Cell theory states that all living organisms are composed of cells, but there are notable exceptions. First, viruses, which are not considered living organisms, lack cellular structure and cannot reproduce independently. Second, the first cells, or prokaryotes, are thought to have originated from non-cellular entities, blurring the lines of the theory's definition. Lastly, the existence of multinucleate cells, such as skeletal muscle fibers and certain fungal cells, challenges the idea that a cell should contain a single nucleus.
Viruses
The name of the theory that Schleiden and Schwann developed is the cell theory.
Exception to "every cell came from another cell": The first cell ever. (Controversial) exception to "a cell is the smallest unit of life"/"all life is made of cells": viral matter. Hope this helps!
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.
the scientist who fond the cell theory like Robert hooke
Viruses
Presence of extra-chromosomal DNA: Mitochondria and chloroplasts
It has 3:)
Matthias Scheiden was a German botanist who, along with Theodor Schwann, helped establish the cell theory. Scheiden's contributions include the discovery that plants are composed of cells, laying the foundation for modern cell biology and the cell theory.
* The cell is the basic unit of living things
The name of the theory that Schleiden and Schwann developed is the cell theory.
credit is given mainly to 3 scientists which are: Theodor Schwann, Matthias Jakob Schleiden, and Rudolf Virchow for having created the cell theory

The three assumptions of cell theory are 1: All cells form from other cells 2: A cell is the basic unit of life 3: All organisms are mad up of cells
