large clusters and having a very short life and are said to pervade each and every part of universe‚ even in tissues of plants and flesh of animals.[21] However‚ the earliest known idea to indicate the possibility of diseases spreading by yet unseen organisms was that of the Roman scholar Marcus Terentius Varro in a 1st-century BC book titled On Agriculture in which he warns against locating a homestead near swamps:… and because there are bred certain minute creatures that cannot be seen by the eyes‚

Diversity in Living Organisms (Science) |Close X | |[pic] Classification And Evolution Classification refers to the identification‚ naming‚ and grouping of organisms into a formal system based on similarities in their internal and external structure or evolutionary history. It determines the methods of organizing diversity of life on earth. Therefore‚ classification helps in understanding millions of life forms in detail. Who started the classification of organisms? Let us explore the history of

Section One : In the discipline known as taxonomy‚ scientists classify organisms and assign each organism a universally accepted name. The first part of the scientific name—in this case‚Ursus—is the genus to which the organism belongs. Agenus(JEE-nus; plural: genera‚ JEN-ur-uh) is a group of closely related species. Linnaeus’s hierarchical system of classification includes seven levels. They are—from smallest to largest—species‚ genus‚ family‚ order‚ class‚ phylum‚ and kingdom

Definition of Microorganism Microorganism (from the Greek: mikrós‚ "small" and organismós‚ "organism") is an organism that is microscopic (usually too small to be seen by the naked human eye). Microorganisms live in all parts of the biosphere where there is liquid water‚ including soil‚ hot springs‚ on the ocean floor‚ high in the atmosphere and deep inside rocks within the Earth’s crust. Microorganisms are critical to nutrient recycling in ecosystems as they act as decomposers

into more than one kingdom? In the early days of biology‚ all organisms were classified as either plants or animals. Single-celled eukaryotic organisms such as algae and Paramecium were assigned to one of the kingdoms according to whether they are photosynthetic or not. Fungi and prokaryotes were grouped with plants‚ because fungi are sedentary and prokaryotes have cell walls. A five-kingdom scheme was devised because some organisms don’t fit well into a two-kingdom system of classification. The

They also differ depending on the function they have in an organism. To make things simpler‚ cells are categorized into two vast groups: Prokaryotic and Eukaryotic Cells. These two types of cells are different from each other while still sharing some similarities. Eukaryotic and Prokaryotic Cells perform the same
