1.An individual form of life, such as a bacterium, protist, fungus, plant, or animal, composed of a single cell or a complex of cells in which organelles or organs work together to carry out the various processes of life. 2.A system regarded as analogous in its structure or functions ...
organism: An individual form of life, such as a bacterium, protist, fungus, plant, or animal, composed of a single cell or a complex of cells in which organelles or organs work together to carry out the various processes of life.
The unicellular organism is composed of one cell, while multicellular have numerous cells. Unicellular organisms such as bacteria form the simplest form of life, while multicellular organisms such as a cow display complex forms of life. The cells of living organisms are classified as either ...
(1822–1895) was the first to disprove the idea of abiogenesis by showing that each cell results from cell division. Rudolf Virchow (1821–1902) confirmed this, noting that fusion of cellular precursors (germ cells) is the only alternative for generating new cells. Two general types of ...
of the association of multiple cell phenotypes produced from stably differentiated cell types. Individual cardiomyocytes have the ability to contract regularly, but they can only pump fluids when associating with epithelial layers. (Right) Antibiotic resistance is an emergent property of biofilms, where ...

of water and solutes. In dry weather the cortical layers can lose so much water that they shrink and become brittle. Remarkably, cell damage is minimal even though air spaces can occur within fungal cells, and on rewetting the thallus rehydrates and cell structure is regained. There is, ...
