Anton van Leeuwenhoek made an important contribution to the development of the cell theory. How? a. He articulated the pattern component of the theory-that all organisms are made of cells. b. He articulated the process component of the theory-that all cells come from preexisting cells. c. He invented the first microscope and saw the first cell. d. He invented more powerful microscopes and was the first to describe the diversity of cells.

Antonie Van Leeuwenhoek is considered to be the first microbiologist. His work was completed before Pasteur's. He was the first to use microscopes to observe and describe single-celled organisms, which he originally referred to as animalcules, and which we now refer to as microorganisms. A. How did Van Leeuwenhoek's work provide the basis for Pasteur's work on disproving the theory of spontaneous generation? B. Explain how the results of Pasteur's S-shaped tube experiment were important in disproving spontaneous generation and how it supported the idea that cells come from preexisting cells. (4 points)
Punit I.
You are looking at a sample under a light microscope and observe a new type of cell. You come to the conclusion that it is a bacterium and not a eukaryotic cell. What would you observe to come to this conclusion? a. the cell has a cell wall b. the cell has a flagellum c. the cell does not have a nucleus
