It appears two of these answer choices are correct. The two options that represent the cell theory include A) most cells arise from existing cells, and C) cells are the most basic unit of structure and function in organisms.
What is the Cell Theory?
The Cell Theory refers to a fundamental principle of biology. This principle states that:
1. Cells are the most basic unit of structure and function in organisms.
2. All living organisms are comprised of one or more cells.
3. All cells arise from existing cells.
Many scientists developed this theory over time; it builds the foundation of most contemporary biology so we can develop a better understanding of organisms and their functions.
