| TAXONOMY & The Invertebrates
ACT #1: Introduction to Taxonomy (please read pg. 356-357) A) Copy the evolutionary tree (Fig. 23.2) B) Why is this diagram so important? (In your opinion or if you don�t it is important, why does Mr. Liao think it is important?) ACT #2: Why Classify Things? We will be studying a lot of different types of animals. Its easier if these organisms could be studied as groups instead of individually. Classification is simply the process of grouping objects/animals/plants that have certain things in common. Why do we classify? Write down these three reasons. (1) To organize things (2) To show relationships (3) To identify or locate something easily. ACT #3: Taxonomy and the Father of Taxonomy Use www.geocities.com/mtcarmelbiology Click �taxonomy lab� A) Who is Linnaeus? What was his contribution to taxonomy? B) What is taxonomy? C) What are taxa? Taxon is the singular form. ACT #4: Binomial Nomeclature Linnaeus decided that every plant of animal should have a 2-word scientific name. This 2-word naming system is called binomial nomenclature. Under this system, all living organisms have a scientific name consisting of the Genus and the species. A) Turn to page 286-287. What is the difference between Genus and Species? Which one is always capitalized? Which one is always in small case? B) Scientific names, when handwritten or type are usually underlined, however in textbooks the scientific name is printed in italics. 1. Humans: _____________ ______________ 2. Black Bear: _____________ _____________ 3. Corn: _____________ _____________ 4. Housefly: _____________ ______________ ACT #5: Latin Endings Scientific names in Latin seem to scare most students. Here�s a little tutorial to make you become more familiar with Latin. As you learned in the cell lab, the plural of nucleus is nuclei. Why? Copy down the table below to help you determine proper endings. For Latin words you will come across in biological classification. Gender Singular Ending Plural Endings Masculine -us (ex: cactus) -I (ex: cacti) Feminine -a (ex: ameba) -ae (ex: amebae) Neuter -um (ex: bacterium) -a (ex: bacteria) (A) Write down the common names for these scientific names: Acinonyx Jubatus = _______________ Hippotigris Grevyi = _______________ Vatanus Komodoensis = _______________ Romalea Microptera = _______________ Panthera Pardus Japonensis = _______________ Rana Pipiens = _______________ Giraffa Camelopardus = _______________ (B) Sometimes the genus part of a scientific name is also the common name of an organism. When this is the case, the name is not normally capitalized or underlined. For ex: Paramecium Caudatum is just called Paramecium. Rhinoceros, geranium, hippopotamus are common names which also are part of the scientific name of the organisms. Can you think of 2 more examples? 1. _____________ 2. _____________ ACT #6: The Kingdom of the Living World (text Pg. 287) (A) List the 5 kingdoms we are most familiar with. Give me a summary of the characteristics associated with each. (B) Our text mentions the possibility of 6 kingdoms. How would that work? Which kingdom is broken down into two? Why would scientists want to do this? ACT #7: The Amoeboid Protozoans (text Pg. 320 � 322) (A) What are the earliest, structurally most simple eukuryotes? (B) How are these protistans different from bacteria? (C) How many protistan species consist of the protozoans? (D) How are some different kinds of protozoans animal-like? (E) How would these animal-like protozoans reproduce? |
