The correct statement about the cell theory is:
a. All cells come from other cells
Explanation:
1. The cell theory states that all living organisms are composed of cells. This means that cells are the basic structural and functional units of all living things.
2. One of the key principles of the cell theory is that new cells are formed from pre-existing cells. This concept is known as cell division, where a parent cell divides to give rise to two or more daughter cells.
3. Therefore, the statement "All cells come from other cells" accurately represents this fundamental aspect of the cell theory.
In summary, cells do not spontaneously generate but rather originate from existing cells through the process of cell division, aligning with the principle of the cell theory.
