Excretory organs in Reptiles are____

• A. Nephridia
• B. Green glands
• C. Kidneys
• D. Flame cells

Answer 1

The Correct Option is C

To solve the problem, we need to identify the primary excretory organs in reptiles.

1. Function of Excretory Organs:
Excretory organs remove metabolic wastes from the body, primarily nitrogenous wastes like urea or uric acid.

2. Excretory Organs in Reptiles:
Reptiles excrete nitrogenous waste primarily in the form of uric acid, which helps conserve water. The organ responsible for this function in reptiles is the kidney. Reptilian kidneys are efficient in water reabsorption and produce a paste-like uric acid.

3. Other Options Explained:
- Nephridia: Excretory organs in annelids (e.g., earthworms).
- Green glands: Excretory organs in crustaceans (e.g., prawns).
- Flame cells: Found in flatworms (Platyhelminthes).

Final Answer:
The excretory organs in reptiles are \({\text{Kidneys}} \).
