Apr 28, 2017 · There are 3 recognized domains, or broadest classification of organism. These are Bacteria, Archaea, and Eukarya. In the simplest case, an organism can be a bacteria, a DNA molecule containing genetic information wrapped in a protective plasma membrane.

May 28, 2019 · An organism is an individual life form with characteristics that set it apart from rocks, minerals or viruses. An organism by definition must have the capacity to metabolize, grow bigger, react to stimuli, reproduce and maintain homeostasis.

Many criteria, few of them widely accepted, have been proposed to define what an organism is. Among the most common is that an organism has autonomous reproduction, growth, and metabolism. This would exclude viruses, despite the fact that they evolve like organisms.

Aug 18, 2023 · Organism (biology definition): a living thing that has an organized structure, can react to stimuli, reproduce, grow, adapt, and maintain homeostasis. Etymology: the term organism comes from the Greek organon, meaning “instrument”. Synonyms: life form; living being; living thing. Also see: life, prokaryote, eukaryote

Feb 6, 2025 · Living things, or organisms, are entities that exhibit life processes such as growth, reproduction, response to stimuli, and metabolism. They include flora (plants) and fauna (animals), all contributing to the complex web of life within ecosystems.

Jul 4, 2024 · Organisms are the fundamental units of life, diverse in form and function, inhabiting every corner of our planet. From the simplest bacteria to the most complex human, organisms play vital roles in maintaining ecological balance, supporting life …

Mar 29, 2024 · Organisms span a vast spectrum, from unicellular entities like bacteria and archaea to multicellular beings such as animals, plants, and fungi. Regardless of their complexity, all organisms share certain fundamental capabilities: reproduction, growth, maintenance, and responsiveness to environmental stimuli.

All organisms are considered to be the basic aspect of the form of life on the earth. Types of Organisms. On the basis of mode of nutrition, organisms can be differentiated in 2 types. Producers – Producers are the organisms, which are not dependent on others for food. They can produce it in their own body. These organisms are also called ...

All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, adaptation, growth and development, homeostasis, energy processing, and evolution. When viewed together, these characteristics serve to define life.

The organism is a fundamental analytical, methodological, epistemic, and ontological biological category. It is the basic unit of biological classification (the species is a group of similar organisms), of ecology, and of evolution. The organism is therefore a reference point for biological description and explanation.
