Q.1. What is are Lichen Plants?
Ans. Lichens are bizarre organisms and no two are alike. Lichens are a complex life form that is a symbiotic partnership of two separate organisms, a fungus and an alga. The dominant partner is the fungus, which gives the lichen the majority of its characteristics, from its thallus shape to its fruiting bodies.
Q.2. How Litmus is prepared from Lichen Plants?
Ans.Like most paper, litmus paper is made from wood cellulose. The wood is treated with solvents prior to paper manufacturing in order to remove resinous material and lignin from the wood.
The ability of litmus paper to change color when exposed to an acid or base is a result of litmus paper being infused with lichens.
Litmus is a water soluble mixture of different dyes extracted from lichens. ... Lichens are plants which belong to the Thallophyta group. To obtain litmus solution, the crushing and grinding of lichens are done. The dyes are then added to neutral water to get the required litmus solution.
