Co-ordination and Response
In plants
Auxin
Auxin is a chemical commonly found on in the tips of plants to elongate the plant towards better conditions.
Tropisum
Geotropism
def:tropism effected by gravity
Negative Geotropism
means that the part of the plant is growing away from gravity (eg. shoots)
positive Geotropism
means that the part of the plan is growing towards gravity (eg. roots)
Phototropism
Positive Phototropism
means that the part of the plan is growing towards light (eg. roots)
Negative Phototropism
means that the part of the plan is growing away from light (eg. roots)
def: tropism effected by sunlight
In humans

Pupil Response
see far
lens is stretched
see near
lens is relaxed (fat)
bright
pupil is smaller to take in less light
dark
pupil is larger to take in more light
Reflex Arc
stimulus
reseptor

synapses in neurons (axon)
vesicles containing neurotransmitters are stored near the synapses
released when there is a electrical impulse
vesicles release the neurotransmitters to the synapse
receptors collects the neurotransmitter.
then the electrical impulse carries on and the neurotransmitters are recycled.
Homeostasis
Sweating
shivering
Vasoconstriction
Vasodilation
Rate of respiration
Erector muscle of hairs
Capillaries near surface of skin will dilate of contract
Temperature Regulation
Osmoregulation
excretion
