does the cell theory state that cell come from cells that already exist?

and the cell is the most basic unit of life
Yes, according to the cell theory, cells arise from pre-existing cells. This principle is one of the fundamental tenets of modern biology, and it was first proposed by the German scientists Matthias Schleiden and Theodor Schwann in the mid-19th century. The cell theory has three main components:
1. All living organisms are composed of one or more cells.
2. The cell is the basic unit of structure, function, and organization in all living organisms.
3. Cells arise only from pre-existing cells through cell division.
To understand how the cell theory was developed, you can explore the historical experiments and observations that led to its formulation. This includes studies by scientists such as Robert Hooke, who first observed and coined the term "cells," as well as the work of Anton van Leeuwenhoek, who made advancements in microscopy and observed different types of cells. Additionally, studying the experiments of Louis Pasteur on spontaneous generation can provide insights into disproving the idea of cells emerging spontaneously. By examining these findings, you can better grasp the evidence that supports the notion that cells come from pre-existing cells.
