Coconut has

Options

A. central liquid multinucleated endosperm
B. helobial endosperm
C. both (1) and (2)
D. exalbuminous endosperm

Answer

**Step-by-Step Solution:**

1. **Understanding the Types of Endosperm**:
- Endosperm is the tissue that provides nutrition to the developing embryo in seeds. There are different types of endosperm, including liquid, solid, and various structural forms.

2. **Identifying Coconut's Endosperm**:
- In the case of coconut, it is known to have a unique type of endosperm. The coconut endosperm is characterized by its liquid form, which is often referred to as coconut water.

3. **Defining Multinucleated Endosperm**:
- The coconut endosperm is multinucleated, meaning it contains multiple nuclei within a single cell. This occurs because the primary endosperm nucleus undergoes repeated divisions (karyokinesis) without cytokinesis, leading to many nuclei in a shared cytoplasm.

4. **Explaining the Formation Process**:
- During the development of the coconut, the primary endosperm nucleus divides repeatedly. However, cytokinesis (the division of the cytoplasm) does not occur, resulting in a multinucleated condition.

5. **Describing the Characteristics of Coconut Water**:
- The central liquid (coconut water) is rich in nutrients, including vitamins, minerals, sugars, and proteins. It is isotonic with body fluids, making it a popular natural energy drink.

6. **Conclusion**:
- Based on the characteristics and formation of the endosperm in coconuts, the correct answer to the question is that coconut has a central liquid multinucleated endosperm.

**Final Answer**: Coconut has a central liquid multinucleated endosperm.
