Question

scientists continue to explore the boundaries of cell theory, especially with discoveries like viruses and synthetic cells. which of the following scenarios would most likely challenge or expand the current understanding of cell theory? a. a fossilized organism is found that shows evidence of multicellularity from over 2 billion years ago b. a new microscope allows scientists to observe organelles in greater detail than ever before c. a newly discovered organism is found to be made entirely of a single, large cell that performs all life functions d. a new structure is created in a lab that can reproduce and carry out metabolism but lacks a traditional cell membrane

Explanation:

Cell theory states that all living things are made of cells, cells are the basic unit of life, and all cells come from pre - existing cells. A new structure that can reproduce and carry out metabolism but lacks a traditional cell membrane challenges the idea of what constitutes a cell. Option A just provides historical evidence of multicellularity, option B is about better observation of organelles, and option C is a single - celled organism which is in line with cell theory.

Answer:

D. A new structure is created in a lab that can reproduce and carry out metabolism but lacks a traditional cell membrane
