Here are the essential concepts you must grasp in order to answer the question correctly.
Nutritional Composition of Egg Yolk
Egg yolks are rich in fat, protein, and cholesterol, which are essential nutrients for the developing embryo. The high fat content provides a concentrated source of energy, while proteins are crucial for growth and development. Cholesterol plays a vital role in cell membrane formation and hormone production, making it necessary for the chick's early development.

Role of Lipids in Development
Lipids, primarily found in the form of fats in egg yolk, serve as a significant energy reserve for the developing chick. They are metabolized to provide the energy needed for cellular processes and growth. Additionally, certain lipids are involved in the formation of cell membranes and are precursors for important signaling molecules.

Importance of Protein in Embryonic Development
Proteins in egg yolk are composed of amino acids, which are the building blocks for the chick's tissues and organs. During the early stages of development, the embryo relies on these proteins for cellular structure, enzyme function, and overall growth. The presence of high-quality proteins ensures that the developing chick has the necessary resources to form vital biological structures.
