The cell is the basic structural and functional unit of all forms of life. ... each controlling a cell's structure by directing, bundling, and aligning filaments. [2]
Both simple and complex cells are linear operators and are seen as filters because they respond selectively to a large number of patterns. However, it has been claimed that the Gabor model does not conform to the anatomical structure of the visual system as it short-cuts the LGN and uses the 2D image as it is projected on the retina .
In biology, cell theory is a scientific theory first formulated in the mid-nineteenth century, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. Cells are the basic unit of structure in all living organisms and also the basic unit ...
Cell biology (also cellular biology or cytology) is a branch of biology that studies the structure, function, and behavior of cells. [1] [2] All living organisms are made of cells. A cell is the basic unit of life that is responsible for the living and functioning of organisms. [3] Cell biology is the study of the structural and functional ...
Light micrograph of a moss's leaf cells at 400X magnification. The following outline is provided as an overview of and topical guide to cell biology: . 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.
Cell structure of a gram positive bacterium. In comparison to eukaryotes, the intracellular features of the bacterial cell are extremely simple. Bacteria do not contain organelles in the same sense as eukaryotes.
Surrounds the cell's cytoplasm, regulates flow of substances in and out. Cell wall (except in Mollicutes, Thermoplasma) Outer covering that protects the cell and gives it shape. Cytoplasm: A watery gel that contains enzymes, salts, and organic molecules. Ribosome: Structure that produces proteins as specified by DNA. Nucleoid
In cell biology, an organelle is a specialized subunit, usually within a cell, that has a specific function.The name organelle comes from the idea that these structures are parts of cells, as organs are to the body, hence organelle, the suffix -elle being a diminutive.
