Biological Classification Pogil Answers Model 3 Details

Classification of biological specimens is essential in any scientific study. A variety of classification models have been proposed over the years, with the most common being the Linnaean system. However, this system has limitations and does not reflect modern understanding of taxonomy. In this post, we will discuss a new model for classifying biological specimens – the Biological Classification Model 1 (BCM1). developed by Dr. J. David Archibald and colleagues. This model is based on cladistics, which takes into account evolutionary relationships between species. BCM1 is more accurate than the Linnaean system and can be used to classify all types of life forms, from viruses to complex organisms.

Biological Classification

How are organisms grouped, sorted, and classiÞed?

Why?

From the time we begin to talk, we start to name things. We like to see how things are related. It is natural then, that biologists would name and organize organisms into a classiÞcation system. In this activity you will learn about the major classiÞcation groups and how organisms are named.

6.Using the envelope outline from Model 1, classify the full address by writing the appropriate information in the ÒEnvelopeÓ column in Model 2.

Read This!

Carolus Linneaus (1707Ð1778) is known as the father of modern taxonomy. Taxonomy is the science of Þnding, describing, and categorizing organisms with the ultimate goal to name the species. In traditional Linnean taxonomy the seven major taxonomic groups are (in order from least speciÞc to most speciÞc)

Kingdom, Phylum, Class, Order, Family, Genus, and Species. Modern taxonomy categorizes the six kingdoms into three domains.

7. Use the Linnaean taxonomic groupings to complete the third column of the table above.

8.Which two of the three cats listed in Model 2 are most closely related? Explain your answer.

9.At which taxonomic level do the two cats you identiÞed in Question 8 separate?

10.What is the most speciÞc taxonomic grouping in which all three cats are the same?

11.What is different about the way the genus and species names are written compared to the other taxa?

POGILª Activities for High School Biology

12. The genus and species names are collectively referred to as the scientiÞc name. It is written in a form known as binomial nomenclature, a two-term Latin naming system. There are three rules for writing a scientiÞc name using this system. Analyze the information in Model 2 to complete the rules below:

Rule 1: The scientiÞc name is always written in ____ parts, with the genus name written

__________ and the species name __________.

Rule 2: The scientiÞc name is always written in ______________. If it is handwritten, it is writ-

ten in cursive or underlined.

Rule 3: The Þrst letter of the genus name is a ___________________ letter.

13.This system is used all over the world. Why do you think Latin is used instead of a more modern language?

14.Using this system, would it be possible for two different species to have the same name?

15.In LinnaeusÕs time, classiÞcation was based on the appearance of organisms. Think about the appearance of organisms such as tadpoles and frogs, sharks and dolphins, and penguins and eagles. What are the limitations of classifying organisms by only their appearance?

16.Considering advances in science, discuss with your group what might be a more reliable way to classify organisms. List at least three additional ways besides appearance.
