GENERAL HISTOLOGY

Detailed explanation-1: -Egg cells are by far the largest cells produced by most organisms. In humans, they are several times larger than a typical body cell and about 10, 000 times larger than sperm cells.

Detailed explanation-2: -Eukaryotic cells are more complex and larger than prokaryotic cells. Animal and plant cells contain many organelles not found in prokaryotic cells.

Detailed explanation-3: -The largest known animal cell is the ostrich egg, which can reach about 5.1 inches wide and weighs around 1.4 kilogrammes. This is in stark contrast to the neuron in the human body, which is just 100 microns long.

Detailed explanation-4: -In most living animals, egg cells are vastly larger than sperm cells. In humans, for example, a single egg is 10 million times the volume of a sperm cell.

Detailed explanation-5: -The eggs of most animals are giant single cells, containing stockpiles of all the materials needed for initial development of the embryo through to the stage at which the new individual can begin feeding. Before the feeding stage, the giant cell cleaves into many smaller cells, but no net growth occurs.
