Q51: Consider the following statements regarding the structural variations of multicarpellary pistils:
1. A multicarpellary pistil in which all the carpels are fused together into a single structure is termed syncarpous, as observed in Papaver (poppy).
2. When the multiple carpels of a flower remain completely free and unfused, the condition is termed apocarpous, classically observed in Michelia.
3. A syncarpous pistil typically develops into an aggregate fruit composed of many separate fruitlets.
Which of the above statements is/are correct?

Which of the above statements is/are correct?
✅ Correct Answer: A
The correct option is A. Statements 1 and 2 are correct, while Statement 3 is incorrect.
The pistil (gynoecium) is the female reproductive whorl.
When it consists of more than one carpel, it is termed multicarpellary.
The evolutionary and structural fusion of these carpels dictates future fruit development.
In a syncarpous ovary (e.g., Papaver, Hibiscus, Tomato), the carpels are fused, sharing a common ovary wall.
In an apocarpous ovary (e.g., Michelia, Rose, Lotus), the carpels remain completely distinct and separate from each other on the thalamus.
Statement 3 presents a reversed causal outcome.
A syncarpous pistil, being fused, develops into a single, simple fruit (like a single tomato). It is the apocarpous pistil, with its many separate ovaries, that develops into an aggregate fruit (an etaerio of fruitlets), where each individual carpel forms a distinct miniature fruit clustered together.
