Answer:
<em>Many scientists opposed the "cell theory" </em>when it was first introduced because they believed that <u>even "non-living matters" could produce or generate a living tissue.</u> This was called<em> </em><em>"spontaneous generation."</em><em> </em>The appearance of the fly's larva<em> (maggots)</em> on meat supported this belief of theirs.
It was Louis Pasteur who was able to disprove this concept.
Explanation:
The discovery of cell came about when the microscope was invented. It was first discovered by Robert Hooke, an English natural philosopher in the <em>1600s</em>. However, he wasn't really sure about the structure and function of the cell during his time. It was Anton van Leeuwenhoek, a Dutch scientist, who proposed that "<em>motility"</em> is a quality of life.
Developing the cell theory was credited to Theodor Schwann and Matthias Schleiden.
