Can cells be seen by naked eye?

Most of the cells cannot be seen through our naked eyes, we need a magnifying glass to see them

But  few cells can be seen through our naked eyes

What is the size of the cell

Cells are usually very small (microscopic in nature) which means they cannot be seen through the naked eyes

Size of the cell does not relate to the size of the body

It is related to the function it performs
