Question

Choose the incorrect statement.

• A. Calyx and corolla are accessory organs while androecium and gynoecium are reproductive organs
• B. The flower of mustard plant shows actinomorphic symmetry
• C. The flower of pea plant shows actinomorphic symmetry
• D. Canna has asymmetric flowers

Answer 1

The correct option is C The flower of pea plant shows actinomorphic symmetry

A typical flower has calyx, corolla, androecium and gynoecium. Calyx and corolla are accessory organs while androecium and gynoecium are reproductive organs present in a flower.
A flower may have actinomorphic (radial symmetry) or zygomorphic (bilateral symmetry). Actinomorphic flowers are found in mustard, datura, chilli and zygomorphic van be seen in pea, gulmohur, bean, Cassia. A flower is asymmetric (irregular) if it cannot be divided into two similar halves by any vertical plane passing through the centre, as in Canna.
