Classification Flashcards
Definition of Movement
The ability to move parts of itself, to change position.
Definition of Respiration
The ability to release energy from sources of food, normally glucose, usually using oxygen.
Definition of sensitivity
The ability to detect a stimulus in the environment and to respond to that stimulus.
Definition of growth
Te ability to permanently increase in size, mass and complexity of an organism.
Definition of reproduction
The ability to produce offspring by either sexual or asexual means.
Definition of Excretion
He ability to remove waste products that have been produced by the body’s chemical reactions (metabolism).
Definition of nutrition.
The ability to OBTAIN and USE NUTRIENTS to provide the energy, growth and health needs of the organism.

Fungi (saprotrophs)
Decompose material to get energy and grow
Bacteria (monera)
Single celled organisms with no nucleus
Protists (Protista)
Single-celled organisms with a nucleus
Name the five kingdom of life

What does Classification do
Classification puts organisms into groups based on common features and evolutionary proximity
Chordata - phylum
They are called vertebrates
Have a spinal chord
Fish - class
Scales Gills Fins Cold blooded External fertilisation
Mammals - class
Fur/hair
Lungs
Mammary glands
Warm blooded (can regulate body temp.)
Reptiles - class
Dry scales Lungs Lay eggs Ear holes Cold blooded (can't regulate body temp.) 4 or 0 legs
Birds - class
Feathers Lungs Lay eggs Ear holes Warm blooded (can regulate body temp.) 2 legs + 2 wings
Amphibians - class
Moist, smooth skin
Lungs + gills
Lay eggs
Cold blooded (can’t regulate body temp.)
4 legs (usually)
Webbed feet (piece of skin between fingers)
Annelids - phylum
Long, cylindrical bodies Segmented bodies Layer of mucus Bristles (tiny hair at sides) Round mouth end + pointed anus end
Nematodes - phylum
Long, cylindrical bodies
Pointed at both ends
Most are parasites
Not segmented bodies
Molluscs - phylum
Muscular body
Most have hard shell (calcium bicarbonate)
Arthropods phylum
Jointed legs Segmented bodies Waterproof exoskeleton (molt+shade)
Crustaceans - class
Hard (calcified exoskeleton) 5-20 pairs of legs Two body segments (cephalothorax+abdomen) Two pairs of antenna Gills Compound eyes
Insects - class
3 pairs of legs
All arthropods with wings are insects (but not all insects have wings)
One pair of antennae (usually)
3 body segments (head, thorax, abdomen)
Arachnids - class
4 pairs of legs
2 body segments
Several pairs of simple eyes
Fang-like structures to poison their prey (chelicerae)
Myriapods - class
More than 20 legs
Many body segments
1 pair of antennae
Simple eyes
Mosses - Phylum
No vascular tissue (they’re so small that nutrients diffuse)
Angiosperms - Phylum
Flowering plants
Monocot - class
One cotyledon
Vascular bundles scattered in stem
Leaf veins parallel
Flower petals in multiples of 3
Dicot - class
Two cotyledons
Vascular bundles on a distinct ring
Leaf veins on netted pattern
Petals in multiples of 4 or 5
Magnification triangle
