D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: D
## CONCEPT FRAMEWORK
 **Primary Concept**: Plant Anatomy and Embryology
 **Related Topics**: Coconut structure, endosperm development, seed structure
 **Prerequisites**: Basic understanding of plant tissues and seed development.
## SOLUTION PATHWAY
**Given Information**:
  The question asks about the nature of coconut water in a tender coconut.
  The options represent different parts of the coconut fruit.
**Method & Steps**:
 1. Identify the structure of a coconut fruit.
  Reasoning: A coconut is a drupe fruit. It has three layers: exocarp (outer skin), mesocarp (fibrous husk), and endocarp (hard shell). Inside the endocarp is the seed which contains the endosperm.
 2. Understand the development of coconut endosperm.
  Working: In coconut, the endosperm develops through free nuclear divisions.  Initially, the endosperm is a liquid milky substance (coconut water) which is a free nuclear endosperm. Later, cell walls form within this liquid, creating the solid coconut meat (endosperm).
 3. Relate the coconut water to the given options.
  Key Point: The coconut water is the liquid endosperm at a young stage of development. 
 3. Final step
  Result: The coconut water in a tender coconut represents the free nuclear endosperm.
  Verification: This is consistent with the development of coconut endosperm. 
 ## OPTION ANALYSIS
[A] :x: Endocarp is the hard shell of the coconut, not the liquid inside.
[B] :x: The fleshy mesocarp is the fibrous husk surrounding the hard shell.
[C] :x: Free nuclear proembryo is an early stage of embryo development; coconut water is not the embryo.
[D] ✓: Free nuclear endosperm accurately describes the coconut water in its early stage of development before cell wall formation.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing endosperm with embryo:  Remember the endosperm is the nutritive tissue, providing food for the developing embryo.
  2.Incorrectly identifying the layers of the coconut fruit:  Understanding the structure of a drupe is crucial.
 **Quick Tips**:
  1.Visualize the layers of a coconut fruit and their respective contents.
  2. Remember that the coconut water is a liquid form of the endosperm, which later develops into the solid coconut meat.
