📌 Organisms may be unicellular, consisting of a single cell, or multicellular, consisting of many cells.
📌 New cells form only through the division of pre-existing cells.
All living things are made of cells.
The foundation of Cell Theory consists of:
The three C principles: Cells compose life, Cells carry out life, Cells come from Cells
1. What is the primary function of the cell membrane?
2. Which statement expresses a central principle of cell theory?
3. A cell is growing and preparing to reproduce; which structure coordinates these activities?
