Classification

Question 1

Classification

Answer 1

the division of organisms into groups, or classes, based on specific characteristics

Question 2

Taxonomy

Answer 2

the science of describing, naming, and classifying organisms.

Question 3

Kingdom

Answer 3

the highest category in taxonomic classification.

Question 4

Phylum

Answer 4

A taxonomic rank at the level below Kingdom and above Class in biological classification, especially of animals.

Question 5

Genus

Answer 5

A genus is a taxonomic rank used in the biological classification of living and fossil organisms in biology. In the hierarchy of biological classification, genus comes above species and below family.

Question 6

Species

Answer 6

a species is the basic unit of biological classification and a taxonomic rank. A species is often defined as the largest group of organisms in which two individuals can produce fertile offspring, typically by sexual reproduction.

Question 7

Mammalia

Answer 7

Mammals are any vertebrates within the class Mammalia, a clade of endothermic amniotes distinguished from reptiles and birds by the possession of a neocortex, hair, three middle ear bones and mammary glands.

Question 8

Primate

Answer 8

A primate is a mammal of the order Primates. In taxonomy, primates include two distinct lineages, strepsirrhines and haplorhines.

Question 9

Hominid

Answer 9

any of the modern or extinct bipedal primates of the family Hominidae, including all species of the genera Homo and Australopithecus.

Question 10

Class

Answer 10

a taxonomic rank. Other well-known ranks in descending order of size are life, domain, kingdom, phylum, order, family, genus, and species, with class fitting between phylum and order.

Question 11

Order

Answer 11

a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. Other well-known ranks are life, domain, kingdom, phylum, class, family, genus, and species, with order fitting in between class and family.

Question 12

Family

Answer 12

is one of the eight major taxonomic ranks; it is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks above the rank of genus.

Question 13

Protista

Answer 13

A kingdom consisting of unicellular or simple multicellular organisms that possess nuclei and cannot be classified as animals, plants, or fungi. Protoctists include the protozoa, algae, Dinomastigota, Oomycota, and slime moulds.

Question 14

Fungi

Answer 14

any of a large division (Eumycota) of thallophytes, including molds, mildews, mushrooms, rusts, and smuts, that are parasites on living organisms or that feed upon dead organic material: fungi lack chlorophyll, true roots, stems, and leaves, and reproduce by means of spores

Question 15

Plantae

Answer 15

the taxonomic kingdom comprising all plants.

Question 16

Bacteria

Answer 16

various species of which are involved in fermentation, putrefaction, infectious diseases, or nitrogen fixation.

Question 17

Archaebacteria

Answer 17

a group of microorganisms, including the methanogens and certain halophiles and thermoacidophiles, that have RNA sequences, coenzymes, and a cell wall composition that are different from all other organisms: considered to be an ancient form of life that evolved separately from the bacteria and blue-green algae and sometimes classified as a kingdom.

Question 18

Domain

Answer 18

a field of action, thought, influence,

Question 19

Dichotomous Key

Answer 19

a key used to identify a plant or animal in which each stage presents descriptions of two distinguishing characters, with a direction to another stage in the key, until the species is identified

Question 20

Linnaeus

Answer 20

a Swedish botanist who created the current system for classifying plants and animals. An example of Linnaeus is the founder of the taxonomy system.

Question 21

Chordata

Answer 21

any of a phylum (Chordata) of animals having at some stage of development a notochord, gill slits, and a dorsal tubular nerve cord: the phylum includes the vertebrates, tunicates, and lancelets.

Question 22

Animalia

Answer 22

The kingdom Animalia, or Metazoa, includes all animals. Animals are multicellular, eukaryotic organisms, which are heterotrophic, meaning they obtain nutrition from organic sources. Most animals obtain nutrition by ingesting other organisms or decomposing organic material.
