Paulownia Trees And General Information On Trees

By Harriett Crosby


Paulownia trees feature amongst the oldest and best trees around the globe. The term tree holds many definitions. Under botany trees are defined as perennial plants with trunks, supporting leaves, and branches. Under special circumstances the definition is narrowed to woody plants or the plants of a predetermined height. Palms, ferns, bamboo, and bananas are included in the wider definition of trees.

Plants have distinct lifespan some survive for many years whereas some grow seasonally. They grow to various heights. The present tallest tree is estimated to be 115.6 meters or 379 feet. Botanists tend to believe that plants can only grow 426 feet or 130 meters as the maximum height. They are among the first living organisms to have inhabited the Earth. It is estimated that they occupied the Earth surface 370 million years back.

These organisms have evolved with time in response to varying environmental conditions and aspects like competition. One observable evolutionary adaptation of trees is increased height. They grow tall because of competition for sunlight and space. Tall plants easily access sunlight, which enable them to photosynthesize unlike short ones. The short ones have modified structures to make sure they survive. They coil on tall trees in order to access sunlight 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 is made up of parts like roots, trunk or stem, branches, and leaves. Each part has a unique function that it is meant to serve. The trunk or stem supports branches. Roots provide anchorage or support in addition to absorbing mineral ions from the soil. Leaves manufacture food under sunlight, which is needed for development and growth of the plant.

Plants play a great role in moderating the climate, controlling pollution, and reducing soil erosion. They clear carbon dioxide from the atmosphere through carbon cycle. They hold soil firmly around their roots hence reducing soil erosion. They are a source of fruits and habitat to birds. They are applied as medicine in treatment of many illnesses and diseases. Some serve as shrines and worship places for various communities.

Plants are presently under threat as a result of human activities. Cultivators are cutting down trees when they open up land for cultivation. Plants are of great importance to both the surroundings and humans. The need to preserve vegetation led to creation of universal organizations whose responsibility is to encourage and teach people to plant more plants. The world environment day is observed as a reminder to people to conserve the environment.

Paulownia trees are cultivated in good conditions to increase the possibility of growth and survival in all climatic conditions. The tree nurseries in Paulownia are attended to by well trained agriculturalists. Experts in the area research adequately to make sure they effectively deal with plant diseases. They may be reached via their blogs over the internet.
