In coconut , liquid nuclear endosperm is surrounded by white kernel which is

Options

A. integument /seed coat
B. Cellular endosperm
C. nuclear endosperm
D. filamentous mesocarp

Answer

To answer the question "In coconut, liquid nuclear endosperm is surrounded by white kernel which is?", we can follow these steps:

### Step 1: Understand the Structure of Coconut
Coconut is a unique fruit that contains both liquid and solid components. The liquid part is known as coconut water, which is the free nuclear endosperm. The solid part, which is the white kernel, is what we need to identify.

### Step 2: Define Endosperm
Endosperm is a tissue that provides nourishment to the developing embryo within seeds. It can be classified into different types based on its formation and structure.

### Step 3: Identify Types of Endosperm
There are three main types of endosperm:
1. **Nuclear Endosperm**: This type is formed when the primary endosperm nucleus divides to form multiple nuclei before cell walls are formed.
2. **Cellular Endosperm**: In this type, the first division of the endosperm nucleus is followed by the formation of cell walls, resulting in a cellular structure.
3. **Helobial Endosperm**: This is an intermediate type between nuclear and cellular endosperm.

### Step 4: Analyze the Options
The question provides several options:
- **Integuments**: These are protective layers surrounding the ovule and are not related to the kernel.
- **Cellular Endosperm**: This is the correct option as it refers to the white kernel surrounding the liquid nuclear endosperm in coconut.
- **Nuclear Endosperm**: This refers to the liquid part (coconut water) and not the kernel.
- **Flaminges**: This term does not apply in this context.
- **Mesocarp**: This refers to the fleshy part of the fruit, not the kernel.

### Step 5: Conclusion
Based on the analysis, the white kernel surrounding the liquid nuclear endosperm in coconut is identified as **cellular endosperm**.

### Final Answer:
The white kernel surrounding the liquid nuclear endosperm in coconut is **cellular endosperm**.
