Genus- surname so they share this with a group of other very similar organisms

Species name- christian name. Unique to that particular type of organism

= System in which the scientific name of an organism is made up of 2 parts showing the genus and species name.

MAMMALS teeth hair warm blooded single jaw bone inner ear bones produce milk-for youngs larger brain nourish their babies with milk

FISH cold-blooded live in water paired fins/gills/scales lay large number of eggs breath by drawing water over gills

AMPHIBIANS cold-blooded vertebrate lay eggs in water lack skin covering "2 lives" e.g frogs go through egg to tadpole to frog must stay close to water

REPTILES scales lay eggs on land can't regulate body temperature can absorb oxygen in water through their mouth don't use energy to fuel internal "furnaces"

BIRDS feathers lay eggs bodies adapted for flight beak rather than teeth hollow bones provide lightweight strength


MONOCOTYLEDONS 1 cotyledon strap like leaves parallel veins flower part divisible by 3 e.g. Kaffir lily

DICOTYLEDONS 2 coyledon broad leaves branching veins flower parts divisible by 4/5
