C

Analysis of test questions: fungi belong to eukaryotes, with forming nuclei, bacteria belong to prokaryotes, and there is no forming nuclei in cells; The breathing modes of bacteria and fungi are anaerobic and aerobic; Autotrophic, photoautotrophic and chemoautotrophic. Chemical energy autotrophy does not depend on light energy, but on the energy generated by chemical oxidation for its own synthesis of organic matter. Photoautotrophy is not entirely carried out by chloroplasts and chlorophyll. Photosynthetic bacteria, such as purple sulfur bacteria, green sulfur bacteria and halobacteria, are all photoautotrophic, but they can't directly synthesize organic matter from inorganic substances without using chlorophyll. Therefore, options a, b and d do not meet the meaning of the question.
