Some surprising science fact that many people don't know, an animal egg (chicken, birds, etc) is a single cell, so there's a huge variability in the weight of a cell.

There are some very large single celled organisms that aren’t eggs. E.g.:

Even some bacteria can grow to visible size:

There are some other examples here:

I found this claim unbelievable, but it is mostly true. It isn't quite the whole egg, it is just the yolk. But that's still a very large cell!

It's analogous to the mammalian egg, but a lot bigger. (And IIRC the egg is the largest cell in humans.)
And the smallest is the sperm.
Which, ironically, are both only haploid.
i guess if it's fertilized then it will soon have more cells
