Detailed explanation-1: -Kayla summarizes the cell theory to her class. She states that all organisms are made up of one or more cells. Which pair of statements correctly completes her summary? The cell is the basic unit of all organisms, and all cells come from existing cells.
Detailed explanation-2: -The CELL THEORY, or cell doctrine, states that all organisms are composed of similar units of organization, called cells. The concept was formally articulated in 1839 by Schleiden & Schwann and has remained as the foundation of modern biology.
Detailed explanation-3: -The cell theory states that all biological organisms are composed of cells; cells are the unit of life and all life come from preexisting life. The cell theory is so established today that it forms one of the unifying principles of biology.
Detailed explanation-4: -The first part states that all organisms are made of cells. The second part states that cells are the basic units of life. These parts were based on a conclusion made by Schwann and Matthias Schleiden in 1838, after comparing their observations of plant and animal cells.
