Transcript of Trees
Adapting and Assisting Trees
The sun provides it with the energy that is needed to help the tree pass through photosynthesis.
Water helps the tree in nutrients to feed it through leaf photosynthesis.
Trees respond with their environments by morphological and physiological responses.
Relocation and the available nutrients in the area also help the tree in survival.
The Tree Basics
A tree is so common that we rarely stop to think about its grandeur. We see them everyday, but how often do we realize the necessities trees provide us throughout our lives? It lives and breathes, just like us. Every part of a tree works hard to fulfill its job. It performs photosynthesis that keeps not only itself alive, but us also. So, throughout the next few slides remember that this stuff is important. Trees help keep us alive.
The Role of Trees
Maintains safe levels of oxygen and carbon dioxide in the atmosphere through photosynthesis and cellular respiration
Addressing climate change
Assists agricultural areas to be more sustainable
Prevents soil erosion
Provides shelter and food
Some trees help by having a repellent effect on insects
Trees and Other Organisms
Trees encourage biodiversity within its ecosystem
Trees have complex relationships
Symbiosis- interaction between two different organisms living in close physical association, typically advantage to both.
Mutualism- symbiosis that is beneficial to both organisms involved.
Commensalism- an association between two organisms that's indifferent
Every part of a tree offers potential niches for animals and insects
1/3 (4,000 out of 12,000) of the known ant species on Earth are only found in forest canopies

Photosynthesis and Cellular Respiration
Trees gather CO2 as they grow and use the process of photosynthesis to convert the suns energy into sugar, which cellular respiration then turns into ATP.
Forests reduce the amount of greenhouse gases in the atmosphere by absorbing CO2.
Deforestation accounts for almost 20 percent of global carbon dioxide emissions.
Agroforestry- is a land management system in which trees are grown around or among crops or pastureland. It combines agricultural and forestry technologies and invents more diverse, productive, profitable, healthy, and sustainable land-use systems.
Soil Erosion Protection
Forests provide erosion protection for river and stream banks
Acts as a filter for agricultural runoff
Protects water quality and fish habitats
Habitat for Wildlife
Provides shelter for birds, squirrels, beavers, etc.
Flowers, fruit, leaves, buds, and the wood from a tree is used by a variety of species
Bacteria and fungi decay parts of trees which make it easier for birds to build nests
Provides shade, reduces air and water temperatures
Increases health of aquatic ecosystems by providing shelter, habitat, and food
Benefits and Importance of Trees
Trees combat the greenhouse effect
Trees absorb CO2 and release oxygen back into the air instead. This decreases greenhouse gases, a major contributor to global warming
Trees clean the air
Trees trap pollutants and odors into the bark and leaves
Trees provide oxygen
In one short year, an acre of trees provide enough oxygen for 18 people.
Trees conserve energy
Three trees placed strategically around a single-family home can cut summer air conditioning needs by up to 50%.
Trees shield from ultra-violet rays
Let's Talk Leaves
A leaf with several leaflets or blades is called compound
Deciduous leaves are broad and flat. They fall off during Autumn
There are a few exceptions such as deciduous conifers- Larch, Cypress, and Dawn Redwood
Coniferous leaves are needle-like and they stay on all year round usually
Exceptions- Broadleaf Evergreens- Boxwood Rhododendron, Holly
A petiole is a part of a leaf that houses food and water conducting tissues
Economic Connections and
Most Profitable Trees
Flowering Dogwood trees are high on the list of buying items for landscapers
Hybrid Chestnut trees produce a combination of the taste from a American and Chinese chestnut. Also, its wood sells at a high price
Christmas trees (Fir Trees, Pine Trees, Spruce Trees, Cypress Trees, Cedar Trees) keep farms alive and profitable
Japanese Maples are another tree that is highly favored for homeowners and landscapers
Trees bring in income for many farmers. Some types of trees help the economy, because of the characteristics the tree has.
Environmental Problems Negatively Affect Trees
High levels of air pollution
Ozone pollution reduces tree growth, affect tree composition, and cause it to be more vulnerable to pests
Acid rain weakens trees by damaging their leaves which limits the nutrients available to them

Colorful patches are left by shedding bark and the wood is used for paper
