The example that demonstrates that all cells come from pre-existing cells is an oak tree grows from the seed material in an acorn (option B).
The cell theory is the scientific theory that all living organisms are made of cells as the smallest functional unit.
One of the components of the cell theory is that all cells come from already existing cells i.e. new cells form from cells that are already in existence in a process of reproduction.
The example of this is a tree that grow from a germinating seed. Hence, option B is correct.

DNA in the nucleus of eukaryotic cells is collected into a chromatin.
A chromatin is a complex of nucleic acids (DNA or RNA) and proteins called histones which condense to form a chromosome during cell division.
In eukaryotic cells, it is found within the cell nucleus while in prokaryotes, it is found inside the nucleoid .
Its functions are;
1. to package DNA into a smaller volume to fit in the cell.
2. strengthen the DNA to allow mitosis and meiosis.
3. acts as a mechanism to control expression
The chromatin is easily recognized through staining. Its name literally means "colored material."
Answer: all of the above
