Cell biology – A branch of biology that includes study of cells regarding their physiological properties, structure, and function; the organelles they contain; interactions with their environment; and their life cycle, division, and death.
Biology is the scientific study of life. [1] [2] [3] It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. [1] [2] [3] For instance, all organisms are composed of at least one cell that processes hereditary information encoded in genes, which

Many insects including hoverflies (C, D, E) and the wasp beetle (F) are Batesian mimics of stinging wasps (A, B), which are Müllerian mimics of each other.. In evolutionary biology, mimicry is an evolved resemblance between an organism and another object, often an organism of another species.
[1] In many marine gastropods where the siphon is particularly long, the structure of the shell has been modified in order to house and protect the soft tissue of the siphon. This shell modification is known as the siphonal canal. For a gastropod whose shell has an exceptionally long siphonal canal, see Venus comb murex.
Other terms in biology refer similarly to various taxa; for example: Fungi are described by their growth patterns: molds, yeasts, mushrooms and dimorphic fungi. Lichens structure is described their growth form: foliose, crustose, fruticose or gelatinous. Bryophytes structure is described as foliose or thallose.
