CELL THEORY

Cells are the foundation of all life and arise from other cells.

Inside all cells are active structures called organelles.

The activities that occur inside cells are called cellular processes.

What is wrong with this statement?

Prokaryotic cells arise from air and water. They are

more complex versions of eukaryotic cells since

they have a nucleus with circular DNA and include

all bacteria and fungi.
