Seed Structure

Seed is a means of reproduction, dissemination, and
the survival of a plant. Other than that,
for seed plants, seeds are the beginning of
new plant life outside its mother.
If plant seeds dikotil such as nuts,
beans, you split in half, you will
get a seed structure consisting of plumula,
hypocotyl, radicula, cotyledon and embryo.
Meanwhile, the structure of seeds of monocots,
eg corn consists of koleoptil, plumula,
radicle, coleoriza, skutelum and endosperm.
The parts of the seeds have their respective functions.
respectively for plant growth. In plant seed dikotil
or monocotyl, the plumula is the embryo's axis
grow upwards which will then grow into leaves
first, while the radicle is a growing embryonic axis
down and will become the primary root. In plants
monocots, eg corn, cotyledons are modified
into skutelum and koleoptil. Skutelum serves as a tool
absorbent food contained in the endosperm,
while the koleoptil serves to protect the plumula. Other than that,
in corn there are also koleoriza that serves to protect
radicula.
