classification

Question 1

Biodiversity

Answer 1

Variety of organisms that live on Earth

Question 2

Classification

Answer 2

Grouping organisms together on basis of shared characteristics

Question 3

Taxonomy

Answer 3

Classification of organisms according to similarities and differences

Question 4

Systematics

Answer 4

The branch of biology that deals with classification and nomenclature; taxonomy.

Question 5

Cladistics

Answer 5

A method of classification of animals and plants that aims to identify and take account of only those shared characteristics which can be deduced to have originated in the common ancestor of a group of species during evolution, not those arising by convergence.

Question 6

Nomenclature

Answer 6

The body or system of names used in a particular specialist field.

Question 7

Binomial nomenclature

Answer 7

The system of nomenclature in which two terms are used to denote a species of living organism, the first one indicating the genus and the second the specific epithet.

Question 8

Hierarchy

Answer 8

Of the nature of a hierarchy; arranged in order of rank.

Question 9

Taxon/ Taxa

Answer 9

A taxonomic group of any rank, such as a species, family, or class.

Question 10

Clade

Answer 10

A group of organisms believed to comprise all the evolutionary descendants of a common ancestor.

Question 11

Kingdom

Answer 11

The highest category in taxonomic classification.

Question 12

Phylum

Answer 12

A principal taxonomic category that ranks above class and below kingdom, equivalent to the division in botany.

Question 13

Division

Answer 13

Any subsidiary category between major levels of classification.

Question 14

Genus

Answer 14

A principal taxonomic category that ranks above species and below family, and is denoted by a capitalised Latin name

Question 15

Species

Answer 15

A group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding. The species is the principal natural taxonomic unit, ranking below a genus and denoted by a Latin binomial

Question 16

Domain

Answer 16

A distinct region of a complex molecule or structure.

Question 17

Prokaryote

Answer 17

A microscopic single-celled organism which has neither a distinct nucleus with a membrane nor other specialised organelles, including the bacteria and cyanobacteria.

Question 18

Eukaryote

Answer 18

An organism consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus. Eukaryotes include all living organisms other than the eubacteria and archaea.

Question 19

Heterotrophic

Answer 19

A heterotroph is an organism that obtains food by feeding on other organisms

Question 20

Autotrophic

Answer 20

Ability to make its own food

Question 21

Saprotrophic

Answer 21

Obtaining nutrition from dead or decaying matter

Question 22

Unicellular

Answer 22

Consists of a single cell

Question 23

Multicellular

Answer 23

Have or consists of many cells

Question 24

Motility

Answer 24

Motility is the ability of organisms and fluid to move or get around

Question 25

Homologous traits

Answer 25

Homologous traits are traits that are similar to one another due to shared ancestry

Question 26

Analogous traits

Answer 26

Comparable in certain respects, typically in a way which makes clearer the nature of the things compared.

Question 27

Dichotomous key

Answer 27

A dichotomous key is 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.

Question 28

Phylogenetic tree

Answer 28

A phylogenetic tree is a diagram that represents evolutionary relationships among organisms.

Question 29

Node

Answer 29

A point in a network or diagram at which lines or pathways intersect or branch.

Question 30

Common ancestor

Answer 30

An ancestor that two or more descendants have in common.

Question 31

Cladogram

Answer 31

A branching diagram showing the cladistic relationship between a number of species.
