🧬 CELLS, CELL THEORY, ORGANELLES & MICROSCOPES STUDY GUIDE

What is a cell?

The basic structural and functional unit of all known organisms. It is the smallest unit of life that can replicate independently.

What are the three main components of the Cell Theory?

1. All known living things are made up of one or more cells.2. The cell is the basic unit of structure and function in all living organisms.3. All cells arise from pre-existing cells by division.
