Explanation:
Carbonic acid is made from dissolving carbon dioxide in water.

A prothallus is a small thin blade of chlorophyllian cells when it is green but can also be colorless and saprotrophic. It is derived from the development of a protonema formed during the germination of a spore in pteridophytes (Pteridophyta, ferns and other closely related species). It is a structure formed by mitotic divisions of haploid cells.
