Plants are the most obvious of
life forms to the casual visitor to the Australian tropical rainforest; indeed,
for many people this may be initially all they can see.
-
While they vary
enormously, most are linked by their ability to make their own food through the
use of sunlight in a reaction known as 'photosynthesis', which occurs through
the most familiar of plant parts, the green leaf.
-
The tropical rainforests of the
Wet Tropics are the richest area of Australia for plant diversity.
-
There are at
least 1160 species of higher plants recorded from the north-eastern Queensland
rainforests, with new species being named every year.
-
The region has also been
recognized for it's high endemism; that is many of the species here are found
nowhere else.
-
The bewildering array of forms of the rainforest is presented here
in groups according to standard understanding of evolutionary order, that is,
with the primitive plants at the beginning, then 'progressing' through to the
flowering plants.
