Hint: The floral symmetry is used to check whether the flower is divided into two or more identical sections. Flowers that lack symmetry are known as asymmetric flowers and other types of symmetry are known as radial and bilateral symmetry. The flower with radial symmetry is Ranunculus.
Complete answer: Flowers are said to be actinomorphic if they can be divided into three or more identical sections. Actinomorphic flowers are said to have radial symmetry. The division of the flower into symmetrical halves by several longitudinal planes may or may not be possible. Examples of actinomorphic flowers are lily and buttercup.
a) Zygomorphic flowers are those that can be divided into two mirror images by a single plane. These types of flowers are also said to have bilateral symmetry. Examples of zygomorphic flowers are orchids.
Flowers that do not exhibit any type of symmetry are known as asymmetric flowers. Examples include Canna indica.
b) In cyclic, the floral arrangement is of three types. Here, floral parts are arranged in definite whorls around the axis, e.g. mustard. Other types include acyclic, in which the floral arrangement is spiral and not a whorl type and spirocyclic, in which some parts are spiral and some are whorl.
Hence, the correct answer is option B.
Note: A flower is the reproductive structure of flowering plants. Its main function is to facilitate reproduction. It can be unisexual or bisexual. The male reproductive structure of a flower is called androecium, while the female reproductive part is called the gynoecium.
