Reproduction occurs when adults produce sperm and eggs that fuse to form offspring. Each adult Caulerpa, however, consists of just a single cell. Which of the following statements is true? A) Caulerpa violate the pattern component of the cell theory—that all organisms consist of cells. B) Caulerpa violate the process component of the cell theory—that all cells come from preexisting cells. C) Caulerpa violate both the pattern and process components of the cell theory. D) The existence of Caulerpa is consistent with the cell theory. Answer: D Reference: Section 1.1 Bloom's Level: Comprehension LOs: Chp1-2.
