Question

b
All living things or organisms are made of cells.
c
All cells arise spontaneously.
d
Cell is the basic structural and functional unit of life.

Answer 1

The statement that is NOT part of the "Cell Theory" is:

c. All cells arise spontaneously.

Cell Theory includes the following three main principles:

1. All living things are made of cells.
2. The cell is the basic structural and functional unit of life.
3. All cells arise from preexisting cells.

The idea that cells could arise spontaneously is not a part of Cell Theory and has been disproven by scientific evidence.
