It is difficult to classify viruses as living organisms because they are not made of cells. They only become alive when they find a host i.e. a living cell to live in.ome algae are difficult to classify because they sometimes do not properly fit in one of the kingdoms since they may have characteristics from a few of the kingdoms.
After long debate, lichen are now classified as fungi, under the genus and species of the host fungus. p47â48 This allows specimens to be put into boxes and labelled. By having specific names, researchers know what they are working on: that is one of the basic functions of taxonomy.The system still has its problems.fter long debate, lichen are now classified as fungi, under the genus and species of the host fungus. p47â48 This allows specimens to be put into boxes and labelled.
