Colony
(Science: biology) a group of identical cells (clones) derived from a single parent cell.
(Science: cell culture) a clone of bacterial cells on a solid medium that is visible to the naked eye.
colonial -- Condition in which many unicellular organisms live together in a somewhat coordinated group. Unlike true multicellular organisms, the individual cells retain their separate identities, and usually, their own membranes and cell walls.
Colon Cancer
Colon cancer:
begins with the development of polyps in the epithelium of the colon. Polyps are benign growths
As time passes, the polyps may get bigger.
At some point, nests of malignant cells may appear within the polyps ...
Colony Screen. Bacterial colonies are grown on a nylon filter placed on nutrient agar.
Colony
A visible group of cells arising from a single cell plated on solid medium.
Colony blots
See Colony hybridization.
colonial 1. Level of organization intermediate between unicellular and multicellular - organisms are composed of multiple cells but fail to exhibit specialization of those cells. Examples: Volvox, a colonial alga.
colony - a distinct localized population within a species; includes ants, termites and bees as well as some tent caterpillars, webworms, etc.
comatose - an unconscious state; may be due to disease, injury, or poison ...
Colony Forming Unit (CFU)‚ a bacterium or small number of bacteria which grow into one observable colony on a nutrient medium

colon
A part of the large intestine in mammals which functions in the reabsorption of water from feces.
columella
The sterile central column in the sporangia of mosses and liverworts.
colony
A group of organisms of the same species living together in close association.

1 Coloniality in Chlorella vulgaris
Boraas (1983) reported the induction of multicellularity in a strain of Chlorella pyrenoidosa (since reclassified as C. vulgaris) by predation.
Colony filters are plated at a density of 6 x 6 x 384, or 13,824 colonies per 8 x 12 cm filter. All colonies are plated in duplicate in a unique offset pattern optimized to prevent ambiguity in identification of positive offsets.
Colonial - small, regular groups of motile cells
Capsoid - individual non-motile cells embedded in mucilage
Coccoid - individual non-motile cells with cell walls
Palmelloid - non-motile cells embedded in mucilage ...
colonizer An organism that initiates the biological "conquest" of soil or rock; see also pioneer organism.
colony A cluster of genetically identical individuals formed asexually from a single colonizing individual.
A Volvox colony is an example of a colonial algae. Each Volvox is a hollow sphere with thousands of cells arranged in a single layer on its perimeter. Individual Volvox cells resemble a Chlamydomonas cell.
Weedy habit refers to the propensity of certain species to disperse easily and widely and to colonize disturbed habitats. Xerophyte: a plant well adapted to withstand prolonged drought.
Colony liftBlot taken from colonies (normally bacterial) growing on an agar plate. Normally used for detection of a colony containing a plasmid with a specific inserted sequence (screening).
[They] start off with a bunch of micro colonies on the surface. One here and one some distance away, and they grow up in either mushrooms or towers and some more come up. They leave a space in between themselves.
Screening by hybridization involves spreading the mixture of bacteria out on a dozen or so agar plates to grow several ten thousand isolated colonies.
coli, given a suitable environment for growth, divide and form a colony of hundreds of bacteria in just a few hours. Or visit the CELLS alive! BioCam to see bacteria colony in "real time". A longer, larger, silent version of growing E.
Algae: A heterogeneous group of aquatic, unicellular, colonial or multicellular, eukaryotic and photosynthetic organisms. They belong to the Kingdom Protista and include the multicellular red (rhodophyte), green and brown (kelp) algae.
Suppose that a pet store owner observes that the mice in her colony grow slowly. She hypothesizes that they grow slowly because she does not give them enough food. To test this hypothesis, she uses two groups of mice.
They can be solitary or colonial. A protozoan like an amoeba might spend its whole life alone, cruising through the water. Others, like fungi, work together in colonies to help each other survive.
gonidia - reproductive cells of colonial photosynthetic eukaryotes such as Volvox.
granular/granule cell - most abundant neuron type in the cerebellar cortex of the vertebrate brain.
Polyp. An individual of a solitary coelenterate or one member of a coelenterate colony
Polyphyletic. Refers to a group of species that do not have one common ancestor species
Population density. Number of individuals per unit area or volume ...
The founder effect is the reduction in genetic variation that results when a small subset of a large population is used to establish a new colony.
Founder principle: A small colonizing population is genetically unrepresentative of the source of population.
A mutation of yeast that produces small ( petite"
petite) anaerobic-like colonies.

Inoculative release: The release of relatively small numbers of natural enemies that are expected to colonize, reproduce, and spread naturally throughout an area.
Clone: A group of genetically identical cells or o rganisms that are descended from one parent. Identical twins are clones, as are colonies of bacteria that reproduce by simple cell division.
filter A membrane containing DNA bound to the surface. Filters in TAIR are generally from BAC, YAC, or plasmid colony libraries.
a chronic disease of cattle, sheep and goats, caused by infection by Mycobacterium paratuberculosis (M. Johnei) which causes a chronic enteritis affecting the small intestine, caecum and colon; the main symptoms are diarrhoea and emaciation ...
Hereditary nonpolyposis colorectal cancer (HPCC) A common form of hereditary colon cancer due to defective correction of DNA mismatches. Also called Lynch syndrome.
Then cells were removed, washed, and transferred to minimal media containing lactose as the only sugar source. A few cells were able to grow on minimal media with lactose, and formed colonies. How did these few cells become trp lac Z met bio?
