Prokaryotic and Eukaryotic Cells

1.- COMPLETE THE STATEMENTS

1.- Living things are made of ...............and cell products. In other words, we consider the cell to be a ...................fundamental structural aspect of life.

2.- Cells in our world come in ...............basic types, prokaryotic and eukaryotic

3.- "Karyose" comes from a Greek word which means "kernel," as in a kernel of grain.

4.- This is far from the only difference between these two cell types, however.
