Answered by GPT-5 mini AI
The three main ideas of the cell theory are:

1. All organisms are made of one or more cells (cells are the building blocks of life).
2. The cell is the basic unit of structure and organization in organisms (cells are the smallest units that carry out life’s processes).
3. All cells arise from pre-existing cells (cells do not spontaneously appear).

(These ideas were formulated in the 19th century by scientists such as Schleiden, Schwann and Virchow.)
