Contributions from phycologists, protozoologists, mycologists and other biologists are drawn together in this book to review the current status of the chromophyta (algae containing chlorophylls "A" and "C"). Particular attention is given to the ultrastructure, biochemistry, physiology, systematics and phylogeny of this group of organisms. The text should be of particular interest to phycologists, protozoologists, cell biologists, biochemists, systematists, microbiologists and mycologists.
