Egg Sandwich

Q: 1. for what purpose do people use egg yolks? for what purpose do developing chicks use egg yolks?
2. is a egg an organelle, a cell, a tissue, organ or organ system?
A: Answer 1: If I understand your question correctly, people use egg yolks as a food source. Developing chicks also use the yolk in an egg as their food (energy) source. Remember, a developing chick has no other outside source of food, unlike mammals.
Answer 2: A chicken egg has an individual cell plus food source enclosed within the shell. If it is a fertilized egg - not all chicken eggs are fertile - the cell has half of its chromosomes from the mother and half from the father - the two halves added together make up all the requirements for the chicken that will develop. The bulk of a chicken egg, however, is egg yolk and albumin - the cell is too small to be seen with the naked eye.
