Consider the following list of plants: Mustard, Datura, Chilli, Pea, Gulmohur, Bean, Cassia, Canna How many of the above plants possess actinomorphic flowers?

Step-by-step solution

Actinomorphic flowers can be divided into two equal radial halves in any radial plane passing through the centre. According to NCERT, examples of plants with actinomorphic flowers are mustard, datura, and chilli. Thus, there are 3 such plants in the given list. Pea, gulmohur, bean, and Cassia exhibit zygomorphic (bilateral) symmetry, where the flower can be divided into two similar halves only in one particular vertical plane. Canna exhibits asymmetric (irregular) flowers, as it cannot be divided into two similar h
