Biology : Taxonomy And Classification

Front 1

Why do biologists classify organisms?

Back 1

To organize and keep track of the enormous variety of life forms, to better understand evolutionary distances, and to examine the relationships between organisms.

Front 2

What is the difference between classification and taxonomy?

Back 2

Taxonomy is the classification of something, especially organisms. And classification is classifying something according to shared qualities or characteristics.

Front 3

Why do we use scientific names instead of common ones?

Back 3

Cause they are not specific to a particular species.

Front 4

How do you write a scientific name?

Back 4

In italics, next to the non-scientific name.

Front 5

Why do we use latin?

Back 5

So that communication and collaboration is possible, even though it’s a dead language. It’s also not changing and is the root for many languages.

Front 6

What are the major classification levels?

Back 6

Kingdom, Phylum, Class, Order, Family, Genus, Species

Front 7

What levels make up the scientific name?

Back 7

Binomial Nomenclature, also Genus and Species.

Front 8

List the 3 domains and 6 kingdoms.

Back 8

D: Archaea, Bacteria, and Eukarya

K: Eubacteria, Archaebacteria, Protista, Animalia, Plantae, and Fungi

Front 9

Several genuses make up a _________. Several families make up _______. Several __________ make up a class. Several classes make up a ___________, and several phyla make up a __________.

Back 9

Family, orders, orders, phylum, kingdom.

Front 10

What’s the relationship between classification levels and relatedness?

Back 10

It tells the relationships and connectedness of the species or organism you are trying to identify.

Front 11

What are the 3 characteristics used to put organisms into the 3 domains?

Back 11

If its Eukaryotic, or Prokaryotic or if it is multicellular or unicellular.

Front 12

What characteristics of each of the 6 kingdoms? (List them and study them!!!)

Back 12

Animalia: Multicellular, Eukaryotic, Heterotrophic

Plantae: Multicellular, Eukaryotic, Autotrophic

Fungi: Multicellular, Eukaryotic, Heterotrophic

Protista: Both Multi and Uni, Eukaryotic and Both Auto and Hetero

Archaebacteria: Unicellular, Prokaryotic, both Auto and Hetero

Eubacteria: Unicellular, Prokaryotic, both Auto and Hetero

Front 13

How did Aristotle and Linnaeus help with classification?

Back 13

Aristotle: grouped organisms into Plant or Animal.He then subdivided animals into water, land, or air dwellers.

Linnaeus: developed system of classification into seven categories, each group more specific than the last

Front 14

What is a dichotomous Key?

Back 14

a tool that allows the user to determine the identity of items in the natural world, such as trees, wildflowers, mammals, reptiles, rocks, and fish.

Front 15

Why is a dichotomous Key helpful?

Back 15

Because they help you identify what the species is.

Front 16

What is a phylogenetic tree?

Back 16

a branching diagram or "tree" showing the inferred evolutionary relationships among various biological species or other entities—their phylogeny—based upon similarities and differences in their physical or genetic characteristics.

Front 17

When classifying organisms is appearance more important or evolutionary relationship? Why?

Back 17

Yes, because it shows the genes and traits that will be passed down the generation.

Front 18

Autotroph?

Back 18

make it’s own food.

Front 19

Binomial nomenclature?

Back 19

when each organism is given a specific name based on their genus and species

Front 20

Cilia?

Back 20

slender, microscopic, hair-like structures or organelles that extend from the surface of nearly all mammalian cells (multiple or single).

Front 21

Classification?

Back 21

classifying something according to shared qualities or characteristics.

Front 22

Eukaryote?

Back 22

a type of cell that contains a nucleus.

Front 23

Flagella?

Back 23

a whip-like structure that allows a cell to move. They are found in all three domains of the living world: bacteria, archaea, and eukarya

Front 24

Heterotroph?

Back 24

organism that is not able to make it’s own food.

Front 25

Homeostasis?

Back 25

the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes

Front 26

Linnaeus?

Back 26

he developed system of classification into seven categories, each group more specific than the last

Front 27

Multicellular?

Back 27

Cell organization in an organism that have more than one cell.

Front 28

Nucleus?

Back 28

the home of the cell.

Front 29

Prokaryote?

Back 29

a type of cell that does not contain a nucleus

Front 30

Species?

Back 30

a large group of organisms.

Front 31

Taxonomy?

Back 31

the classification of something, especially organisms.

Front 32

Unicellular?

Back 32

Cell organization in an organism that have one cell.
