The function of endosperm is to :

Options

A. develop into the fruit
B. provide water to the embryo
C. provide nutrients to the embryo
D. provide a protective coating for the embryo

Explanation

To answer the question about the function of endosperm, we can break down the information as follows:

### Step-by-Step Solution:

1. **Understanding Endosperm**:
- Endosperm is a tissue produced in the seeds of flowering plants (angiosperms) during fertilization. It is formed from the fusion of a sperm cell with two polar nuclei in the embryo sac.

2. **Role in Seed Development**:
- The primary role of the endosperm is to provide nourishment to the developing embryo within the seed. This nourishment is crucial for the growth of the embryo until it can establish itself and begin photosynthesis.

3. **Nutritional Functions**:
- The endosperm stores various nutrients, including carbohydrates, proteins, and fats, which are essential for the growth and development of the embryo.

4. **Water Supply**:
- While the endosperm does help in providing some water to the embryo, its main function is more focused on nutrition rather than solely supplying water.

5. **Protection**:
- The endosperm does not provide a protective coating for the embryo; that role is typically fulfilled by the seed coat.

6. **Conclusion**:
- Therefore, the function of the endosperm is primarily to provide nutrition to the embryo, which supports its growth until it can sustain itself.

### Final Answer:
The function of endosperm is to provide nutrition to the embryo.
