Using Identification Keys Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what's on both sides.
  • Make sure you understand the information on each card. If something's unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

  • Look at the question or prompt on each card and try to remember the answer before flipping it over.
  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It's useful to remember specific examples to understand these concepts better.

What is an identification key in biology?

An identification key is a set of questions that helps you find the name of an organism.

What is a branching or dichotomous key?

A branching or dichotomous key is a key where each question has two possible answers, leading you to the next step.

What is a characteristic in an identification key?

A characteristic is a visible feature of an organism, such as leaf shape or number of legs, used to tell it apart from others.

How do you use a branching identification key?

Start at the first question, choose the answer that matches your organism, then follow the arrow or instruction to the next question until you reach a name.

Why are identification keys useful in fieldwork?

Identification keys help you quickly and accurately name the species you find when sampling habitats.

How is an identification key different from a picture guide?

A picture guide shows many pictures to compare, while a key asks you simple questions that narrow down the choices.

What kind of characteristics should you use when making a key?

Use clear, easy-to-see characteristics that do not change quickly, such as colour, size, or number of body parts.

What is a numbered identification key?

A numbered identification key uses a list of numbered steps with paired statements, and you follow the numbers until you reach a name.

What is the first step when making your own simple key?

First, list all the organisms you want to include and write down their different characteristics.

What should you do if an organism does not fit any choice in the key?

Check the organism and the key again carefully; if it still does not fit, it may be a species not covered by that key.
