Question

Study following statements and choose the correct alternative.
(P) Those organs which have the same internal structure but different functions, are called homologous organs.
(Q) Organs which have different basic design but have similar appearance and carry out similar functions are called analogous organs.
(R) The impressions of dead plants or animals that lived in the past are known fossils.

• A. All the three (P, Q, R) statements are true
• B. Statements P and Q are true but R is false
• C. Only R is true
• D. All three statements are wrong

Answer 1

The correct option is A All the three (P, Q, R) statements are true

The organs which have the same structure but are involved in performing the different type of functions are known as homologous organs.

The organs which have similar functions but are structurally different are known as the analogous organs.

The fossils are the imprints, casts or molds of the dead animals and plants which existed in the past. These fossils are used for the study of the ancient organisms.

Thus, the correct answer is option A.
