... that a frond of the seaweed Halimeda tuna(pictured) consists of a single cell? Source: "Typically, the Bryopsidales are filamentous and consist of a mass of continuous cytoplasm held inside a hollow, cylindrical cell wall. There are usually no cross-walls and therefore no physical separation between nuclei or other internal structures. In some genera, such as Halimeda, the filaments are highly branched and packed into a dense mass called a thallus."
ALT1:... that when the seaweed Halimeda tuna(pictured) dies, it breaks down to form "sand"? Source: "During the 1950s when large numbers of deep boreholes were drilled into Pacific atolls, geologists found that the dominant element of the carbonate structure of these atolls was not stony coral but rather a lithified sand made up of the lobes of Halimeda. The members of this genus rank as one of the most important calcifiers of the biosphere; it is likely that their CaCO3 production over all tropical seas is considerably greater than that of the stony corals."
Overall: I really like Alt0, but I'm not seeing in the referenced text where it makes the cited claim. Can you pull the quote? Enwebb (talk) 17:31, 18 June 2019 (UTC)
@Enwebb: Thank you for the review. I have now added the quote above and expanded on the single cell bit in the article. Cwmhiraeth (talk) 18:03, 18 June 2019 (UTC)
Cwmhiraeth thanks! Looks good to me now. Enwebb (talk) 02:18, 19 June 2019 (UTC)
