Answer:
The correct option is B
Explanation:
A cell is the structural and functional unit of life. Cells "operate" on the basis of the cell theory. The cell theory states that
- cells are the structural and functional unit of life
- all living organisms are made up of one or more cells
- all cells come from pre-existing cells
From the above, it can be deduced that option B is part of the cell theory. When organisms are made up of one cell, they are called unicellular organisms and when organisms are made up of more than one cell, they are called multicellular organisms.
