MODULE 7
TAXONOMY
At the end of the lesson, you are expected to:
➢ Explain how the structural and developmental characteristics and relatedness of DNA sequences are used in classifying living things. ➢ Identify the unique/distinctive characteristics of a specific taxon relative to other taxa. ➢ Describe species diversity and cladistics, including the types of evidence and the procedures that can be used to establish evolutionary relationships.

Direction : Fill in the blank. Use the terminologies found in the first column to
complete the statement given at the second column.
Taxa 1. Linnaeus devised a system of naming organisms that is still in use today. Species 2. Organisms are placed in Taxa or classification groups. Binomial Nomenclature
- The taxon that is larger than a genius and smaller than an order is a(n) Family. Family 4. In Taxonomy an organism is given a 2-part scientific name that give the organism’s genus and species. Taxonomy 5. The smallest taxon is the Species , which is made up of organisms that share similar characteristics and can breed with one another. Linnaeus (^) 6. The science of naming organisms and putting them into classification groups is known as Binomial Nomenclature. SYNTHESIS

Basic Education Department Caloocan Campus B. DIRECTION: Find and match the scientific names of the organisms’ common names using the following key (show how did you use it). Number 1 is given as an example: 1.a) animal 1.b) not an animal go to 2 go to 11 2.a) has wings 2.b) no wings go to 3 go to 6 3.a) has feathers 3.b) no feathers go to 4 Ochloerotatus taeniorhynchus 4.a) flies high 4.b) does not fly high go to 5 Meleagris gallopavo 5.a) often yellow 5.b) not yellow Serinus canaria Haliaeetus leucocephalus 6.a) lives in water 6.b) lives on land go to 9 go to 7 7.a) has fluffy fur 7.b) no fluffy fur go to 8 Bos taurus 8.a) common pet 8.b) not a common pet Canis familiaris Mephitis mephitis 9.a) has fins 9.b) no fins go to 10 Haematopus ostralegus 10.a) razor sharp teeth 10.b) pegged, pointy teeth Carcharodon carcharias Tursiops truncates 11.a) green 11.b) not green go to 12 go to 13 12.a) grows tall 12.b) does not grow tall Pinus ponderosa Rhus toxicodendron 13.a) can be poisonous 13.b) not poisonous Boletus edulis Rosa sylvestris

DIRECTION: Read the idea below and answer the provided questions.
“The use of scientific names eliminates confusion between nationalities that may have
different common names for organisms by assigning them a universal name that acts
as a code. Scientists from one nation can converse with scientists from another about
a specific organism with the aid of the scientific name, avoiding confusion that may
arise from differing common names.” By Brenton Shields

1. What makes scientific name a universal name?
The scientific names were used in universal way for the classification of different kind of species (animals), scientists across the globe can recognize quickly the same species (animals). It refers to a binomial nomenclature and a lot of different scientific names from organism in Latin name.
2. Analyze why scientific names are better.
The scientific names are much better because of how descriptive it is. A
particular genus/epithet that pick-out some species from other connection to the
same genus.
