For the human body, the female ovum.
Caulerpa is the largest single Cell organism. An unfertilized Ostrich egg is the largest single Cell; Ovums are single Egg Cells. Actually the largest single cell in the world is the giraffe neuron in a hind leg of the giraffe.
The single largest cell is that of an egg

An ostrich egg.
Extinct: Xenophyophores . Living: Unfertilised ostrich eggs.
yes edit: No, even though that is what social media would have you believe. In reality the egg yoke is simply food for a microscopic normal sized cell. The yoke itself does not live nor act like a cell at all. Also even if you were to assume that by a vauge definition it were a cell (the same definition that would interpret my bladder as a cell) then yes it would be an abnormaly large cell, but not the largest. There is a kind of plant growing in south america which can get multiple meters in length. So im sorry but it is not the largest single cell, but that would be cool
The largest single cell today would be the ostrich egg. The previous champ would probably have been the egg of the elephant bird of Madagascar.
The ribosomes.
The largest single-cell organism is the marine microorganism called Thiomargarita namibiensis. It can reach up to 0.75 mm in diameter, making it visible to the naked eye.
No, each egg cell is a single haploid cell. Once it is fertilised it divides into many different cells, which later on forms the foetus.
an egg cell *** An egg (such as the chicken egg) is not one cell. The largest cells are usually neurons (some motor neurons can go from the spine or brain till the tip of the toes, so in larger animals that can mean a cell which is more than a meter long.
Caulerpa, a tropical alga, consists of only one cell with many nuclei, making them the biggest single cells in the world. A species in the Mediterranean can have a stolon more than 3 metres (9 feet) long, with up to 200 fronds.
