Trees
Above ground, trees and shrubs perform important environmental services by providing food and shelter to people and wildlife, oxygenating the air, and beautifying the landscape. Below ground, their roots open up critical passageways for the movement of air, moisture, and soil food web members.

What does a mahogany tree look like?
The Mahogany tree is a 'straight' thick skinned, tall, and majestic. It's soft rounded and gentle leaves are a dominating, yet peaceful sight to behold. <br/>It's true beauty (like most of us) lies within. Once mature and processed it's internal beauty helps create some of the most splended furniture you'll ever see.
Most conifers are evergreen; however, there are exceptions such as Taxodium distichum, or Baldcypress. Conifers are characterized as trees with either needle or scale like leaves and cone bearing but being evergreen is not a requirement of this classification.
Yes, and other things like swamps, rainforest's, jungles.
The Bodhi tree at the Mahabodhi Temple is called the Sri MahaBodhi. According to Buddhism, after his Enlightenment, the Buddha spent a whole week in front of the tree, standing with unblinking eyes, gazing at it with gratitude. A shrine was later erected on the spot where he so stood, and was called the Animisalocana cetiya (q.v.). http://en.wikipedia.org/wiki/Bodhi_tree
Pine trees bear clusters of leaves, called "needles," or "pine needles," in clusters.
Yes

How many years for peach trees to bare fruit?
A peony will grow well in the right conditions but some take a long time to flower, in some cases several years. Modern hybrid varieties will flower quicker.
How Does a Tree Grow? (Terms appearing in Bold Print may be found in the Glossary of Tree Terms)
Trees grow in two ways. In a young shoot, bundles of cells form. These are a primary kind of wood known as provascular tissue. As the shoot grows, a layer of cambium forms across and between the primary bundles where each year, cells in this layer divide and grow. As the cambium divides, wood and bark cells form. Cells pushed outward form the bark which eventually splits and falls off and is replaced. A tree's upward growth occurs at the tip of each twig. (See diagram below). The inward growth of the cambium forms the main part of the trunk and is called xylem. Tiny tubes which transport water and minerals from the roots up the trunk and branches to the leaves make up the xylem. Leaves need this water to help them make food from sunlight. The outward growth is protected by a layer of phloem. The phloem is made up of tiny tubes that transport the sugars from the leaves to the rest of the tree. If the phloem is damaged the tree will die. Roots may not go down deep but they can spread outward as far as the tree is tall. Roots anchor trees to the soil and absorb water and soil minerals needed for growth. Some trees have deep tap roots; others have a spreading system of roots. Roots as they push through the soil are aided by a cap that forms over the tender growing point of each root. Beyond this point, myriads of root hairs extend into the soil, increasing increasing the surface area of the root and increasing the amount of water the tree can take up.

From Fun With Science: Trees and Leaves,
Rosie Harlow and Gareth Morgan, Warwick Press, 1991 In some trees a difference in color exists between the outer part of the wood, the sapwood or alburnum, and the inner part, the heartwood or duramen. The sapwood is the light part of the wood as seen in cross section. It is the most recently formed wood, the circle farthest from the central cylinder. Sapwood is the physiologically active part of the wood through which the sap rises and has a high level of humidity. Thus, it is susceptible to rot and vulnerable to attack by fungi and insects. The heartwood is the part of the trunk nearest the center, the older part, which makes up the greater part of the trunk. It is simply a form of the sapwood modified by aging, and differs from it in its greater compactness and darker, more intense color. Humidity is lower in heartwood and its cells walls are thickened by deposits of tannins, resins, starchy substances, coloring matter and oils. This part of the plant is already dead, performing only the functions of support and storage.

Which nuts do not grow on trees?
Peanuts. But then they are actually not nuts but rather legumes. They grow under the ground like potatoes.
What is the national tree of Scotland?
Two billion-plus describes the number of trees in Scotland, according to Scotland's Trees, Woods and Forests, published with an introduction by Allan Wilson, Deputy Minister for Environment and Rural Development April 2, 2002. That number involves one of every 14.83 acres (6 hectares) in Scotland. Its total rises yearly since Scotland's new and replanted (from already harvested) woodlands increases by 24,710.54 acres (10,000 hectares) every year.
What types of trees grow in the Atlantic?
The Atlantic region of North America is home to one of the world's greatest pine forests where you may find shortleaf pine, longleaf pine, loblolly pine, and a host of others. In addition to pines, there are many other species such as cottonwoods, magnolias, poplars, oaks, juniper, hemlock, sycamore and many more.
Only to contain them within the space available. The only pruning needed otherwise is to cut off the previous years flowers in the early spring.r
What shrubs are poisonous to cows?
One of the worst plants is "Ragwort". althouth it tastes bitter and generally horses wont eat it in the field, often bad farmers will quite happily make hay bales with dead ragwort inside. It is a very slow poison and damages kidneys etc. If enough is eaten by the time you notice your horse is ill, it is too late and the damage is done and the vet will have to put your horse down. If you see it growing in your field pull it out and burn it. Dont let it seed. Make sure you buy hay from a very reputable dealer and check the hay for dried ragwort first.
Leaves grow on trees. Every autumn, the trees shed their leaves in preparation for the winter months. Prior to leaves falling off of trees, they typically change from green to yellow, red, orange or brown. When the leaves fall off the trees, they dry out and turn brown.
Excessive deforestation can lead to a range of negative environmental effects, including loss of biodiversity, disruption of ecosystems, and increased carbon emissions that contribute to climate change. The removal of trees also affects soil stability and can lead to erosion, water cycle disruption, and diminished air quality. Additionally, the depletion of forests can threaten the livelihoods of communities that depend on these resources, leading to social and economic challenges. Sustainable management practices are essential to balance human needs with environmental preservation.
