Which experiments led to changes to the original cell theory? experiments that showed that blood cells transport gases waste, and nutrients throughout the body experiments that showed that all cells are similar in how they metabolize and in their composition experiments that transplanted synthetic chromosomes into bacterial cells to create a new species experiments that established the existence of single -celled organisms and microbes

Answer 1

## Step 1The original cell theory, proposed in 1839 by Matthias Schleiden and Theodor Schwann, states that all living organisms are made up of cells, the cell is the basic unit of life, and all cells arise from pre-existing cells. ## Step 2The experiments that led to changes in the original cell theory were those that established the existence of single-celled organisms and microbes. This was a significant discovery as it showed that life could exist in a single cell, not just in multicellular organisms.## Step 3The discovery of single-celled organisms and microbes expanded the understanding of the cell theory by showing that life could exist in a single cell, not just in multicellular organisms. This led to the modification of the original cell theory to include the idea that cells can exist as single-celled organisms.
