Question

Identify the parts P, Q, R, S in the figure given below and select the option in the correct order.

• A. P - Seed, Q - Thalamus, R - Mesocarp, S - Endocarp
• B. P - Thalamus, Q - Seed, R - Endocarp, S - Mesocarp
• C. P - Seed, Q - Thalamus, R - Endocarp, S - Mesocarp
• D. P - Thalamus, Q - Seed, R - Mesocarp, S - Endocarp

Hint:

The thalamus is the supporting base of the flower, while the mesocarp and endocarp are the middle and innermost layers of the fruit, respectively.

Answer 1

The Correct Option is C

Step 1: Understanding the parts of a flower.
The figure shows the anatomy of a fruit. The thalamus is the part of the flower that connects the ovary, stem, and petals. The mesocarp refers to the middle layer of the fruit, while the endocarp is the innermost layer surrounding the seed.
Step 2: Analyzing the options.

• (A) P - Seed, Q - Thalamus, R - Mesocarp, S - Endocarp: Incorrect. The seed is typically surrounded by the endocarp, not the thalamus.
• (B) P - Thalamus, Q - Seed, R - Endocarp, S - Mesocarp: Incorrect. The thalamus is not the part inside the fruit.
• (C) P - Seed, Q - Thalamus, R - Endocarp, S - Mesocarp: Correct. The seed (P) is inside the endocarp (R), and the thalamus (Q) supports the fruit. The mesocarp (S) surrounds the seed.
• (D) P - Thalamus, Q - Seed, R - Mesocarp, S - Endocarp: Incorrect. The thalamus cannot be part of the fruit's internal layers.

Step 3: Conclusion.
The correct answer is (C) P - Seed, Q - Thalamus, R - Endocarp, S - Mesocarp.
Final Answer: (C) P - Seed, Q - Thalamus, R - Endocarp, S - Mesocarp.
