The Prochlorophytes

  • Ralph A. Lewin


Prochlorophytes (Lewin, 1976) are phototrophic prokaryotes that contain chlorophylls a and b and are capable of evolving oxygen when suitably illuminated. Some microbiologists may prefer to regard prochlorophytes and cyanophytes as bacteria (Gibbons and Murray, 1978). However, to avoid the circumlocutions that this would entail I shall here refer to prochlorophytes as algae, using the word “alga” in its loose classical sense, without implications of monophylesis or polyphylesis, prokaryosis or eukaryosis.
