Here, we summarize a biological scale to give you a sense of the sizes of different biological objects. Knowing the exact dimension of the specimen is critical for a biologist. Here is the list of units that describe the size (in length) of biological objects. To express numbers that are too large or too small to be conveniently written in decimal form, it is common to use “Scientific notation” in biology and other science branches. The biology scale can span a huge range: from an atom to an elephant. Others (such as Rotifer and Tardigrade), however, contain thousands of cells and belong to multicellular animals.īefore we start hunting for microorganisms, we should have a good idea of how small they are and the relative biology scale. Some microorganisms (such as Euglena, Paramecium, and Amoeba) contain only one gigantic cell (called unicellular or single-cellular) and are classified as protists. Many pond creatures fall in the size range between 100-500 micrometers (μm). We will also include these multicellular organisms in this guide. Sometimes, you will find microscopic animals and plants that consist of hundreds or even thousands of cells. They could be free-living single cells or microorganisms that cluster together in large numbers (colonies). Typically, pond water contains a variety of microorganisms. Molds – “fungus-like”, like water mold and slime mold.Protophyta – “plant-like”, like Diatom, green, red, and brown algae.Protozoa – “animal-like”, like Paramecium and Amoeba.Within the umbrella of Protist, the members can be further divided into: They are largely composed of the members of the Archaea and Bacteria kingdoms (both are prokaryotic cells) and unicellular Protists (belong to eukaryotes). ![]() As such, they are only visible under a microscope. They can be unicellular or cell clusters. ![]() Microorganisms or microbes are microscopic organisms that can be found all around the world.
