The question asks for the general characteristics of animals belonging to the kingdom Animalia. To answer this, we need to recall the fundamental distinguishing features of animals as classified in biology.
Based on these characteristics, we can evaluate the given options.
A) A eukaryotic, multicellular, heterotrophic body organisation, typically lacking a cell wall around their cells
This option accurately describes all the fundamental characteristics of animals: they are eukaryotic, multicellular, heterotrophic, and their cells do not have a cell wall. This is the most comprehensive and correct description.
The question asks to identify which of the given organisms belongs to the Kingdom Protista. To answer this, we need to recall the characteristics of organisms typically classified under Protista and distinguish them from organisms belonging to other kingdoms like Monera, Fungi, and Plantae.
Correct Option: B) Amoeba is a unicellular eukaryotic organism that moves using pseudopods and is a classic example of a protozoan, which belongs to the Kingdom Protista.
The question asks to identify which group of organisms is classified under Kingdom Monera. This requires knowledge of the five-kingdom classification system (Monera, Protista, Fungi, Plantae, Animalia) and the characteristics of organisms belonging to each kingdom.
Correct Option: D) Cyanobacteria (blue-green algae) are prokaryotic organisms and are therefore classified under Kingdom Monera.
The question asks about the major subdivisions of Kingdom Monera. To answer this, we need to recall the classification of organisms, specifically the five-kingdom classification system proposed by R.H. Whittaker, which includes Monera, Protista, Fungi, Plantae, and Animalia. Kingdom Monera comprises all prokaryotic organisms.
Correct Option: B) Archaebacteria and Eubacteria. Kingdom Monera is indeed subdivided into Archaebacteria (ancient bacteria) and Eubacteria (true bacteria). These two groups represent the two major lineages of prokaryotic life, differing significantly in their cell wall composition, membrane lipids, ribosomal RNA sequences, and metabolic pathways.
The question asks to classify Mycoplasmas based on their characteristics: smallest known living cells, independent existence, and complete lack of a cell wall. This requires knowledge of the five-kingdom classification system and the key features of each kingdom.
Correct Option: B) Mycoplasmas are prokaryotic organisms, meaning they lack a true nucleus and other membrane-bound organelles. They are considered the smallest known living cells and are unique among prokaryotes for completely lacking a cell wall. These characteristics align with the definition of organisms belonging to the Kingdom Monera, which includes all bacteria and other prokaryotes.
The question asks to classify slime moulds based on their characteristics (creeping over decaying leaves, engulfing organic matter, producing spore-bearing fruiting bodies) within the five-kingdom system. Understanding the key features of each kingdom is crucial for correct classification.
Correct Option: D) Protista. Slime moulds are classified under Kingdom Protista. They are eukaryotic organisms that exhibit characteristics of both animals (amoeboid movement, phagotrophic nutrition) and fungi (spore formation). They are distinct from true fungi because they engulf their food rather than absorbing it.
