Question

Study the different conclusions drawn by students of a class on the basis of observations of preserved/available specimens of plants and animals. (1)I. Potato and sweet potato are analogous organs in plants.II. Wings of insects and wings of birds are homologous organs in animals.III. Wings of insects and wings of bats are analogous organs in animals.IV. Thorns of citrus and tendrils of cucurbita are analogous organs in plants.The correct conclusions are:(A) I, and II(B) II and IV(C) I and III(D) III and IV

Answer 1

(C)Analogous organs are those which do not share a common ancestry but perform common function.Hence, wings of insects and wings of bats are analogous organs in animals.Hence, Potato and sweet potato are analogous organs in plants.

Answer 2

(C) I and III

Explanation:

• Homologous organs are the organs which have the same structure and can be related to the same evolutionary lineages. But the analogous organs are those which have different structures which perform same functions in the distinct organisms.
• The tuber of potato and sweet potato have the same function that is the storage of food. Thus these are the analogous structures.
• Wings of insects and that of bats have different structures and these structures do not possess the common embryonic origin and thus these cannot be related to common ancestor or common evolutionary lineages. These are the analogous structures.
