EVERYDAY SCIENCE

Detailed explanation-1: -An organism is an individual living thing. It is easy to recognize a living thing, but not so easy to define it. Animals and plants are organisms, obviously. Organisms are a biotic, or living, part of the environment.

Detailed explanation-2: -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-3: -For this reason, living things are called organisms. The activities of the cells are controlled by the cell’s genetic material-its DNA. In some types of organisms, called eukaryotes, the DNA is contained within a membrane-bound structure called the nucleus.

Detailed explanation-4: -Unicellular organisms, such as amoeba, paramoecium, yeast, etc., consist of a single cell. All the vital processes such as nutrition, digestion, excretion, reproduction, etc., are carried out by the single cell.

Detailed explanation-5: -They are neither plants nor animals, yet they are some of the most important life forms on Earth. Explore the world of single-celled organisms-what they eat, how they move, what they have in common, and what distinguishes them from one another-in this video.
