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,...
Some groups consist of single-celled organisms that have a single nucleus per cell. (A nucleus is a membrane-enclosed structure within a cell that contains the cell's genetic material and controls its growth and reproduction.) Other groups consist of single-celled organisms in which each cell ...
asunicellularormulticellular.Unicellular organisms are those that have only one cell, i.e. single-celled. Examples are prokaryotes and protists. Multicellular organisms are those possessing more than one cell. Examples are plants and animals. The cells of a multicellular organism may share common ...
What is a single-celled organism that carries out all the functions of life by itself? What are the characteristics of living things? What are the six characteristics of living things? You are a living organism. Which characteristics of life do you exhibit? What animal is an example of a ...
The answer to that question is that they can be both. Some protists, like diatoms and amoeba, are unicellular. Other protists, like kelp and slime molds, are multicellular. One might also wonder why are protists eukaryotic if so many of them are single celled, just like bacteria? The an...
Plants produce the gaseous metabolic waste of oxygen through photosynthesis and liquid water through respiration, which are both excreted through stomata pores. Single-celled organisms and body cells use a process called exocytosis, where they collect wastes and toxins in vesicles, which then merge ...
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 a cell wall (think of the cell wall as a tiny plastic bag) filled with various proteins, enzymes and othe...
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...
Plants and single-celled creatures are examples of autotrophs. Photosynthesis is used by nearly all autotrophs to produce glucose – their source of nourishment – from sunlight, carbon dioxide, and water. What is the difference between the food chain and the food web? A food chain shows ...
