Question

The largest biological cell is often cited as the .......... egg.
A) Human
B) Bird
C) Ostrich
D) Snake

Answer 1

The egg is the single- celled structure. A cell can be defined as the structural and fundamental unit of life. The study of cells from its basic structure to the functions of every cell organelle is called the Cell Biology. Robert Hooke was the first Biologist who discovered the cells.

Complete answer:
Human egg is larger than any other cell in the human body, at about hundred microns in diameter, about the same size as a strand of hair. That means you could see an egg cell with the naked eye. Egg cells are about four times the size of skin cells and about twenty times the size of sperm.
Bird egg size tends to be proportional to the size of the adult bird, Kiwis have disproportionately large eggs, up to twenty percent of the female's body weight.
The egg of an ostrich is the largest cell in the world and it measures up to fifteen to seventeen centimeters.
The size of a snake egg can be from one inch to four to five-inch python eggs. Most eggs that have a rubbery shell and are over an inch big are usually considered as snake eggs.

Therefore we can say that option C) is the correct answer which is ostrich.

Note:
The egg cell or the ovum, is the female reproductive cell or the gamete in most anisogamous organisms which means the organisms that reproduce sexually with a larger female gamete and a smaller male one. The term is commonly used when the female gamete is not capable of movement which is non-motile.
