From which part of blastocyst does an embryo develop

Explanation

**Step-by-Step Solution:**

1. **Understanding the Blastocyst**: The blastocyst is a structure that forms during the early development of mammals, including humans, after fertilization occurs.

2. **Formation of the Blastocyst**: After fertilization, the zygote undergoes several rounds of cleavage (mitotic divisions), leading to the formation of a morula, which is a solid ball of cells. The morula then develops into the blastocyst.

3. **Components of the Blastocyst**: The blastocyst consists of two main types of cells:
- **Trophoblast**: This is the outer layer of cells. Its primary role is to provide protection to the developing embryo.
