Coconut water from a tender coconut is:

Options

A. immature embryo
B. free nuclear endosperm
C. inncermost layers of the seed coat
D. degenerated nucellus

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the nature of coconut water from a tender coconut. Specifically, it is inquiring whether it is a type of endosperm and what kind it is.

2. **Identifying Endosperm Types**: There are three main types of endosperm:
- **Nuclear Endosperm**: Characterized by karyokinesis (nuclear division) occurring without cytokinesis (cell division), resulting in multiple nuclei within a shared cytoplasm.
- **Cellular Endosperm**: In this type, both karyokinesis and cytokinesis occur, leading to the formation of distinct cells.
- **Halobial Endosperm**: This is a less common type that has characteristics of both nuclear and cellular endosperm.

3. **Coconut Water as Endosperm**: Coconut water is derived from the endosperm of the coconut seed. It is specifically classified as **nuclear endosperm** because it is formed through karyokinesis without cytokinesis, leading to a large number of nuclei in a single cell.

4. **Analyzing the Options**: The question may provide multiple-choice answers. The correct answer is:
- **Free Nuclear Endosperm**: This is the correct classification for coconut water.
- Other options such as immature embryo, innermost layer of the seed coat, and degenerated nucellus are incorrect.

5. **Conclusion**: Therefore, the coconut water from a tender coconut is classified as **nuclear endosperm**.
