Which of the following is included in the cell theory?

A. All cells are so small that they can only be seen with a microscope.
B. All cells come from preexisting cells.
C. All organisms are made up of more than one cell.
D. Only animals are made up of cells.

Answer 1

Option B, 'All cells come from preexisting cells,' is the correct answer as it is included in the three main points of the cell theory.

Step-by-step explanation:

The question relates to the cell theory, which is a fundamental concept in biology. Among the options provided, the one that is included in the cell theory is B. All cells come from preexisting cells. The cell theory's major points are that all organisms are composed of cells, cells are the basic living units of organization in all organisms, and new cells are produced only from existing cells.

It is interesting to note that not all cells are too small to be seen without a microscope, as some can be visible to the n_aked eye, such as the egg of an ostrich. Moreover, the statement that all organisms are made up of more than one cell is incorrect because there are many single-celled organisms. Lastly, cells are not exclusive to animals; plants, fungi, bacteria, and archaea also consist of cells.

Answer 2

it's c

Step-by-step explanation:
