Unformatted text preview: low describes evidence that supports the theory that mitochondria and chloroplasts were originally bacteria, EXCEPT: A. DNA is present in both organelles. B. Ribosomes are present in these organelles, and resemble ribosomes of bacteria rather than ones found in the eukaryotic cytosol/endoplasmic reticulum. C. These organelles are similar to bacteria in terms of size and morphology. D. When removed from a eukaryotic cell, such organelles can survive and reproduce on their own. E. Electron transport occurs in membranes of the organelles similar to electron transport on bacterial plasma membranes. 24. Cytoskeletal elements must associate with motor proteins to A. B. C. D. E. move organelles/vesicles inside the cell. help the cell move (itself, or liquid outside the cell). provide a protective/supportive surface outside the plasma membrane. carry out all of the roles in A through C. carry out only two (2) of the roles in A through C. 25. As a spherical prokaryotic cell becomes larger, what issue(s) does it face? A. B. C. D. Increased speed of molecules moving across the inside of the cell. The ratio of plasma membrane area to cytosolic volume increases. The ratio of cytosolic volume to plasma membrane area increases. Increased ability to carry out electron transport reactions.
