae.
• The blossoms right now unpredictable in light of the fact that the flower organs contrast in sizes.
• They show two-sided evenness thus they are zygomorphic. As a result of the inconsistency, the corolla likewise has petals that contrast from one another is sizes.
