Where is the food for growing embryo inside eggs?

Here's a breakdown:

* Yolk: This is the yellow, nutrient-rich part of the egg. It contains proteins, fats, and other essential nutrients that the developing embryo needs to grow.

* Albumen (Egg White): This clear, protein-rich liquid surrounds the yolk and helps to protect it. It also provides some nutrients and water to the embryo.

* Chalaza: These are the twisted strands of protein that anchor the yolk in the center of the egg. They help to keep the yolk in place and prevent it from getting damaged.

So, the yolk is essentially the "food source" for the embryo within the egg.
