Key is a taxonomical aid used for the identification of organisms. It contains a series of statements or questions that help in the identification of an organism. Each statement in the key is called a lead.
Explanation:
A key is a tool that helps in identification of an organism by presenting a series of questions or statements. Each statement or question is called a lead or a couplet. The lead or couplet helps in distinguishing the characteristics of the organism being identified.
For example, in a dichotomous key, the key is divided into two parts, and each part represents a characteristic of the organism being identified. The user is then asked to choose which characteristic best describes the organism, and this helps in narrowing down the options until the organism is identified.
Therefore, each statement or question in a key is called a lead, and it helps in the identification process of the organism being studied.
