Question

Which theory states that all organisms are made up of cells that are capable of self-reproduction and come only from preexisting living cells? a) Atomic theory. b) Cell theory. c) Abiogenesis theory. d) Germ theory

Answer 1

Answer: b) Cell theory.

Step-by-step explanation:

Cell theory is a scientific theory that states that all living organisms are composed of cells, and that cells are the basic unit of life. The theory was first proposed by Matthias Jakob Schleiden and Theodor Schwann in the mid-19th century and has since been widely accepted as a fundamental principle of biology. The theory states that cells can only arise from preexisting cells and that cells are capable of self-reproduction, which is essential for the continuation of life. The theory also states that all cells perform similar basic functions and contain similar structures, such as a cell membrane, cytoplasm, and genetic material. The cell theory forms the basis for understanding the structure and function of cells and has provided a foundation for the development of many other biological theories.
