Morphogenesis starts with

Options

A. Morulation
B. Blastulation
C. Gastrulation
D. None of these

Answer

**Step-by-Step Text Solution:**

1. **Understanding Morphogenesis**: Morphogenesis refers to the biological process that causes an organism to develop its shape and structure. It is a crucial part of developmental biology.

2. **Identifying the Starting Point**: Morphogenesis begins at the zygote stage. The zygote is the initial cell formed when a sperm cell fertilizes an egg cell.

3. **Zygote Development**: After fertilization, the zygote undergoes a series of cell divisions known as cleavage. This process leads to the formation of a multicellular structure.

4. **Formation of Germ Layers**: As development continues, the cells begin to differentiate and organize into layers known as germ layers (ectoderm, mesoderm, and endoderm), which will eventually give rise to different tissues and organs.

5. **Conclusion**: Therefore, morphogenesis starts with the zygote, which is the first step in the development of a new organism.
