Paulownia trees are among the oldest and finest trees around the world. The word tree has many definitions. Under botany a tree is defined as a perennial plant with branches, supporting leaves, and trunk. Under some situations the definition is restricted to plants of predestined height or woody plants. Bamboo, palms, bananas, and ferns are normally included in wider definition of trees.
Plants have varying lifespan some live up to a thousand years while some are seasonal. They grow to varying heights. The tallest existing tree is believed to be 379 feet, which is equivalent to 115.6 meters. It is assumed that plants can only attain a maximum height of 130 meters or 426 feet. They are among the earliest living things to have existed on the Earth. They are approximated to have been on the Earth 370 million years back.
Vegetation has evolved over time in response to varying climatic conditions and aspects such as competition. The increase in height is a significant feature of evolutionary adaptation. They grow tall as a result of increased competition over sun-light and space. Tall species easily access sunlight rays, which allow them to make food unlike dwarf species. The dwarf species have altered structures for their survival. They twist on taller species so as to access sunlight rays and for support.
They grow in great numbers in tropical areas. The tropics have the necessary growth conditions like sufficient sunlight, adequate rainfall, and fertile soils. The diversity of trees remains unclear since different species germinate in various places under varying climatic conditions. Botanists are still gathering data and surveying the different species.
A typical tree consists of parts such as branches, trunk or stem, leaves, and roots. Each part has a special function that it serves. The stem or trunk supports the branches. Roots provide support or anchorage as well as absorbing nutrients from the soil. Leaves photosynthesize under sunlight to provide food required for development and growth of the tree.
Plants play a great part in controlling pollution, moderating the climate, and reducing erosion. They clean excess carbon dioxide from the environment through carbon cycle. They maintain and hold soil strongly around roots thus minimizing erosion on soil. They are a rich source of fruits and home to birds. They are utilized as medicine in therapy of many illnesses. Some function as worship places and shrines for various communities.
Vegetation is currently threatened by human activities. Individuals are cutting down several plants during opening up of land for farming or cultivation. They are of very important to the surrounding and humans. The need to protect vegetation resulted in creation of worldwide organizations whose major job is to encourage planting of more plants. The world environment day is marked as a reminder to call upon people to protect the environment.
Paulownia trees are grown under the best conditions to increase chances of survival and growth in all types of climate. The tree nurseries in this region are tended to by the best agriculturalists. Professionals in this area conduct enough research to ensure they can adequately deal with all diseases affecting plants. They can be contacted through their websites on the internet.
