PROPERTIES OF LIFE
:
D ordered
order organisms are
highly
→
→ within
every cell ,
atoms make up molecules , which make up cell components / organelles etc .
2) evolutionary adaptation →
adjustment / changes in behaviour,
physiology & structure of an
become more suited to an environment
organism to .
environment
eg pygmy
. seahorses camoflage into
3) regulation →
organisms require regulatory mechanisms to co ord internal
functioning
-
:
regulation of nutrient transfer
:
response to stimuli
ul environmental stress
:
coping
.
eg jack
. rabbit maintains
vessels in its
steady body temp by regulating blood flow
through ears .
4) energy processing
→
energy req . to comp metabolic processes .
eg photosynthesis
5) growth and development →
occurs according to instructions held in
genes .
a) reproduction →
sexual / asexual in order to create new
organisms
.
7) response to environment →
living things must respond to stimuli
eg sunflowers that towards
turn the sun .
eg
humans pull away from a
frame
