A tool used in the identification of unknown plants by stating the conspicuous features by which the various taxa can be recognized. Two contrasting choices are presented at each step. One choice in the couplet is accepted and the other rejected, weaving a path to the indentity of the plant.
a tool used to determine the identity of plants.
a method for determining the identity of something (like the name of a bird, a plant, or a fish) by going through a series of choices that leads the user to the correct name of the item.
a classification that usually has two choices at each step. It is based on an "either... or" classification system, that is, either something has a certain characteristic or it doesn't.
A device for identifying organisms based on the answers to a series of questions, with each question involving alternate choices (Morris 1992).
a biological tool for identifying unknown organisms to some taxonomic level (e
a guide for classification and identification, somewhat like a map through a classification system that was developed previously
a method for determining the identity of sometihing (like a butterfly, a plant, Many cetaceans have dorsal fins
an organized set of couplets of mutually exclusive characteristics of biological organisms
a sequence of steps that allows the identification of a living thing
a series of paired statements
a series of questions which leads to the identification of an item
a tool that allows the user to determine the identity of items and organisms in the natural world
a tool that allows the user to determine the identity of items in the natural world, such as trees, wildflowers, mammals, reptiles, rocks, and fish
a tool that allows users to identify items or organisms in a systematic and reproducible fashion
a tool that biologists use for helping identify a species
a tool that scientists can use to help identify a particular specimen
A system of identifying objects (such as plants,) in which a succession of paired choices leads progressively to identification of the object (the only remaining correct choice.)
a guide to identification of plants or animals consisting of a series of pairs of questions or descriptions.
a tool to help identify things - through progressive levels of choices, you can determine a species based on its observable traits
A tool used to identify unknown organisms. Based on a series of choices that eventually lead the user to the correct identity of the organism in question.
A tool in identification of plants. You are presented with 2 opposing questions at a time, and follow the key until you have identified the nomenclature for your plant.
A dichotomous key is a method for determining the identity of sometihing (like a butterfly, a plant, or a rock) by going through a series of choices that lead the user to the correct name of the item. At each step of the process, the user is given two choices; each alternative leads to another questions until the identification is completed. For example, a question in a dichotomous key for trees might be something like, "Does it have flat or needle-like leaves?" Dichotomous means "divided in two parts".
