to consider something alive (at least what i was taught) the organism has to replicate in the order DNA to RNA to Protein, cells are the smallest units that have this ability.
virus have a different cycle typiclly going: modified RNA to DNA to RNA to Protein which is why they arent considered (yet) to being alive
The German biologist Theodor Schwann concluded that all animals are made up of cells, which contributed to the development of the cell theory. He also proposed that cells are the basic unit of structure and function in living organisms.
His conclusion was that all animals have cells.
The German scientist Theodor Schwann concluded that all animals are composed of cells, and that cells are the basic building blocks of living organisms. This idea laid the foundation for the cell theory, which states that all living things are composed of cells.
Schwann cells and oligodendrocytes
Theodor Schwann was a German physiologist who co-founded the cell theory. He discovered that all animals are made up of cells, which led to the understanding that cells are the basic unit of life. Schwann also identified the role of enzymes in digestion.
Cell Theory..
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.

that all animals were made of cells
The German biologist Theodor Schwann concluded that all animals are made up of cells, which contributed to the development of the cell theory. He also proposed that cells are the basic unit of structure and function in living organisms.
All living things are made of one or more cells.
Schleiden and Schwann came up with what is known as "The Theory of Cells" or "Cell Theory." The main principles of "Cell Theory" are:All cells come from cellsA cell is the basic unit of lifeAll organisms are made of cells
Matthias Schleiden was a German botanist who, along with Theodor Schwann, formulated the cell theory. Schleiden proposed that all plants are composed of cells, which laid the foundation for the study of cells as the basic unit of life.

Cells are the basic unit structure and function of all living thing's+
Matthias Schleiden, a German botanist, is credited with formulating one of the core principles of cell theory—the idea that all plants are composed of cells. Alongside Theodor Schwann, who extended this principle to include animals, Schleiden's work laid the foundation for the modern understanding of cells as the basic unit of life.
