Question

A chicken egg is a single cell. Why is it so much bigger than other cells?

A its function is to hold an embryo
B it only divides once a year
C to provide food for humans
D none of the above

Answer 1

D. None of the above.
An egg is a single cell because this cell forms into many after a few months from a chick hatching from the egg.

Answer 2

D. none of the above

Step-by-step explanation:

The egg itself is not a cell, but its egg yolk is considered a macrocell (which can be seen with the naked eye). This macrocell is nothing more than an oocyte II when there is no fertilization, or an embryo where no fertilization has occurred.

Regardless of fertilization, the egg forms in domestic chickens, roughly, as occurs in women monthly ovulation (menstruation). Thus, if the breeder's goal is to produce eggs for consumption, then only unfertilized eggs will be obtained, so the macrocell is formed because there was no fertilization.
