Question

In Whittaker classification, non-nucleated unicellular organisms prokaryotes are included under
A. Plantae
B. Monera
C. Protista
D. Animalia

Answer 1

Hint: R.H Whittaker introduced the five Kingdom classification in 1969. Unicellular prokaryotic organisms that existed in the Monera kingdom and contained the Cyanobacteria and bacteria like species. And Animalia, kingdoms, fungi, plantae are found in the eukaryotic organisms expected from the Monera kingdom.

Complete answer:
Monera is the most abundant and oldest organism that present in the prokaryotic unicellular and undergoes the asexual reproduction. Prokaryotic is the single cell organisms and Monera present as a subkingdom in the archaebacterial that can live in the most extreme environment conditions. On the other side eubacteria that is known as a true bacteria and classification not based upon the bacillus, spirillum, and coccus but according to the composition of the chemical cell walls that react with the gram strains.
Mostly bacteria is found in every habitat and have a cell wall, surrounded by the cell membrane but absence of the membrane bound organelles such as chloroplasts, golgi apparatus, ER and Mitochondria. Slime is known as the name of a capsule in which some bacteria are covered. On the basis of nutrition some bacteria are autotrophs and some are kind of heterotrophs.

Therefore the correct option is (B).

Note: Monera kingdom belongs to the unicellular prokaryotic organisms and has no true nucleus. The mode of reproduction, nutrition and phylogenetic relationships are classified by five Kingdom and reproduced both sexually and asexually reproduction. Prokaryotic is a single circular chromosome that is attached with the plasma membrane and reproduces new organisms after the splitting of the two cells.
