Question

The part marked as ‘x’ in the given figure is

• A. Endosperm
• B. Thalamus
• C. Endocarp
• D. Mesocarp

Answer 1

The Correct Option is B

The given diagram shows a cross-section of a flower or fruit. The part marked as ‘x’ plays a role in the formation and structure of the fruit.

Let's analyze the options and determine which one correctly identifies the part marked as 'x':

1. Endosperm: This is a tissue produced inside the seeds of most flowering plants following fertilization. It is not typically a prominent external structure in a fruit.
2. Thalamus: The thalamus, also known as the receptacle, is the thickened part of a stem from which the flower organs grow. In some fruits, the thalamus becomes a part of the fruit structure, contributing to its development.
3. Endocarp: This is the innermost layer of the pericarp (fruit wall) which encases the seed. It appears to be more internal than the marked structure.
4. Mesocarp: This is the middle layer of the pericarp and typically forms the fleshy part of the fruit. It is also more internal than the marked structure.

Considering the location of 'x' in the diagram and the role of each part, the correct answer is Thalamus since 'x' refers to the expanded section at the base from where the flower organs or parts of the fruit would grow.
