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
Answer:(c)
Solution:
The structures that are similar in related organisms because they were inherited from a common ancestor are Homologous structures. These may or may not have the same function as in the descendants.
Radish and carrot represent homologous structures as they have the same structure (or basic design) though they are different species. Both store energy and have modified roots.
Therefore, option (c) is correct.
