Question

prior to cell theory and germ theory, in the 1600s - 1800s, some scientists supported the theory of spontaneous generation. the theory proposed that living (cellular) organisms could form from inanimate objects or from other unrelated organisms. for example, it was thought that cheese or grain could facilitate the formation of mice. which of the following principles of cell theory refute, or contradict, the theory of spontaneous generation? correct answer(s) cells arise from preexisting cells. the cell is the basic unit of life. all living cells came from another living cell. all living things are composed of cells. incorrect answer(s)

Explanation:

The theory of spontaneous generation proposed life could arise from non - living or unrelated sources. Cell theory principles such as cells arising from preexisting cells, all living cells coming from another living cell, and all living things being composed of cells oppose this. The idea that cells have a specific origin in preexisting cells contradicts the random formation of life from inanimate objects proposed by spontaneous generation. The cell being the basic unit of life also implies an organized origin of life rather than spontaneous formation.

Answer:

Cells arise from preexisting cells., All living cells came from another living cell., All living things are composed of cells., The cell is the basic unit of life.
