Answer 1

Answer: (C), (D)

The correct options are
C

Cells do not arise from pre-existing cells.

D

Some living organisms are not made up of cells

The cell theory was prepared methodically by the observations and inferences of two German scientists, Schleiden and Schwann. They concluded that all living organisms are made up of one or more cells. Rudolf Virchow, in 1855, explained that cells divide and give rise to new cells and gave the theory its final shape. Hence, the postulates of cell theory were laid as follows:

• Cells arise from pre-existing cells.
• The cell is the basic functional unit of life.
• All living organisms are made up / constitute of one or more cells.
