The third tenet is that (currently at least) living cells only come from other living cells.
The three general tenets are:
1) All organisms are composed of one or more cells.
2) The cell is the structural unit of life.
3) Cells can arise only by division from a preexisting cell.
Theodor Schwann, Matthias Jakob Schleiden, and Rudolf Virchow, invented the cell theory.
By 1855 he already had the idea that 'cells originate from pre-existing cells'.

Atoms cannot be divided into smaller particles.
Rudolf Virchow is responsible for the third tenet of the cell theory, which is that all cells come from other pre-existing cells. In other words, they do not occur through spontaneous generation, also called abiogenesis.

Yes - here we are. A tenet is one of the principles on which a belief or theory is based.

The concept of cells giving rise to other cells as the foundation of cell theory wasn't fully accepted until the 19th century due to challenges in observing cell division process directly, limitations in technology, and resistance to new ideas. It took time for advancements in microscopy and experimental evidence to confirm the process of cell division and establish it as a core tenet of cell theory.

The name of the theory that Schleiden and Schwann developed is the cell theory.

this, basic goodness, is a foundational tenet of the shambhala sect of tibet buddhism.
Nice try bro...read the assigned book. I will see you in class
Microscopes led to the discovery that all organisms are composed of cells. This fundamental tenet of biology, known as the cell theory, states that cells are the basic unit of structure and function in living organisms.
