An organism would, therefore, be any animal, plant, fungus, protist, bacterium, or archaeon on Earth. These organisms may be classified in various ways. One of the ways is by basing upon the number of cells that make it up. The two major groups are the single-celled (e.g. bacteria,...
of a few kinds of simple single-celled organisms, but slowly plants and animals of increasing complexity evolved. Interrelationships developed so that certain plants grew in association with certain other plants, and animals associated with the plants and with one another to formcommunitiesof organisms...
Definition: an organism with a nucleus and other membrane-bound organelles inside the cell(s) Table of Contents Eukaryote refers to any of the single-celled or multicellular organisms whose cell contains a distinct, membrane-bound nucleus. Organisms such as animals, plants, fungi, and protists ...
A protist is defined as a eukaryotic organism that is a member of the Kingdom Protista. While the protist definition states that they can be unicellular (single-celled) or multicellular, most members of the Kingdom Protista are unicellular and microscopic in size. The other eukaryotic kingdoms ...
Egestionis the act of excreting unusable or undigested material from a cell, as in the case of single-celled organisms, or from thedigestive tractof multicellular animals. As defined above, elimination broadly defines the mechanisms of waste disposal by living systems at all levels of complexity...
What type of organism is archaea? Archaea belong to the domain Archaea and are single-celled, prokaryotic organisms that do not have membrane-bound organelles and are distinct from both bacteria and eukaryotes. How do archaea compare to bacteria? Archaea and bacteria are both prokaryotes and do ...
A bacterium is a small, single-celled organism. In the case of E. coli, the bacteria are about one-hundredth the size of a typical human cell. You can think of the bacteria as acell wall(think of the cell wall as a tiny plastic bag) filled with various proteins, enzymes and other ...
prokaryotic cells are single-celled microorganisms known to be the earliest on earth. prokaryotes include bacteria and archaea. the photosynthetic prokaryotes include cyanobacteria that perform photosynthesis. a prokaryotic cell consists of a single membrane and therefore, all the reactions occur within the...
Exist as either single celled or multicellular organisms Can reproduce sexually or asexually Morphology and Structure of Fungi There are a wide variety that range from the smallest unicellular fungi such as yeast to larger multicellular capable of forming hyphal threads or false roots. For this reaso...
They are the single-celled autotrophic organism which was considered to be the first living organisms on earth. Using solar energy they convert the organic compounds into inorganic compounds. They are capable of making oxygen by using the carbondioxide. ...
