Correct answer: A. Ectoderm & Endoderm
- A. Ectoderm & Endoderm
- B. Ectoderm & Mesoderm
- C. Mesoderm & Endoderm
- D. Mesoderm only
Explanation
In chick, development gives rise to ectoderm and endoderm. In chick embryos, the ectoderm and endoderm cells ultimately give rise to different tissues and organs. Ectoderm cells generate the skin and neural tissue. Endoderm cells become the lining of the gastrointestinal and the respiratory tracts.

About Growth and Development
Embryonic development covers fertilization, cleavage, formation of the blastula and gastrula, germ layers, organ formation and differentiation. Regeneration describes the replacement of lost tissues or body parts, whereas ageing involves gradual cellular and physiological changes linked to reduced repair, altered metabolism and declining organ function.
