Hint: The organisms can be broadly classified into two groups, namely unicellular organisms and multicellular organisms depending upon the number of cells. Unicellular organisms are made up of only one single cell. Examples include Amoeba, Paramecium, yeast, bacteria. Multicellular organisms are those organisms that are made up of more than one cell. Examples include human beings, animals.
Complete answer:
A multicellular organism is an organism composed of many cells. Some of the characteristics of multicellular organism are discussed below:
- The term “multi” is technically used to refer to something that is more than one, hence “multicellular” means more than one.
- The multicellular organisms are having cellular specialization and division of labour. The cells become dependent on each other and thus works efficiently. The cells working in coordination for the proper functioning of a multicellular organism.
- Multicellular organisms are complex in nature and are made of more than one cell.
- They are eukaryotes, i.e., they contain membrane-bound structures.
- Their size increases with the number of cells in an organism.
- Their cells exhibit division of labour. Thus the proper coordination of cells in multicellular organisms forming their complex nature.
- Examples of multicellular organisms: Fungi, Humans, Plants, and Cows etc.
- Viruses are considered as acellular organisms, while bacteria and all the protozoans are unicellular.
Hence, the correct answer is option (D).
Note: R.H. Whittaker (1969) proposed a Five Kingdom Classification. The kingdoms named by him were named Monera, Protista, Fungi, Plantae and Animalia. The group of organisms falling under Monera and Protista are unicellular while the organisms under Fungi, Plantae and Animalia are multicellular in nature.
