Principles of Biology Chapter 3 Quiz

The cell theory states

• all organisms are composed of only one cell.

• organelles are the basic living unit of structure and function of organisms.

• all cells come only from other cells.

• all organisms are composed of only one cell AND organelles are the basic living unit of structure and function of organisms.

According to cell theory

• all organisms are composed of tissues.

• the smallest unit of life is a nucleus.

• a multicellular organism is composed of many cells.

• new cells arise only from preexisting cells.
