Entry #2 - Treesons to Enjoy a Hot Day

I'm sure by now many of you have caught on to my cheesy plant puns... yeah that was definately a thing. The idea behind this blog is for me to share the world of plants. In my first post I sowed my interest in plants into this blog soil. Now that the elements have settled through my second post, that seed is ready to grow. 

Today's fun facts are about TREES (secretly my favorite)! 

Now I'm in Arizona so the diversity of trees isn't really out there. The majority of trees around here are palms, mesquites, palo verdes and the ever popular, saguaro cacti. 

 If you don't believe they're trees just look at their 20 foot selves and tell me they don't compete.

However the main reason I bring up Arizona is that it is unarguably hot and shade is very valuable around here. When people go to park, the parking spot under the tree is the most sought out for. Now the question I want to bring up is why exactly is the shady area around the tree very popular since I am pretty sure that fact is true everywhere. 

So why is tree shade so treasured?

The answer: 

A tree is nature's air conditioner.

A tree makes cool air equivalent to that of 10 room-sized air conditioners that run for 20 hours. 
And that's all from ONE single tree.(1)

To understand how this is possible we have to look at a leaf...

Actually a bit closer...

Closer still...

Almost there...

There we go!

Those tiny little opening that look like lizard eyes are what a leaf uses to breathe. Yes, plants do actually breathe. Well transpire is more appropriate. The opening is called a stomata. Through the stomata transpiration occurs, which is the release of water through plants.(2) As the plant drinks up water from the soil, the plant uses maybe a small percentage of it and the rest is "exhaled" back into the air. The plant does this essentially to cool itself off from the energy it is using during photosynthesis to break up hydrogen molecules.(3) During a day, a leaf will "exhale" water that is many times more than its own weight. To put things into perspective, an oak tree will give off about 40,000 lbs of water in a year.(2)Thats enough water to fill about one and a half average pools. With all that water vapor leaving the plant, it's no surprise that the plant's vicinity should be cool. 

If you ever want to actually see this process in action, just wrap a plastic bag around a part of the plant and leave it for a few hours. When you return to the plant and remove the bag, you'll find that the inside of the bag will be covered with the condesation from the evaporated water the plant released. 

So next time you're complaining about a hot day and plan on escaping back into the confinements of your house, maybe just sit under a tree and enjoy the day. Although you might not want to sit under a saguaro. They can be a bit mean if someone gets too close.

Entry #1 - Rooting into Blogs

Me!

Blog World

I've known and heard about blogging but never really cared to actually find out what it is. When my college English professor introduced me to the world of blogs, I found it actually fascinating. Now I am staring my own blog and the big question pops up; where do I start? I have no idea what the do's and don't's of blogging were, so I do what any beginner to anything does: look for inspiration. I start going through various popular blogs to get a sense of where to start and essentially get an idea of where I want it to go.

I found that different things attracted me about some blogs and other things just made me yawn and scroll. Let me share a few with you.

The first blog I really like is by Martin Cherrett called World War II Today. At first my attraction to this blog isa bit biased since I really enjoy learning about WWII; however, what I really like about this blog is that it is right to the point. Cherrett displays a picture and elaborates on what exactly the viewer/reader is looking at. The content he displays are fascinating fact on what was going on during the current date of any of the years that WWII took place in. Cherrett is also really committed to his blog, keepiing up to date daily.

The second blog I diverted to is Elemental from the Wired science blogs. Despite the fact that Deborah Blum, the author of Elemental, hasn't written for a few months now, what is left over for the time being is interesting, her subject: poison. A bit unnerving at first since poisons don't generally have a nice rep, the topics Blum discusses are diverse. From history, to foods to the envirnment, you come to realize that toxins take many different forms.

Now the one style I am not very fond of belongs to Jason Kottke's blog, Kottke.org. His topics are very diverse. I don't mind the amount of information he has to offer, but the orginization of them all falls short of effective. 

What the other two blogs provide that Kottke's doesn't are illustrations. Sure, he links the things he talks about but I'd rather he flash up his blog more. It isn't very appealing to look at.

Based on what I've encountered in some blogs, I have gotten myself a pretty good idea on how I want this blog to grow and blossom.
