**Step-by-Step Solution:** 1. **Understanding Endosperm**: The endosperm is a tissue that provides essential nutrients to the developing embryo in seed plants. It is formed after fertilization and is crucial for the growth of the embryo. 2. **Nourishment Role**: The primary function of the endosperm is to supply the necessary food and energy required for the embryo's development. Without sufficient nourishment, the embryo would not be able to grow effectively. 3. **Sequence of Development**: The development of the endosperm occurs before that of the embryo. This sequence is essential because the embryo relies on the endosperm for its sustenance during its early stages of development. ...
