Cell Theory

The basic tenants of cell theory are that all living things are made up of cells and that cells are the basic units of life.

However, cell theory dives deeper than that. Cell theory has evolved over time and is subject to interpretation. Early cell theory was comprised of four statements.

The next lesson: Binomial Nomenclature, both lessons are included in Practice Tests.

The following transcript is provided for your convenience.

The first being, all organisms are made up of cells and so when I say organisms, I mean all living things, basically everything that lives is made up of cells.

The second part of self-theory was that new cells are formed from preexisting cells. Part three, all cells are similar and finally cells are the most basic units of life. In other words, everything is made up of cells. Cells are the basic building blocks of organisms of life.

Some other concepts related to classic and modern cell theory includes statements such as cells provided the basic units of functionality and structure in living things. Cells are both distinct stand alone units and basic building blocks. Energy flow occurs within cells. Cells contain genetic information in the form of DNA and all cells consist of mostly the same chemicals.
