How do we classify living organisms? |
According to their shared characteristics, for example backbones or feathers |
|
|
What are the five vertebrate groups? |
Fish, amphibians, mammals, reptiles and birds |
|
|
What characteristics (method of gas exchange and reproduction) belong to reptiles and birds? |
Exchange gas via lungs, and give birth to an internally fertilised egg which must hatch |
|
|
What characteristics (method of gas exchange and reproduction) belong to mammals? |
Exchange gas in the lungs, and give birth to live, internally fertilised young |
|
|
What characteristics (method of gas exchange and reproduction) belong to amphibians? |
Exchange gases across moist permeable skin, and give birth to eggs which are fertilised externally |
|
|
What characteristics (method of gas exchange and reproduction) belong to fish? |
Exchange gases in the lungs, and lay externally fertilised eggs |
|
|
What are poikilotherms and homeotherms? |
Poikilotherms - vertebrates that are cold blooded so cannot control their body temperature Homeotherms - vertebrates that are warm blooded and can control their body temperature |
|
|
Classify each of the five vertebrate groups into poikilotherms or homeotherms. |
Poikilotherms - amphibians, fish,reptiles Homeotherms - birds, mammals |
|
|
What are the five kingdoms? What are their main characteristics? (Cell wall? Nucleus? Multicellular? Method of feeding?) |
Animalia - multicellular organisms that have no cell wall or chlorophyll and find food from their environment - heterotrophic Plantae - multicellular, have cellulose cell wall, and feed autotrophically - make their own food Fungi - multicellular - non cellulose cell wall, no chlorophyll, feed on dead matter - saprophytic Prokaryotes - single celled, with no distint nucleus Protoctista - single celled, with a distinct nucleus |
|
|
What are the seven classification group (in order if can)? |
Kingdom, Phylum, Class, Order, Family, Genus, Species Tip: Remember: Kings of Poland Can't Order Food off Great Snakes |

What is a hyrbid? |
The offspring of two different species. They are usually infertile |
|
|
What is a binomial name? |
A name for organisms to reduce confusion in different countries over having different names for the same organism. It is two part; the first word is the organism's genus, the second part is its species |
|
|
Why is the binomial naming system useful? |
It enables scientists to communicate information about lots of species around the world, and helps them to identify areas of biodiversity where conservation efforts are needed |
