Question

question 8
what is not part of the cell theory?
all cells contain dna
cells are the smallest unit of life
all organisms are multicellular
all cells come from pre - existing cells

Explanation:

The cell theory states that cells are the basic unit of life, all living things are made of cells, and all cells come from pre - existing cells. There are unicellular organisms, so the statement that all organisms are multicellular is incorrect. Also, while most cells have DNA, there are some exceptions like mature red blood cells in mammals which lose their nuclei and DNA. But the main incorrect statement among these related to cell - theory concepts is about the multicellularity of all organisms.

Answer:

C. all organisms are multicellular
