Abstract: 7 tab. ["The algal region [of the thallus] has a greater respiration rate and nitrogen content than the medulla, and it absorbs more glucose, asparagine, phosphate, and ammonia than the medulla... The medulla has a greater water content than the algal region, and may function as a water reservoir."]
