The Tree Quiz

A tree can keep growing as long as nothing kills it. It never dies from old age. However, if it doesn't have enough water, if too many bugs eat it or the roots rot, it will die. It kind of makes you think about how old a tree can actually get.

You may know it as a redwood tree. They are often found in the Pacific Northwest region of the United States. These trees are so large and vast that their canopy holds species not yet discovered by scientists.

That's right; pine trees grow everywhere except Antarctica. While they may look a little different in the warmer regions, they are all related, and you can simply look around wherever you are to feel like you're at home.

While you can use various parts of a tree to create painting tools, a tree itself cannot create a painting. However, we're sure if you give it enough time to learn, it might be able to figure it out.

To figure out the age of trees, scientists had to cut them down and count their rings. Imagine the scientist who cut down a 4,900-year-old tree just to see how old it was. What a tragedy.

Having well-placed and maintained trees around your home will increase its value as well as decrease the time it is on the market. However, if your trees are overgrown and surrounded by weeds, you might have a problem.

We all know that trees absorb carbon and turn it into oxygen. However, not many of us realize that trees can only absorb about 48 pounds of carbon a year. All of the trees in America only absorb 10% of our emissions.

You can spot a ginkgo biloba pretty easily by looking at its leaves. They are fan-shaped and have several different healing properties. Ginkgo trees used to go by the name maidenhair tree.

A total of 50 to 65 pounds of almonds from a single tree might not seem like a lot, but when you consider how many trees are in an almond orchard, you soon realize that a good yield might look like around 4,500 pounds of almonds in a season.

Weeping willows are probably some of the most identifiable trees in the United States. The Wisconsin weeping willow is a fast growing tree, reaching nearly 40 feet high in just a few years.

That's right, nearly 1/3 of the United States is a forest area. While you might think this is a lot, remember that these trees only absorb about 10% of our carbon emissions every year.

Trees absolutely need their leaves to live. The leaves of trees turn sunlight and water into sugar and energy for the trees with the help of chlorophyll. If you're old enough, you remember the "Billy Madison" scene that explains this.

In general, trees in urban areas and cities don't grow to be very big. There are several reasons for this. First of all, their root structures can damage building foundations, and they have to be removed, and secondly, city conditions aren't so perfect for a tree's life.

Pawpaw trees don't look like much, but they are fruit-bearing trees that are considered the largest in North America. The pawpaw fruit is a tropical fruit that is a mix between a banana, a mango and citrus.

The tallest tree currently living in the United States is over 2,000 years old, and it can be found in the Redwood National Park (California). It is a coastal redwood tree (of course) that is taller than most buildings.

Tree roots grow to find water in the ground. This helps them live during freezing months as well as when weather conditions are harsh. Roots are very strong, and they can even penetrate cement and rock.

When you look at an image of a tree, you usually see the big set of leaves that makes the top. This is the crown. Those leaves are held to branches making the shape of the entire tree.

To put it simply, a deciduous tree loses its leaves in the winter, and an evergreen tree doesn't. While there are several species under each category of trees, knowing that the two are different can help you pass this quiz.

Every tree has a small dark spot in the middle of the trunk. You can only see it if you take a core sample or cut the tree down. The pith carries nutrients up to different parts of the tree to ensure growth.

Heartwood separates sapwood from the pith of the tree. It helps support the tree as it grows and it is usually a darker shade than the rest of the trunk of the tree. It is made of dead sapwood.

The cambium is found between the bark and the sapwood of a tree. It is usually a thin layer of cells. You can feel it if you pull the park off of a tree. As the cambium hardens, it leaves a ring on the trees, which is how we tell their age.

Tomatoes grow on vines where avocados, apples, and bananas all grow on different kinds of trees. Fruit-bearing trees grow in orchards (not farms), and they require a lot of water to ensure healthy yields.

The Eastern cottonwood tree is usually found in the eastern United States. They get their name from the way their seeds spread — it basically looks like it's raining cotton balls throughout town.

The bark of white oak isn't white. As a matter of fact, white oak trees get their name from their leaves. There is a white underside to the leaves. White oak trees can grow about 1 to 2 feet per year.

People buy mature trees for more than lumber and paper production. Some cities purchase large evergreen trees for their holiday exhibitions, and some large companies purchase mature trees for their landscaping.

Every once in a while, the United States takes inventory of its forests. The last inventory showed that there are nearly 247 billion trees that have a diameter of over 1 inch living in the United States right now.

While it depends on what species of tree you're looking at, some larger trees can have up to 200,000 leaves at a time (as long as they're healthy and mature). That's a lot of raking, come autumn.

There are dozens of different kinds of stone fruits, and peaches are one of them. They have thin skin that is covered in fir (or fuzz). They are one of the most delicate fruits available for sale in the United States.

While you may think that your bath is relaxing with eucalyptus oil in it, there are tons of other uses for this tree. The nectar makes delicious honey, and the leaves have healing elements to them.

Pistachios are one of the most expensive nuts you can get per pound, but they are worth every penny. You can make pretty much everything out of them, because they are a softer nut.

The star magnolia gets its name from the flowers that blossom on it. As you may have guessed, these flowers are star-shaped. These trees are native to Japan, but they can be transported easily when they are young.

Dragon blood trees or Socotra dragon trees get their name mainly from their sap. It is a red sap that makes it look as though the tree is bleeding from time to time. This can be frightening if you don't know a lot about trees.

Coconuts have a lot of different definitions. However, when you look at it from a strictly scientific perspective, the coconut is a seed that grows on trees. It's a seed that has a lot of flesh and produces milk, but it's a seed nonetheless.

There are dozens of different species of palm trees. However, there is no fir palm available for sale. Perhaps one day someone will cross breed the genes and mess with the DNA to make one.

Bottle palms (or hyophorbe lagenicaulis) are stout palm trees that look very much like large bottles or jugs. When pruned properly, these trees make for excellent landscaping choices in the American Southwest.

That's right; an avocado can stay ripe on the tree for nearly a year before it dies or needs to be harvested. That means (and follow along here) that avocados are ALWAYS in season. However, farmers have decided to do large harvests only a few times a year (which is why our avocados are so expensive).

Koa trees are the second most common tree that can be found in Hawaii. The word Koa in Hawaiian means brave or fearless (or even warrior). We suppose you have to be a brave tree to live where volcanoes erupt.

Trees can freeze to death, but the truth is many cold climate trees freeze a little bit each year anyway. They don't die from freezing, because once they thaw they require nutrients again, and their cycle continues.

In case you weren't aware, there is an entire subculture of bonsai enthusiasts who grow, trim and sculpt bonsai trees as a hobby. If you want to sign up, you simply have to contact your local bonsai enthusiast branch.

There is an art called tree grafting that brings multiple trees together to create sculptures. Each sculpture can take nearly 30 years to complete, but it is possible. What you do is cut into the trunks or branches of two trees, then tie them together at the wet part. They grow into one another, making a seamless root.
