The importance of tee's and plants

  1. 1. The Importance of Treesand PlantsBy: Daniel walters
  2. 2. Part 1trees help us breathe and provide a home for quite afew kinds of animals and insects. They are thelargest and longest living organisms on earth. Togrow tall the tree has become a miracle ofengineering and a complex chemical factory. It isable to take water and salts out of the earth and liftthem up to the leaves, sometimes over 400 ft above.By photosynthesis the leaves combine the water andsalts with carbon dioxide from the air to produce thenutrients which feed the tree. In this process, as wellas wood, trees create many chemicals, seeds andfruit of great utility to man. Also, trees providerefreshing shade.
  3. 3. Part 1Trees are the lungs of the environment. They takemuch of carbon dioxide from the atmosphere andrelease oxygen via photosynthesis. They alsostore carbon in their roots, trunk, branches andleaves. Carbon makes up 50% of the weight of thewood in a tree. Therefore, the greenhouse gasload is reduced and effects of global warning arealso brought down. Further dead trees that getburied in soil eventually provide fossil fuels likecoal, gasoline products, etc.
  4. 4. Part 1Among all, trees have an indisputable role inbringing rain to earth. they provide a cover over thetop surface of earth preventing excessive heatingup by solar rays. Trees provide the human specieswith a constant supply of oxygen. Thisoxygen, which humans in turn use for survival, isproduced through trees as they intake variousamounts of carbon dioxide, which humans exhale.
  5. 5. Part 2trees convert carbon dioxide into oxygen through aprocess called photosynthesis. The light issunlight, shining on the tree, and the pieces beingput together are carbon dioxide and water. When atree has these three things it uses the energy fromthe sunlight to combine the carbon from the carbondioxide with the water to make a carbohydrate, ormore simply, a sugar. The sugar is food for thetree, just as people eat sugar and carbohydrates.When the tree makes the carbohydrate, there isextra oxygen from the water, which luckily for usgets released into the air, giving us the oxygen webreathe.
  6. 6. Part 2Each adult tree is made up of trillions of cells. Thecells in the leaves of a tree are wherephotosynthesis occurs, in special parts of the cellcalled chloroplasts. Each cell in a tree can containup to 100 chloroplasts. Inside of achloroplast, there are pigments that absorb light.The most common pigment, chlorophyll, isgreen, which is why most plants look green. Thetree leaves get water from the ground by drinkingthrough the roots, trunk, and stems of the tree.
  7. 7. Part 2The leaves also have tiny pores in them that theycan use to breathe in carbon dioxide the gashumans and animals breathe out from the air.Then, when light hits the chlorophyll, thechloroplast uses the lights energy to causephotosynthesis. The tree keeps the carbohydrateas food, and breathes out the oxygen through thepores on its leaves. With out tree’s in the world wewould have every day things
  8. 8. Part 3Trees help our soil remain healthy by reducing soilerosion and by creating a soil climate suitable formicroorganism to grow. There are over 23,000different kinds of trees in the world. A healthy treecan increase your property value by as much as 27percent while trees with dead branches, hollowcavities and other problems can decrease yourproperty value. Evergreen trees are green yearround because they do not lose all of their leavesin one season. Most will however lose some oftheir oldest leaves just before they produce newleaves in the spring. Some will lose part of theirleaves in the fall.
  9. 9. Part 3A tree can absorb as much as 48 pounds of carbondioxide per year and can sequester 1 ton of carbondioxide by the time it reaches 40 years old. Treeleaves are composed of many colored pigments --green chlorophyll hides them during the spring andsummer growing seasons. Shorter days and cooltemperatures in the fall cause the chlorophyll tobreak down and the other pigments to be see.Every state has an official State Tree. We do nothave a national tree, however, there is a campaignto have the oak adopted as our National Tree.Arbor Day, a day site aside to plant and recognizethe importance of trees, is not a national holiday. Iffact the day observed varies from state to state.
  10. 10. Part 3Tree wood is a highly organized arrangement ofliving, dying, and dead cells. The beginning andgrowth of tall woody trees in forests may haveplayed a key role in the extinction of the dinosaurs.Hundreds of food products) and food additivescome from trees. One large tree can lift up to 100gallons of water out of the ground and discharge itinto the air in a day. One large tree can provide adays supply of oxygen for up to four people. Eachyear, one person uses wood and paper productsequivalent to a 100 foot tree 18 inches in diameter.Over 5,000 products are made from trees.
  11. 11. Part 3Trees are included in most religions. Some holdcertain trees sacred; other use trees to help teachbeliefs. The story goes that Buddha received hisenlighten under the wisdom tree. Each year over600,000 people travel to Macon, Georgia to see240,000 cherry trees in bloom. The estimatedrevenue is over $6.5 million dollars per year.
  12. 12. Part 3Trees trap more of the suns energy than any othergroup of organisms on earth they are in essencebig batteries the largest on earth. Only 0.1% of thesuns energy is trapped by organisms treesaccount for 50% of all energy trapped by organism.Almost 98% of a tree is made up of six elements:carbon, hydrogen, oxygen, nitrogen, phosphorusand sulfur. Tree growth occurs in specializedtissues referred to as meristems. This tissue isfound at the tips of leaves and shoots. Growth indiameter occurs at the vascular cambium insidethe stem.
  13. 13. Part 4
  14. 14. Part 5Yes, trees do increase the property value and yesthey do make the place look nice and attract peopleand in all terms make more money for you. Thedownfall of all of this is if a storm comes through andtrees fall on your property. Trees each year causemore than 500 million dollars in damage to propertyand business. So when you want to attract people oradd more property value you have to make sure thatis for your best interest. The pun of the whole thingis that without trees we would die, but trees kill a lotof people every year and do millions of dollars indamage.
  15. 15. Quiz!!!How tall can tree’s grow to?How much weight dose carbon make up in atree?(it’s a percent answer)How many chloroplast are in a single cell in a tree?How many types of tree are there?How many gallons can a single beer typically lift?About how much can a well grown and treated treeincrease your property.
