Question

Flower of Fabaceae is
a) Complete, zygomorphic, and pentamerous
b) Complete, actinomorphic and trimerous
c) Incomplete, zygomorphic and trimerous
d) Incomplete, actinomorphic and pentamerous

Answer 1

Hint: The flower is the reproductive part of the plant and is responsible for the production of new progeny. The flower can be categorized as a complete flower or an incomplete flower. Depending on the number of the petals and sepals of the flower actinomorphic can be categorized into different categories.

Complete answer:
The flower present in the Fabaceae is zygomorphic in nature. These types of flowers can be divided into two equal parts when a line passes through the middle of the flower. They give mirror images. If the line passes from any other direction then they would not give the mirror image. The flower has the presence of five petals which makes it pentamerous in structure. The petals are arranged in the vexillary type of aestivation. In this type of aestivation, there is the presence of two wings and keels and a larger petal covering them. The flower is complete as it has the presence of both male and female reproductive organs. It has the presence of all the whorls of the petals present in it which also makes it a complete flower. This flower type is complete, zygomorphic and pentamerous.

So, the answer is ‘complete, zygomorphic and pentamerous’.

Note: The flowers of the Fabaceae are showy in nature and are entomophilous in nature which means they are pollinated by the insects. They are economically important flowering plants. They can be easily distinguished by their compound stipulated leaves. The ovary present is monocarpellary in nature and is superior. The androecium is present in diadelphous condition.
