"Tree explained in 140 characters."
I have a Bachelor of Science in Forest Resources. I probably know more about trees than the average Joe (although my specific area of study was turning trees into paper). And, as you probably know, 140 characters was what Twitter used to allow (now it's 280).
I had to think about what do trees do? How do they do it? What is the net result?
Here's what I came up with:
Trees grow up, turning air into sugar, sugar into structure, structure into height. They can be huge or merely tall. They make oxygen for us
The last period is missing because that's the 141st character.
Trees take air, that is, carbon dioxide, plus water and turn it into glucose, a sugar. Then in a process I don't understand (never learned) they take glucose and turn it into cellulose which then becomes the structure of the tree. Some trees are tall and some hare huge (such as the California Redwoods and Sequoias).
So what do you think of my 140-character description of trees? Let me know in the comments below.
