Question 12
A basket of vegetables contains carrot, potato, radish and tomato. Which of them represent the correct homologous structures?
(a) Carrot and potato
(b) Carrot and tomato
(c) Radish and carrot
(d) Radish and potato
(c) Radish and carrot
Radish and carrot, since they are similar in basic fundamental structure and evolutionary origin. Homologous structures are similar in origin but perform different functions. Both carrots, as well as radish, are underground roots but considering all other aspects of homology, they belong to the homologous category.
a. potato is the stem and carrot is root
b. potato is stem and radish is root
c. tomato is fruit and carrot is root
So, they differ in structure and nature and hence are not homologous organs.
