Multiple choice

Which of the following options best describes homologous organs?

  1. Organs which are similar in structure, origin and function

  2. Organs which are similar in structure and origin, but different in function

  3. Organs which are similar in function, but different in structure and origin

  4. Organs which are similar in function and structure, but different in origin
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Homologous organs are those which have similar internal structure and origin, but they are differently modified in various organisms to perform the functions that they require, e.g. forelimbs of a man to write; forelimbs of a horse to walk; forelimbs of a bird to fly; and forelimbs of a whale to swim. Thus, only (2) is correct. Option (3) is opposite of homologous organs because organs which are similar in function, but different in structure and origin are called analogous organs, e.g. wings of birds and bats.
