What does Halimeda precipitate?

What does Halimeda precipitate?

Calcification in Halimeda is seen to be a result of the anatomy of the thallus in which the sites of calcification are within a semi-isolated chamber where removal or addition of CO2 due to photosynthesis or respiration can effectively change [COCO2-3] thereby resulting in precipitation of CaCO3.

Is Halimeda unicellular or multicellular?

Some of the Chlorophyta are all one cell, or unicellular, even though they look like a big multicellular plant. Examples of Chlorophyta include Ulva (sea lettuce), Halimeda, and Codium.
