1. Marchantia bears Antheridia and archegonia on separate thalli

2. Responses of ocean acidification Acclimatised thalli to seawater carbon chemistry and light

3. Thalli are linear and prostrate, with smooth margins and a distinct dorsal sulcus.

4. Bladderwrack is distinguishable by its air-filled “bladders”, or thalli, that keep it afloat

5. An air - filled sac found in large numbers in the thalli of certain seaweeds ( e . g . bladderwrack ).

6. On Sabouraud agar the yellow variant develops markedly yellow thalli, whereas the white variant produces white aerial mycelium.

7. Crustose thalli, which resemble a crust closely attached to a surface, are drought-resistant and well adapted to dry climates

8. The term “Calcareous algae” refers to various kinds of benthic and planktonic algae whose thalli contain biochemically precipitated calcium carbonate (CaCO 3) as skeletal material (Wray, 1977; Braga and Riding, 2005).Precipitation of CaCO 3 (as calcite and/or aragonite) may occur within or on the algal bodies
