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 of the Branch of tree?
well its not really scientific, but tree branches are normally referred to as "limbs" by horticulturists and aboriculturists
What does the California red wood tree represent?
One of the most special things about redwood trees is that they are the tallest trees on Earth. Some redwoods have been found to be as old as 2,000 years, but most of those living today are no more than 700 years old.
What is the use of trees on the roadside?
Trees have numerous uses on roadsides, though it may depend on the density and alignment of the trees in how effective they are for any specific purpose:
1. Aesthetic, trees (generally) look nice. Trees and flowers can have a calming effect on drivers and promote a pleasant work commute for frequent drivers.
2. Wind / Dust / Snow screen. Trees can help break up incoming wind from surrounding areas, this may help prevent some of the problems caused by dust or snow blowing across the road. In areas without trees you may see wind/snow screens (fibrous plastic netting) used to attempt the same thing. Or mixing netting with trees can produce a screen while making it look better than an ugly plastic net by itself, and the trees may also act as additional anchoring points for the screen.
3. Natural drainage and/or soil erosion prevention. Trees will soak up some of the natural water in an area and along with other plants will help keep an area from becoming swampy or smelling bad from sitting pools of water. Or if the water is flowing frequently than the trees can be used to help keep soil anchored in place so that it does not completely erode an area quickly. While trees alone are not enough to keep water from either building up or washing away the soil, they can be used as part of an overall plan at handling water issues in a natural way.
4. Sound screen. If a roadway is near housing, there are really only three options to try and manage the sound levels: Walls, trees or a mixture of both. Depending on how far the housing is from the road and the level of traffic on the road it may be beneficial to reduce noise levels for the comfort of residents. Walls and trees (alone or in combination) are commonly used to help absorb some of the noise levels.
5. Pollution reduction. Cars create carbon dioxide, trees absorb it and turn it back into oxygen. With enough trees a highway's pollution levels can be reduced and help discourage smog from forming in high traffic areas. Some of the smoggiest cities in the world have highways systems that predate the now common practice of adding trees to roadsides during their building process. Cities with the largest density of trees near their roadsides consistently have better scores on air pollution tests. Trees alone will not solve pollution problems, but they are a measurable step in the right direction.
A highway engineer could probably list even more reasons for trees, but the bottom line: they are a helpful attempt at combating several of the drawbacks of building roadsides while also improving the overall look of the area.
question needs more information to be answered.
colour and condition of the leaves,
any visible insect or fungal pests/ pathogens
how often the plant is watered/ irrigated
location of the plant
how much exposure it gets to wind, light etc
Not all plants need to make seeds. Ferns and mosses for example do not have to produce seeds to spread.
What tree changes color in fall?
because they start to well kind of like swell up or die because winter is coming so they change color kind of like meat sometimes its red when you buy it but brown when you cook it
What is the scientific name for the Opepe tree?
The name would be Nauclea diderrichii. Family: Rubiaceae.
Why is a newly planted purple-leaf plum tree losing leaves in the middle of summer?
This could be a reaction to the tree's roots having too little, or too much water.
On newly-planted trees, you could try elevating it a bit or providing additional drainage.
Normally, a deciduous plum will only lose foliage in the winter.
Where did the ginkgo tree come from?
Ginkgo is native to temperate climates in eastern China, and can be found in deciduous forests in Japan and Korea. Ginkgo is considered a pioneer species, meaning it can quickly repopulate disturbed areas and grow in environments with sparse vegetation. It is also tolerant of a wide range of soil types and atmospheric conditions. Commonly found in temperate biomes, some of the environments ginkgo can be found in include:
- Deciduous forests
- Temperate grasslands
- Mountainous regions
- Urban areas
- Riparian zones
Ginkgo is most commonly found in deciduous forests and temperate grasslands, but can also be found in other biomes. As a result, it is considered to be one of the most widely-distributed tree species in the world.

What kind of trees gives us shelter?
Trees absorb carbon dioxide and release oxygen. By absorbing carbon dioxide, they are helping reduce the amount of greenhouse gases in the air. Greenhouse gases are known to eat away at the ozone layer, which protects us from harmful rays from the sun. Also, we breathe oxygen. By having more oxygen in the air, we are healthier.
How does water rise from roots to the top of trees?
It is just a natural thing.
Transpiration is the loss of water vapor through leaves because of diffusion or evaporation. This means that the water in plants are always moving from wetter areas to drier ones, despite gravity. Xylem, a network of microscopic tubes, pull water from the roots to the leaves. As it pulls, the tension created by transpiration is strong enough to to pull the water up to five hundred feet.
Look up the transpiration-cohesion theory, that might help in your understanding.

How are deciduous trees and coniferous trees different?
deciduous have leaves and coniferous have pines and needles.
The term conifer means cone-shaped. The term deciduous means that the tree loses it leaves every fall. The only species of conifers that are deciduous are Larches. If the tree in question has broad leaves, nearly all of them are deciduous.
Where do Mimosa trees grow in Canada?
The Mimosa, or the touch-me-not is grown as an ornamental plant. It lives in open and wide waste ground within tropical vegetation in its natural range.
What is special about softwood trees?
Because it is a thing you can use in building and making objects.
Can you tell a tree's age by its diameter?
Each ring is one year. You can tell what the weather was like on any year of the trees life by the width of the ring.
Unfortunately the tree is usually cut down by the time you can see them.
How is a pine needle different from a maple leaf?
They are needles, not leaves. ---An Answer-- Actually needles are leaves and they serve the same purpose. The only real difference in the two are their physical appearance and the the types of trees that produce them. Leafy tress are referred to as "Deciduous" and will lose their leave in the fall of the year when the weather turn cooler. Tress that produce needles are referred to as "Evergreen" trees and they will retain their needle like leaves year round.
