"All" is a complicated word in Biology as there are almost always exceptions to every rule. Not all cells have a nucleus. Red blood cells in humans don't, though they do in some other animals such as birds. Sieve tube element cells in plants don't either. Prokaryotes, which means 'primitive nucleus' such as bacterial cells technically don't have a proper nucleus as in having a membrane sheltering their genetic material.

What is cell theor?
Cell theory is a principle in Biology the states what happens in a cell. Cell theory states that every living organisms consists of cells, and everything needs cells to survive.
What did Robert brown make to the cell theory?
Robert Brown's discovery of the cell nucleus in 1831 contributed to the cell theory by elucidating the presence of a central structure within cells. This observation further supported the idea that cells are fundamental units of life and laid the foundation for the understanding of cell structure and function.
Is the germ theory and the cell theory the same?
No, the germ theory and the cell theory are not the same. The germ theory explains that certain microorganisms can cause diseases, while the cell theory states that all living organisms are composed of cells as the fundamental units of structure and function.
What does the cell theory state that all cells come from?
The cell theory states that all cells come from pre-existing cells. This means that new cells are produced through the division of existing cells.
What are some examples of Cell theory?
If cell theory states that all living things are made up of cells, then anything that is not alive is not an example. For example, a table is not made of cells.
Where does the cell theory states that cells come from?
other cells

What states all organisms are made up of cells?
The cell theory states that all living organisms are composed of one or more cells, cells are the basic unit of structure and function in organisms, and all cells come from pre-existing cells through cell division.
What states living things are made of cells?

How many cells are in nucleus?
None! A nucleus is in a cell there are no cells in a cell

What do prokaryotic cells and eukaryotic cell have to do with the cell theory?
they both are cells... and only one has a nucleus..and one the eukaryotic cell the one that has a nucleus, evolves from the prokaryotic cell.... because the prokaryotic cell enters into the DNA casing of the early cell then more come making the eukaryotic cell.

The cell theory states that all cells come from pre-existing cells. This means that new cells are produced through the division of existing cells.
What does The Cell Theory State?
The cell theory is a fundamental concept of Biology that states that all living things are composed of cells; that cells are the basic units of structure and function in living things; and that new cells are produced from existing cells.
