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!
Theodor Schwann wrote the first two parts of the cell theory
Two scientists came up with The Cell Theory. It was in 1839, Matthias Schleidan and Theodor Schwann, two German Biologists came up with this theory.
Cell theory cannot be changed to cell law because they are two different concepts. Cell theory is a collection of scientific principles that describe the basic properties of cells, while cell law does not exist as a recognized scientific concept.
Well, it is a critical question, but still the answer exist,, Rudolf Virchow has given the best contribution among the four to the cell theory... He developed the theory given by Theodor schawnn.... and the other two did not contribut much in this.....Have a good day!! :)
The two theories of evolution in a eukaryotic cell are endosymbiotic theory and gene duplication. Endosymbiotic theory suggests that eukaryotic cells evolved from a symbiotic relationship between different prokaryotic organisms. Gene duplication theory suggests that gene duplication events have played a significant role in the evolutionary development of new functions and complexity in eukaryotic cells.

There are two things. The organelle is the chloroplast, but there is also a cell wall.
Schleiden and Schwann
Credit for developing cell theory is usually given to three scientists: Theodor Schwann, Matthias Jakob Schleiden, and Rudolf Virchow. In 1839, Schwann and Schleiden suggested that cells were the basic unit of life. Their theory accepted the first two tenets of modern cell theory. However, the cell theory of Schleiden differed from modern cell theory in that it proposed a method of spontaneous crystallization that he called "free cell formation".
Exceptions are of two types: checked exceptions and unchecked exceptions.

1. Cells are the basic unit of structure in all living things.2. Cells carry on all life processes.even though you only said two...3. Cells are produced by other living cells.
The cell theory was given by three scientists: Matthias Schleiden, Theodor Schwann, and Rudolf Virchow. They proposed that all living organisms are composed of cells, cells are the basic unit of structure and function in living organisms, and new cells arise from pre-existing cells.
the cell theory and the microscope
The two main theories of hematopoiesis are the monophyletic theory, which suggests that all blood cells arise from a common stem cell, and the polyphyletic theory, which proposes that different blood cell lineages have separate origins. Recent evidence supports the monophyletic theory, where a single hematopoietic stem cell gives rise to all blood cell types through a hierarchical differentiation process.
Cell Theory. It states that all new cells are created by old cells dividing into two.
