Question

Which two of these vegetables correctly represent the homologous structures?
Potato Tomato, Radish, Brinjal, carrot, Bottle- ground
A. Carrot and Tomato
B. Potato and Brinjal
C. Radish and Carrot
D. Radish and Bottle-ground

Answer 1

The homologous structures are the parts of the plants that are similar in the origin as well as may perform different functions. The radish and the carrot are the examples of the homologous structures. Carrot and radish both are conical root structures and include different nutrients as well as have the same function of storage.

Complete answer:
Carrot - The carrot is a root vegetable, normally orange in color, though they can be purple, black, red, white, as well as yellow cultivars exist. They are said to be domesticated form of the wild carrot, Daucus carrot, native to Europe as well as South-western Asia.
