State whether the following statements are true or false:
c) Egg laid after fertilisation is made up of a single cell.

Answer

To determine whether the statement "Egg laid after fertilisation is made up of a single cell" is true or false, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Fertilization**: Fertilization is the process where the male gamete (sperm) and the female gamete (egg) fuse together. This fusion results in the formation of a zygote.

2. **Formation of the Zygote**: After the sperm fertilizes the egg, a single cell called a zygote is formed. This zygote contains genetic material from both the male and female gametes.

3. **Characteristics of the Zygote**: The zygote is indeed a single cell. It has one nucleus that contains the combined genetic material from both parents.

4. **Development from the Zygote**: The zygote will undergo multiple divisions (cell division) to eventually develop into a multicellular organism. However, at the moment of fertilization and immediately after, it is a single cell.

5. **Conclusion**: Since the statement refers to the egg laid after fertilization being a single cell, and since the zygote is a single cell, the statement is true.

### Final Answer:
The statement "Egg laid after fertilisation is made up of a single cell" is **True**.
