classification Flashcards
define classification
the arrangement of animals and plants in taxonomic groups according to their observed similarities (including at least kingdom and phylum in animals, division in plants, and class, order, family, genus, and species).
define taxonomy
the branch of science concerned with classification, especially of organisms; systematics.
the classification of something, especially organisms.

define living non-living dead
Living is the condition of being alive. This refers to all plants, animals, fungi, and bacteria. Biologists have a set list of characteristics that can help determine whether an object is living. This list includes the ability to reproduce, the ability to grow, the ability to eat and the ability excrete waste, among other things.
Dead is the condition these objects enter when they are no longer alive. So, to be dead an object must once have been living.
Non-living is the condition of never being alive. Non-living could refer to inorganic matter. Rocks, for example are non-living. They are not dead, because they were never alive (as a rock, but they may contain chemicals that were once part of a living organism).
define an organism
an individual animal, plant, or single-celled life form
define a dichotomous key
A dichotomous key is a type of single-access key that offers only two choices at one time. These keys are commonly used in biology in order to identify an unknown animal or plant.

define vertebrate invertebrate
vertebrate The definition of vertebrate is something related to the bones in your back or spine. When you damage the bones in the back, this is an example of a time when you experience vertebrate injuries. The definition of a vertebrate is an animal that has a backbone or spinal column.
invertebrate an animal lacking a backbone, such as an arthropod, mollusc, annelid, coelenterate, etc. The invertebrates constitute an artificial division of the animal kingdom, comprising 95 per cent of animal species and about thirty different phyla.Compare with vertebrate.
define exoskeleton and endoskeleton
exoskeleton a rigid external covering for the body in some invertebrate animals, especially arthropods.Compare with endoskeleton.
endoskeleton an internal skeleton, such as the bony or cartilaginous skeleton of vertebrates.Compare with exoskeleton.
define ectoparasite and define endoskeleton
ectoparasite a parasite, such as a flea, that lives on the outside of its host.Compare with endoparasite.
endoskeleton an internal skeleton, such as the bony or cartilaginous skeleton of vertebrates.Compare with exoskeleton.
define mammals monotreme marsupials
mammals a warm-blooded vertebrate animal of a class that is distinguished by the possession of hair or fur, females that secrete milk for the nourishment of the young, and (typically) the birth of live young.
monotreme a primitive mammal that lays large yolky eggs and has a common opening for the urogenital and digestive systems. Monotremes are now restricted to Australia and New Guinea, and comprise the platypus and the echidnas.
marsupials a mammal of an order whose members are born incompletely developed and are typically carried and suckled in a pouch on the mother’s belly. Marsupials are found chiefly in Australia and New Guinea, and also in America.
name each of the characteristics of living things
Mr N Greww stands for:
M Living things must ‘M’ove R Living things can ‘R’eproduce
N Living things need ‘N’utrition
G Living things ‘G’row as they get older R Living things ‘R’espond to stimuli E Living things ‘E’xchange gases with their environment W Living things produces ‘W’aste W Living things need ‘W’ater
why is classifying living things important
There are many reasons that classifying organisms is important, such as helping understand the genetic relationships between different groups and species, helping with wide studies of organisms and helping to develop new biological sciences such as biogeography.
how do we classify living things
Scientists classify living things to make it easier to study and understand the behaviors, lives and evolutionary progression of millions of life forms. They use a system known as taxonomy to classify living things into kingdoms, phyla, classes, orders, families, genera and species according to their characteristics.
