To summarize the difference between
trees and herbaceous plants:
-trees are larger than herbaceous plants
-trees have thicker stems
-trees have harder, woody stems & branches
-a tree’s leaves are usually larger
-trees have bigger roots
In general there are 2 major differences
between trees and other plants: size
and structure. Trees are bigger and
are woody, not soft stemmed. Shrubs
are also woody plants but they tend to
be smaller than trees and have more
than one stem.
The major parts of a tree or any plant,
(roots, stem and leaves) work together
to help it grow. Here is a brief
summary of their roles.
ROOTS
anchor the tree
take up water and minerals
from
the soil to feed the tree
STEM/TRUNK
provides support to the tree
contains the “plumbing” of
the tree,
where water and minerals
are carried
from the roots up to the rest of the tree
and sugars are
carried from the leaves
to other parts of the tree.
is the place where all other plant parts
are attached
a tree’s outer bark is made of hardened,
dead cells and serves to
protect the
tree from damage and disease.
LEAVES
like a mini-factory, leaves make food
for
the tree through a chemical
reaction
called photosynthesis.
Chorophyll-
the green color in
leaves
is necessary
for the
reaction
to
occur. Carbon
dioxide
from the air
is combined with
water
from the
roots, in the presence
of sunlight,
to produce sugar (glucose)
and oxygen.
