Trees matter

Abbey information report

Trees have many parts such as leaves, trunk, branches, twigs they can also make and do cool things

Parts of a tree
There are many parts to a tree these parts include roots, trunk leaves and many other parts
Roots
The roots a life support to a tree they collect water, nuntries and food they also grow underground
Trunk
The trunk is made of 5 parts bark, cambium, sapwood, heartwood and finally the last layer is called pholem .
Crown
The crown lives at the top of a tree and it shades the roots. The leaves are another life support to a tree they breath for the tree through a process called *photosynthesis
Twigs
Twigs store sugar and water

Photosynthesis
*photosynthesis is a process that trees use to breath . First they breath in Co2and then they breath out O2

Chlorophyll
Chlorophyll is the main pigment that provides colour. Chlorophyll gives plants the green colour because it reflects green light and absorbs red and blue light. The chlorophyll stops
in autumn and the leaves float away in the wind.

Types of trees
There are two main types of trees. They are evergreen and deciduous
An evergreen tree is a tree that is always green but losses old leaves that get replaced with new leaves.
A deciduous tree loses all of there leaves in autumn and grows all of there leaves back in spring

In conclusion all tree parts are very important and without one part the tree would not function properly.
