Match the following. 1. the basic building block of all forms of life resolving power 2. the idea of Schleiden and Schwann that the basic unit of life is the cell and that all living organisms are composed of cells cell 3. theory that states that the basic unit of life is the organism itself, which may be divided into cells for efficiency cell theory 4. the ability to clearly distinguish between two objects organismal theory

The cell is the smallest known unit of all living organisms. They are called the building blocks of life. An organism can be unicellular (made up of one cell) or multi-cellular (made up of many cells).

2. Cell theory was formulated and developed by Schleiden, Schwann, and Virchow. They are considered as the basic principles of biology.

It states:

1. Living organisms are made up of cells.

2. Cells are the basic unit of life.

3. Cells are formed from pre-existing cells.

4. Energy flows inside the cell.

5. DNA is passed on from cell to cell.

6. All cells have the same basic chemical composition.

3. Organismal theory is the intended counter-argument of the cell theory. It was developed by Reichert, Strasberger, Sherrington, and Pavlov. It argues that the basic unit of life is the organism itself, suggesting that an organism came about from a cell that expanded.

4. Resolving power is the ability of an optical instrument like a microscope or a telescope to view objects that are close together as separate, abling the viewer to distinguish the two from each other.
