Cell (biology) From Wikipedia, the free encyclopedia Jump to: navigation search Drawing of the structure of cork as it appeared under the microscope to Robert Hooke from Micrographia which is the origin of the word " cell " being used to describe the smallest unit of a living organism Cells in culture, stained for keratin (red) and DNA (green) The cell is the functional basic unit of life. It was discovered by Robert Hooke and is the functional unit of all known living organisms . It is the smallest unit of life that is classified as a living thing, and is often called the building block of life. Some organisms, such as most bacteria , are unicellular (consist of a single cell). Other organisms, such as humans , are multicellular . Humans have about 100 trillion or 10 µm nanogram anterior horn in the spinal cord while granule cells in the cerebellum brain stem Pseudounipolar cells The largest known cells are unfertilised ostrich egg cells which weigh 3.3 pounds. In 1835, before the final cell theory was developed, Jan Evangelista Purkyně observed small "granules" while looking at the plant tissue through a microscope. The

Technology Cell biology Sci-Tech Encyclopedia: Cell biology Home Library Science Sci-Tech Encyclopedia The study of the activities, functions, properties, and structures of cells. Cells were discovered in the middle of the seventeenth century after the microscope was invented. In the following two centuries, with steadily improved microscopes, cells were studied in a wide variety of plants, animals, and microorganisms , leading to the discovery of the cell nucleus and several other major cell parts. By the 1830s biologists recognized that all organisms are composed of cells, a realization that is now known as the Cell Doctrine. The Cell Doctrine constitutes the first major tenet upon which the contemporary science of cell biology is founded. By the late 1800s biologists had established that cells do not arise de novo, but come only by cell division, that is, division of a preexisting cell into two daughter cells. This is the second major tenet upon which the modern study of cells is based. See also Microscope By the end of the nineteenth century chromosomes had been discovered, and biologists had described mitosis—the distribution at cell division of chromosomes to daughter cells. Subsequent studies showed that the chromosomes contain genes and that

Cell Biology Biological Cell Introduction - Cell Biology It only takes one biological cell to create an organism. In fact, there are countless species of single celled organisms, and indeed multi-cellular organisms like ourselves. A single cell is able to keep itself functional by owning a series of ' miniature machines ' known as organelles . The following list looks at some of these organelles and other characteristics typical of a fully functioning cell. The italic links for each lead to an extra description in the dictionary, as do all similar links in the tutorials; Mitochondrion An important cell organelle involved in respiration Cytoplasm A fluid surrounding the contents of a cell and forms a vacuole Golgi Apparatus The processing area for the creation of a glycoprotein Endoplasmic Reticulum An important organelle heavily involved in protein synthesis.

Movie Gallery Animal Cell Structure Animal cells are typical of the eukaryotic cell, enclosed by a plasma membrane and containing a membrane-bound nucleus and organelles. Unlike the eukaryotic cells of plants and fungi, animal cells do not have a cell wall. This feature was lost in the distant past by the single-celled organisms that gave rise to the kingdom Animalia . Most cells, both animal and plant, range in size between 1 and 100 micrometers and are thus visible only with the aid of a microscope. The lack of a rigid cell wall allowed animals to develop a greater diversity of cell types, tissues, and organs. Specialized cells that formed nerves and muscles—tissues impossible for plants to evolve—gave these organisms mobility. The ability to move about by the use of specialized muscle tissues is a hallmark of the animal world, though a few animals, primarily sponges, do not possess differentiated tissues. Notably, protozoans locomote, but it is only via nonmuscular means, in effect, using cilia, flagella, and pseudopodia. The animal kingdom is unique among eukaryotic organisms because most animal tissues are bound together in an extracellular matrix by a triple helix of protein known as collagen . Plant and fungal cells are bound together in tissues or aggregations by other molecules, such as

Epithelial cell transcytosis of polymeric IgA by its receptor requires polarized membrane trafficking. Mostov and colleagues now show that a signalling cascade involving the tyrosine kinase YES, EGFR, ERK and the Rab11 effector FIP5 regulates this process. Focus on Autophagy Autophagy targets damaged organelles and proteins for lysosomal degradation. This potent degradation mechanism has crucial roles in development, immune defence, programmed cell death, tumour suppression, neurodegeneration and stress response. The September 2010 issue of Nature Cell Biology presents a series of specially commissioned Reviews, Perspectives and Commentaries highlighting new insights into this process.
