Describe the structure of hens egg ?
An egg from a hen consists of approximately 2/3 egg white and 1/3 egg yolk. The shell is built of 8-10,000 pores, which ensures that oxygen can penetrate and CO2 and other gases can escape. The shell represents about 10 % of the weight of the egg and consists mainly of calcium carbonate and calcium phosphate.

Describe the structure of hens egg ?
Structure of Hen's Egg


A hen's egg is a common food item that is packed with nutrients such as protein, vitamins, and minerals. The eggshell is made up of calcium carbonate and is porous, allowing air and moisture to pass through. The egg has several parts, each with its own structure and function.


Eggshell


  • The eggshell is the hard outer covering of the egg. It is made up of calcium carbonate and is porous.

  • The pores allow air and moisture to pass in and out of the egg. This is important for the developing embryo to breathe and for the egg to maintain its freshness.

  • The eggshell also protects the egg from damage and helps to maintain its shape.



Egg White (Albumen)


  • The egg white, also known as the albumen, is the clear liquid that surrounds the yolk.

  • It is made up of water and protein and contains no fat or cholesterol.

  • The egg white provides a protective layer around the yolk and helps to cushion it.

  • It also provides a source of protein for the developing embryo.



Egg Yolk


  • The egg yolk is the yellow part of the egg that is surrounded by the egg white.

  • It contains fat, protein, and cholesterol, as well as vitamins and minerals.

  • The egg yolk provides a source of nutrients for the developing embryo.

  • It also provides flavor and richness to foods that contain eggs.



Chalaza


  • The chalaza is the thick, twisted cord that runs through the egg white and attaches the yolk to the shell.

  • It helps to keep the yolk in the center of the egg and prevents it from moving around.



Germinal Disc


  • The germinal disc is a small, white spot on the surface of the yolk.

  • It is where the embryo develops if the egg is fertilized.

  • If the egg is not fertilized, the germinal disc is absorbed by the yolk and the egg is not able to develop into a chick.
