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 is the name for a tree that doesn't shed its leaves in winter?
well, pine trees are a type of tree that keep their leaves all year round. pine trees have leaves that are almost more like little needles but not as sharp. we normally use pine trees as Christmas trees. there are probably other trees that don't lose their leaves as well, and I'm sure there are some that don't lose leaves until late Autumn or early winter. hope it helps :D
Evergreens.
Which tree has jagged edged leaves with long cream flowers like catkins?

Why don't palm trees uproot in hurricanes?
Sometimes they do. The main reason why it doesn't happen that often is that compared to the average tree the palms lose their leaves much easier than a tree loses its branches. And once the leaves have gone there isn't much left to catch the wind.
The palm tree also has a very flexible trunk and shallow-yet-regenerative root system as compared to a more "sturdy" tree such as an oak. This allows the palm to bend and sway with the wind. The shallow, thinner roots allow a palm to be blown down and quickly rebuild a root structure again.
If you've ever seen a palm on a beach, you'll notice that many of them begin at the ground growing sideways for a small length and then the trunk grows upward from there. This is usually where a palm has been blown over and rooted the tree where it has fallen sideways. The tree then grows upward from there.
The scientific (Latin) name for oak trees is Quercus.There are many species of oak tree, so a second word is appended to spcify the species. e.g. Quercus alba = White Oak Quercus virginiana = Eastern Live Oak Quercus fisiformus = Western Live Oak Quercus polymorpha = Monterey Oak
shrubs are smaller than trees. they have a woody stem and are less than six metres tall. the rose and hibiscus are some examples of shrubs. shrubs have a few stems that grow from the ground. unlike trees, the branches of shrubs grow close to the ground
What is the job of the branches in a tree?
A tree branch holds leaves which in turn catch the suns light which the tree needs to produce the fuel it needs to grow. The leaves and branches on a tree also catch water from rain and this water can cause the soil around the tree to be wetter. as well as this the shadow of the branches will cause a slowing in the evaporation of water from around the base of the tree. besides the branches catching the sunlight from above, branches also deny adequate sunlight for competing plants around the base of the tree to thrive further strengthening its position.
What is the habitat of a fir tree?
Fir Trees aka evergreens grow in most places except where it is extremely hot
How do eucalyptus trees reproduce?
They reproduce using cones also known as seeds.
Pine trees grow pine cones much like a flower grows blossoms. Inside the pine cone their are seeds that grow and mature. Then the cone falls off to the ground where it dries out. As it dries, the cone opens up so that the seeds can fall out. Birds and rodents grab some of the seeds and carry them a certain distance away. Little pine trees start where the seeds are on nice, moist soil.
The seeds of some pine trees are called, "Pine nuts", and are edible and delicious. You can buy them at your grocery store.
seeds are in the pine cone
leafy gametes.
A pine tree produces cones which contain the seed to produce further generations.
When is the best time to plant a dogwood tree?
Ideally, it's best to plant Dogwood start in very late winter, early spring: while the tree is still dormant and before it starts budding out leaves for the year. Really, though, any time of year is OK. Avoid super-hot days for any sort of planting as the heat could cause severe shock when combined with transplanting.
What is a teak an softwood hardwood or manufactured boards?
Pine is a softwood.
Almost all coniferous trees are softwoods. The actual hardness or density of the wood has little to do with the classification. - Generally if a tree is an angiosperm (bearing broad leaves and flowers) , then it's a hardwood. If it drops cones and needles it's a softwood.
Do all trees need to grow with sunlight?
No because plants go through photosynthesis in order to get food, animals are similar to humans in this sense.
Can trees grow in dry climates?
Where water is not found naturally in creeks and rivers, or as rainfall, farmers have to drill bores, going down hundreds of feet, to tap into underground water supplies (such as the Great Artesian Basin in Australia). The water is then brought to the surface via windmills. Water may also be diverted from rivers and dams into canals, which eventually feed into the farmers' paddocks. This is an inefficient way to get water, as much can be lost through evaporation.
Too many to count... until the last century, all medicines came from plants and animals, including trees. For example, the bark of a willow tree is full of compounds similar to aspirin, so it was used to treat fevers. As chemistry and pharmacy became more effective, these compounds were first isolated, enabling purer or stronger forms then obtainable in nature. Towards the later half of the last century, chemists began to use their knowledge of how the medicines work in the body (pharmacology) to design medicines that are better than what is found in nature. For instance, lidocaine is a synthetic compound that is very similar in pharmacological structure to cocaine (which comes from a tree); however, it works as a pain killer without some of the negative side effects of cocaine.
My favorite plant-derived medicine is caffeine from the coffee tree!
No, the alder is not coniferous. It belong to the birch family Betulaceae.
How do deciduous trees know when to drop their leaves?
If it loses its leaves in the winter, its deciduous. If not, its coniferous.
Acorns are the seed of the Oak tree and therefore they do not eat.
