Get Section 1 Cell Theory Study Guide A

The cell theory is one of the fundamental principles of biology. The original version of the cell theory states: • Cells are the basic unit of life. All living organisms, both unicellular and multicellular, are composed of cells. Cells arise from pre-existing cells.

The cell theory has three parts: All living things are made up of cells. Cells are the basic units of structure and function in living things. All cells come from other cells.

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.

Cell theory states that all living organisms are made of the cell which is either unicellular or multicellular. Cell serves as the functional unit of life as it involves in the formation of new cell and other cellular components that are essential for life processes.

The cell theory states that: All living things are composed of one or more cells and cell products. All living cells come from other living cells by the process of cell division. Cells are the basic units of structure and function on organism.

The cell theory includes the following components: all living things are composed of cells, cells are the smallest unit (structure) of living things that can perform the processes (functions) necessary for life, living cells come only from other living cells.

UNDERSTANDING BY DESIGN In this unit on cell theory and cell structure and functions, 7th grade students will be able to recognize the different levels of organization in plants and animals including cells, tissues, organs, organ systems, and organisms (7.12C).

Credit for developing cell theory is usually given to three scientists: Theodor Schwann, Matthias Jakob Schleiden, and Rudolf Virchow. In 1839, Schwann and Schleiden suggested that cells were the basic unit of life. Their theory accepted the first two tenets of modern cell theory (see next section, below).

The three parts of the cell theory are: All living things are composed of cells. Cells are the basic units of structure and function for living things. All cells come from pre-existing cells. Also, organisms grow by “adding on more cells” NOT by increasing the size of their cells.

The cell theory was proposed by two scientists- Schleiden (1838)and Schwann (1839). It says that all the plants and animals are composed of cells and the cell is the basic unit of life. The cell theory was further expanded by Virchow (1855) by suggesting that all cells arise from pre-existing cells.
