About This Quiz
Trees are some of the most beautiful, most mythical natural elements on earth, and when we behold their majesty, we realize just how small we really are. From the towering sequoias in the Pacific Northwest to the colorful cherry blossoms found in Japan, trees have been the subject of philosophers' pondering dating back to when words and thoughts were first recorded.
Trees hold magic that we can't explain. Their years on this planet far surpass ours, and we look to them to find peace, understanding and wisdom. In movies, literature and television, trees have powers, and they are the stuff legends and prophecies are made of. They are the tallest representation of the natural world, and they give us a sense that we are not alone (and we like it that way). You know that they hold great beauty, and you know that they're resilient, but what else do you know about them?
This quiz is all about trees. You'll be asked questions about how they grow, how long they live, and even their native lands. Let's see how much of a dendrophile you really are. Take this tree quiz, and you might just learn something new about these tall wonders.
Old age
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.

Giant sequoia
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.

Paint
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.

Cutting them down
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.

Chlorophyll
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.

Roots
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.

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

Pith
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
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.

Cambium
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.

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).

Yes, it happens all the time.
It is possible but not probable.
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.
No, that would never happen.

Having two trees grow into one
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.
