Bacteria
22 linksBacteria (singular bacterium, common noun bacteria) are ubiquitous, mostly free-living organisms often consisting of one biological cell.
Bacteria (singular bacterium, common noun bacteria) are ubiquitous, mostly free-living organisms often consisting of one biological cell.
Like all other organisms, bacteria contain ribosomes for the production of proteins, but the structure of the bacterial ribosome is different from that of eukaryotes and archaea.
Biology
17 linksScientific study of life.
Scientific study of life.
For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations.
DNA
18 linksDeoxyribonucleic acid (DNA) is a polymer composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses.
Life
14 linksQuality that distinguishes matter that has biological processes, such as signaling and self-sustaining processes, from that which does not, and is defined by the capacity for growth, reaction to stimuli, metabolism, energy transformation, and reproduction.
Quality that distinguishes matter that has biological processes, such as signaling and self-sustaining processes, from that which does not, and is defined by the capacity for growth, reaction to stimuli, metabolism, energy transformation, and reproduction.
Organisms, or the individual entities of life, are generally thought to be open systems that maintain homeostasis, are composed of cells, have a life cycle, undergo metabolism, can grow, adapt to their environment, respond to stimuli, reproduce and evolve over multiple generations.
Virus
12 linksA virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism.
Eukaryote
16 linksEukaryotes are organisms whose cells have a nucleus enclosed within a nuclear envelope.
Evolution
12 linksChange in the heritable characteristics of biological populations over successive generations.
Change in the heritable characteristics of biological populations over successive generations.
It is this process of evolution that has given rise to biodiversity at every level of biological organisation, including the levels of species, individual organisms and molecules.
Metabolism
11 linksMetabolism (, from μεταβολή metabolē, "change") is the set of life-sustaining chemical reactions in organisms.
Multicellular organism
8 linksA multicellular organism is an organism that consists of more than one cell, in contrast to a unicellular organism.
Protist
8 linksA protist is any eukaryotic organism (that is, an organism whose cells contain a cell nucleus) that is not an animal, plant, or fungus.
