Question

rudolf virchows work resulted in the claim that all cells come from preexisting cells. how did this impact the creation of cell theory? it significantly contradicted earlier claims about cells in cell theory. it caused scientists to quit researching cells until new microscopes were invented. it showed that cell theory is very misunderstood in the scientific community. it added to our understanding of cells, completing the claims in cell theory.

Explanation:

Rudolf Virchow's contribution to cell theory was proposing that all cells come from pre - existing cells. This was a key addition to the cell theory. Let's analyze each option:

• Option 1: Saying it contradicted earlier claims is wrong. His work was a crucial addition, not a contradiction. Earlier ideas in cell theory were being built upon, and his idea fit into the developing theory.
• Option 2: There's no indication that his work made scientists stop researching cells. In fact, it likely spurred more research into how cells divide and originate.
• Option 3: His work didn't show that cell theory was misunderstood. Instead, it helped to complete the understanding of cell origin within the cell theory.
• Option 4: His proposal that all cells come from pre - existing cells added to our understanding of cells and completed the claims in cell theory. The cell theory has three main parts, and his work contributed to the part about cell origin.

Answer:

It added to our understanding of cells, completing the claims in cell theory.
