Module 2. E BIOLOGYContentsTrees are the tallest and largest free-standing. organisms on earth. It is thought that there are between 60,000 and 100,000 tree and shrub species in the world, the difference being a reflection of the difficulty of de. ning a “tree”. In this guide, we have used the definition that ‘a tree is regarded as a ...
Tree anatomy and morphology represent how a tree stands against wind and gravity, (Figure 1) as well as how it functions and how it looks. Understanding trees requires the discipline of learning and using basic scientific and botanical terms. Tree anatomy can be as simple as crown, stem, and roots. Some people delve deeper to know

Tree roots comprise an entire system which is almost completely underground in the case of most tree species. While the roots typically do not extend any further than12 to 18 inches below the surface of the ground, they can spread outwards to be double the size of the tree canopy. The type of roots a tree produces will depend on the species, though...
The crown of the tree is the tree canopy, which is made up of limbs, branches, stems, and leaves. For most trees, the leaves of a tree make up around 5% of the total tree, while the branches account for around 15% of the total tree mass.
The trunk of the tree is the central, usually upright, wood part of the tree. It bridges the gap between the root system of the tree and the crown of the tree, and it can look very different depending on the species of the tree. Some trunks may be long and slender, others may be short, or stumpy, and some may be multi-stemmed so that one tree appea...
The leaves of a tree can be evergreen or deciduous, with evergreen leaves remaining on the tree all year around, while deciduous trees shed their leaves each fall or winter and produce new leaves the following spring or summer. Leaves are typically green, but they can also come in other colors, such as red, orange, yellow, white, blue-green, and gr...
Flowers are usually one of the more attractive parts of the tree, though this isn’t always the case, and sometimes they can be quite small and insignificant. Flowers appear on most trees in the spring or summer, though some will continue to bloom sporadically or continually throughout the year.
The fruits of trees may or may not be edible depending on the type of tree. Many trees, such as pear trees, cherry trees, apple trees, and apricot trees, produce fruits which are specifically cultivated to be sold as food production on a mass scale. Trees which produce fruits which are not edible for humans will usually be feasted on by birds and o...
The branches of a tree can take the shape of large limbs which extend from the tree’s trunk, or they may be smaller, coming from along the lengths of limbs. The branches of a tree will dictate how big the canopy of the tree is, and therefore the type of shade it produces and the amount of space that tree will require.
Anatomy of a Tree Read the descriptions for each part of a tree. Write the name of each tree part in its corresponding box on the diagram below. Make sure to color the tree after labeling the tree parts! Branches: woody parts of the tree that grow from the trunk. Leaves: food-making part of a tree - where photosynthesis takes place.
inner bark (phloem) - tubular cells distribute sugars made in the leaves around the tree. cambium - living tissue growing phloem outward and xylem inward. sapwood -conductive cells (xylem) bringing water and minerals up from roots and around the tree. heartwood - retired sapwood that forms the strong central pillar of the tree and does not decay.

Myth: The root system is more or less a mirror image of the top of the tree. Myth: Most tree species have deep taproots; if a tree's taproot is cut, the tree dies. Myth: A tree's roots extend to the tips of the branches. Myth: Tree species are "deep-rooted" or "shallow-rooted." Myth: Roots seek water.
