Match List-I (Biological Structures) with List-II (Anatomical Origin and Evolutionary Pattern):
Choose the correct answer from the options given below:
| List-I | List-II |
|---|---|
| A. Sweet potato and potato | I. Homologous structures representing modification of axillary buds (Divergent evolution) |
| B. Thorns of Bougainvillea and tendrils of Cucurbita | II. Analogous structures where root and stem are respectively modified for storage (Convergent evolution) |
| C. Forelimbs of whales and bats | III. Analogous structures with different anatomical origins adapted for aquatic life (Convergent evolution) |
| D. Flippers of Penguins and Dolphins | IV. Homologous structures sharing common tetrapod ancestry adapted for different functions (Divergent evolution) |
Choose the correct answer from the options given below:
Options
- AA-II, B-I, C-IV, D-III
- BA-I, B-II, C-III, D-IV
- CA-II, B-IV, C-I, D-III
- DA-III, B-I, C-IV, D-II
Correct answer
A. A-II, B-I, C-IV, D-III
Step-by-step solution
Refer: NCERT | Class 12 | Page: 114 -115 | Paragraph: 1 - 1
Sweet potato is a root modification and potato is a stem modification. Both perform the same function of storage of food, making them analogous structures resulting from convergent evolution. Thus, A matches II.
Thorns of Bougainvillea and tendrils of Cucurbita are both modifications of axillary buds. They share a common anatomical origin but perform different functions (protection and climbing, respectively), making them homologous structures resulting from divergent evolution. Thus, B matches I.
Forelimbs of whales and bats share a common tetrapod ancestry and have the same basic skeletal structure but are adapted for different functions (swimming and flying). They are homologous structures resulting from divergent evolution. Thus, C matches IV.
Flippers of penguins (birds) and dolphins (mammals) have different anatomical origins but perform the same function of swimming. They are analogous structures resulting from convergent evolution. Thus, D matches III.
The correct matching is A-II, B-I, C-IV, D-III.
