Answer:
1. Binomial Nomenclature is the biological method of naming the organisms in which the name consists of two words, where the first term refers to the genus and the second term refers to the individual itself.
various conventions followed while writing Binomial nomenclature are :
The first letter of the genus name must be capital and the first letter of the species name must be a small letter.
Scientific names must be underlined separately when written by hand.
2. The advantages of classifying organisms:
It makes us aware of and gives us information regarding the diversity of plants and animals.
It makes the study of different kinds of organisms much easier.
It tells us about the inter-relationship among the various organisms.
It helps to understand the evolution of organisms
3. Both bacteria and amoeba are single celled yet are placed in different kingdoms. ... This is due to the reason that bacteria is prokaryote having cell wall whereas Amoeba is eukaryote and does not possess cell wall. That is why bacteria is placed in monera and. Regards.
4. Whittaker proposed an elaborate five kingdom classification – Monera, Protista, Fungi, Plantae and Animalia. The main criteria of the five kingdom classification were cell structure, body organisation, mode of nutrition and reproduction, and phylogenetic relationships.
5. The major modes of nutrition among protists are autotrophy (involving plastids, photosynthesis, and the organism's manufacture of its own nutrients from the milieu) and heterotrophy (the taking in of nutrients
