Answer 2

Answer:

Keys is the taxonomical aid based on contrasting characters generally in a pair called couplet​.

Explanation:

• A taxonomic tool called a "key" is used to identify plants and animals based on their similarities and differences.
• The keys are based on the two frequently opposing characters of a couplet.
• The description that best suits the unknown organism is picked from the two opposing descriptions of it, and based on the description chosen from the subsequent couplets, the type of organism and its position in the taxonomic hierarchy can be identified.
• A lead is any statement in a certain key.
• Monographs and flora are two other ways to record descriptions.
• The flora gives a detailed description of the habitat and distribution of plants in a particular location.
