Question

Match the morphological features in Group I with their corresponding descriptions given in Group II.

Group I	Group II
P. Hyponome	3. Long tubular structure
Q. Myophore	4. Shaft with a head
R. Hypostome	1. A large plate
S. Myostracum	2. Irregular prismatic crystals

• A. P-3, Q-4, R-1, S-2
• B. P-3, Q-2, R-4, S-1
• C. P-2, Q-4, R-3, S-1
• D. P-1, Q-3, R-2, S-4

Hint:

To match morphological features with descriptions, focus on identifying the shape and structure of the feature, such as tubular, prismatic, or plate-like structures.

Answer 1

The Correct Option is A

Step 1: Understand the Morphological Features.
- Hyponome refers to a structure that is typically long and tubular, hence matches with 3. Long tubular structure.
- Myophore is related to a prismatic crystal structure, corresponding to 2. Irregular prismatic crystals.
- Hypostome is a structure with a shaft and a head, making it match with 4. Shaft with a head.
- Myostracum is a large plate-like feature, corresponding to 1. A large plate.
Thus, the correct matching is: \[ \boxed{\text{P-3, Q-4, R-1, S-2}} \] Final Answer: \[ \boxed{\text{P-3, Q-4, R-1, S-2}} \]
