According to cell theory, all cells carry out the functions needed to sustain life. That means all cells must contain A) DNA. B) a nucleus. C) organelles. D) a control center.

Not all cells have a nucleus, very simple cells do not. A nucleus is also a control center so not all cells have one either. All cells have to have DNA to reproduce. Organelles are not vital, for the DNA floats freely in cells with no nucleus. A is correct.

Organelles are not found in all cells before they can carry out their functions properly , but DNA is found in every cell, therefore all cells must contain DNA for the main purpose of reproduction .

Hence we can conclude that all cells must contain DNA to help the sustain life in the organism
