Question

Which is true for zygomorphic flowers?

• A. gulmohur
• B. tomato
• C. datura
• D. mustard

Answer 1

The correct option is C

datura

In symmetry, the flower may be actinomorphic (radial symmetry) or zygomorphic (bilateral symmetry).
When a flower can be divided into two similar halves only in one particular vertical plane, it is zygomorphic, e.g., pea, gulmohur, bean, Cassia.
When a flower can be divided into two equal radial halves in any radial plane passing through the centre, it is said to be actinomorphic, e.g., mustard, datura, chilli.
