Question

who proposed cell theory?what are the cardinal principles of it? ​

Answer 1

Answer:

By the late 1830s, botanist Matthias Schleiden and zoologist Theodor Schwann were studying tissues andproposed the unified cell theory. The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells

Explanation:

The three principles/tenets of the cell theory are(not in any order):

• Cells are the basic structural unit of life. As you know, cells make up our tissue which makes up our organs that make up our systems and the systems of organs make up an organism like us.
• Organisms are composed of one or more cells. We are composed of trillions of cells while an amoeba is composed of one only single cell.
• All cells come from pre-existing cells. This means that cells can replicate and produce offspring meaning that there must have been a singular cell that gave rise to all life on Earth. Modes of cell replication are Mitosis, Meiosis and Binary Fission(in bacteria).
