NEET UG BIOLOGY MCQ: MORPHOLOGY OF FLOWERING PLANTS

Correct Answer + Core Reason: Either (a) or (b). Both Thalamus and Receptacle can refer to the pedicel of the flower.

Step-by-Step Solution:

Step 1: Define the terms:
- Pedicel: The stalk of a flower.
- Thalamus: The expanded end of the pedicel where floral organs are attached; also called the receptacle.
- Receptacle: The expanded end of the pedicel where floral organs are attached; also called the thalamus.

Step 2: Analyze the options:
- Thalamus and receptacle are essentially the same structure.

Step 3: Therefore, the pedicel of a flower can be referred to as either the thalamus or the receptacle.

Why other options are wrong:
- Option A: Thalamus alone is not entirely correct as receptacle is also used.
- Option B: Receptacle alone is not entirely correct as thalamus is also used.
- Option C: Both (a) and (b) is not entirely correct because the question asks what the pedicel is called, not the structure that holds the floral parts.

Key Concepts:
- Flower morphology
- Thalamus/Receptacle
- Pedicel

Memory Aids:
- Thalamus and receptacle are interchangeable terms.

Quick Tips:
- Understand the basic structure of a flower and the terms associated with it.
