Moreover, what is the largest cell?
The largest cells is an egg cell of ostrich. The longest cell is the nerve cell. The largest cell in the human body is female ovum. Smallest cell in the human body is male gametes, that is, sperm.
Why are there no large single celled organisms?
But, as the balloon inflates, the volume increases much faster than the surface area. There are no massive single celled organisms because diffusion alone acts too slowly to deliver nutrients around a massive cell. Multicellular organisms have evolved ways of transporting bulk amounts of stuff around their bodies.
