Question

The original cell theory has been expanded upon since it was first developed to include further additions due to advances in research on the cell. Which statements were not in the original cell theory, but are further explained by the modern cell theory? Check all that apply. All cells are similar in structure and function. Cell contains hereditary information that is passed from cell to cell during cell division. Living cells can be created from dead cells. All cells perform similar metabolic activities.

Answer 1

The statements that were not in the original cell theory but are further explained by the modern cell theory include:

1. All cells are similar in structure and function. (This aspect emphasizes the idea of commonality among cells across different organisms, which extends the original theory.)

2. Cell contains hereditary information that is passed from cell to cell during cell division. (This was a later addition reflecting our understanding of DNA and genetics.)

3. All cells perform similar metabolic activities. (Modern cell theory encompasses the idea that all cells have similar biochemical functions, though they may vary in specific activities.)

The statement "Living cells can be created from dead cells." is not accurate and does not align with modern understanding—cells arise from pre-existing cells, not from dead cells.
