Question

Hens egg is
A. An organ
B. A single cell
C. A tissue
D. None of the above

Answer 1

Hint: The egg is formed in the reproductive tract of a hen. The reproductive tract is further divided into two major parts- the ovary and the oviduct. The ovary is where the yolk is added. When the yolk reaches the right size, it is released from the ovary by a process called ovulation.

Complete answer:
The eggs are produced by female animals of many different species such as birds, reptiles, amphibians, a few mammals and fish and mostly these are eaten by humans. The eggs of the bird and reptile are composed of protective eggshell albumen which is the white portion of the egg and vitellus it is the yolk of the egg and composed within various thin membranes. The most commonly consumed eggs are chicken eggs.
The egg of a hen is a single cell structure inside the shell before the fertilization but after fertilization, the cells fused and divide into two cells inside the shell. The shape of an egg is the same as a prolate spheroid with one end larger than the other and has cylindrical symmetry along the long axis. An egg is surrounded by a thin, hard shell and the thin membranes exist inside the shell. The egg yolk is hung in the egg white by one or two spiral bands of tissue known as chalazae.
Hence, the correct answer is ‘B. A single cell’.

Note: The yolk of the egg and whole eggs store remarkable amounts of protein. The most commonly used bird eggs are those from the chicken, duck, and goose eggs.
