Observing a macro cell: an egg! (5th Grade)

Hello boys and girls!

In 5th Grade, we are learning about the cells.

Most of the cells are so tiny that are invisible to the human eye; we need a microscope to see them.

But, if we look at an unfertilized egg, we can see a cell! In fact, the YOLK (yellow part) is a single cell.

We could identify:

  • the cytoplasm (yellow)
  • the membrane (by smashing soflty the yolk)
  • the nucleus (a white spot in the cytoplasm)
