Q.50 Match List I with List II
| LIST I Order of class Reptilia |
LIST II Representative animal |
||
|---|---|---|---|
| A. | Squamata | I. | Tortoise |
| B. | Crocodilia | II. | Tuatara |
| C. | Chelonia | III. | Gharial |
| D. | Rhynchocephalia | IV. | Monitor lizard |
Choose the correct answer from the options given below:
- A-I, B-IV, C-III, D-III
- A-II, B-I, C-III, D-IV
- A-IV, B-II, C-III, D-I
- A-IV, B-III, C-I, D-II
Reptilia class orders are matched with representative animals based on standard zoological classification. Option 3 correctly pairs each order with its hallmark species for exams like GATE Life Sciences.
Question Breakdown
List I (Orders of Reptilia):
-
A. Squamata: Lizards and snakes (largest order).
-
B. Crocodilia: Crocodiles, alligators, gharials.
-
C. Chelonia: Turtles and tortoises (also called Testudines).
-
D. Rhynchocephalia: Tuataras (primitive New Zealand reptiles).
List II (Representative Animals):
-
I. Tortoise
-
II. Tuatara
-
III. Gharial
-
IV. Monitor lizard
Correct Matches
-
A-IV: Squamata includes monitor lizard (Varanus).
-
B-III: Crocodilia includes gharial (Gavialis gangeticus).
-
C-I: Chelonia includes tortoise (Testudinidae family).
-
D-II: Rhynchocephalia represented solely by tuatara (Sphenodon).
Answer: Option 3 (A-IV, B-III, C-I, D-II)
Option Analysis
-
Option 1 (A-I, B-IV, C-III, D-III): Wrong. Squamata not tortoise (I); Crocodilia not monitor lizard (IV); duplicate III invalid; Rhynchocephalia not gharial (III).
-
Option 2 (A-II, B-I, C-III, D-IV): Wrong. Squamata not tuatara (II); Crocodilia not tortoise (I); Chelonia not gharial (III); Rhynchocephalia not monitor lizard (IV).
-
Option 3 (A-IV, B-III, C-I, D-II): Correct. All matches align with taxonomic standards.
-
Option 4 (A-IV, B-II, C-III, D-I): Wrong. Crocodilia not tuatara (II); Chelonia not gharial (III); Rhynchocephalia not tortoise (I).
Reptilia orders matching with representative animals is key for zoology exams like GATE Life Sciences. This guide details Squamata, Crocodilia, Chelonia, and Rhynchocephalia classifications, solving Q.50 accurately.
Squamata Overview
Squamata, the scaled reptiles, encompasses lizards (like monitor lizard) and snakes. Over 10,000 species; features overlapping scales, flexible jaws.
Crocodilia Features
Crocodilia includes large aquatic predators like gharial (long-snouted fish-eater). Four-chambered heart; powerful tails for swimming.
Chelonia Characteristics
Chelonia (Testudines) features tortoises with bony shells for protection. Land-dwelling; retractable heads in some species.
Rhynchocephalia Details
Rhynchocephalia survives only as tuatara in New Zealand. “Living fossil” with primitive traits like pineal eye.
