NEET BIOLOGY

Detailed explanation-1: -A unicellular organism, also known as a single-celled organism, is an organism that consists of a single cell, unlike a multicellular organism that consists of multiple cells. Organisms fall into two general categories: prokaryotic organisms and eukaryotic organisms.

Detailed explanation-2: -Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. Unicellular organisms include bacteria, protists, and yeast.

Detailed explanation-3: -Unicellular organisms are made up of only a single cell. There are millions of kinds, from yeasts to algae and bacteria, but there are also little unicellular animals, such as the ‘slipper animalcule’.

Detailed explanation-4: -Single cell is capable of performing all the life processes like obtaining food, respiration, excretion, growth, and reproduction. One common example of such organism is Amoeba. Multicellular organism are those that consists of multiple cells.

Detailed explanation-5: -Bacteria, amoeba, Paramecium, archaea, protozoa, unicellular algae, and unicellular fungi are examples of unicellular organisms. These unicellular organisms are mostly invisible to the naked eye, hence, they are also referred to as microscopic organisms. Most of the unicellular organisms are also prokaryotes.
