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.
done

Explanation:

1. Recall the original cell theory (cells are basic unit of life, all living things have cells, cells come from pre - existing cells) and modern cell theory additions.

• For "All cells are similar in structure and function": Modern cell theory explains that while all cells have basic structures (like cell membrane, genetic material), different cells (e.g., prokaryotic vs eukaryotic, muscle vs nerve cells) have structural and functional differences, but the idea of a basic level of similarity in fundamental structures/functions is a modern addition.
• For "Cell contains hereditary information that is passed from cell to cell during cell division": The original cell theory didn't address hereditary information transfer. Modern cell theory includes that DNA is passed during cell division.
• For "Living cells can be created from dead cells": This goes against the cell theory (cells come from pre - existing cells), so it's incorrect.
• For "All cells perform similar metabolic activities": All cells need energy, perform processes like respiration (or similar in prokaryotes), and have basic metabolic pathways, which is a modern understanding.

Answer:

• All cells are similar in structure and function.
• Cell contains hereditary information that is passed from cell to cell during cell division.
• All cells perform similar metabolic activities.
