Observations
Preliminary method
« On your tree, use a compass to find out which side of the tree is
north.
« Then place your grind against the tree trunk and count how many
squares have growth on them.
« Write your results down in a table and repeat for east, south and
west.

Preliminary information
Pleurococcus is the most common green algae and grows on the tree
trunks, poles and stonewalls. It is mostly found on the north side of
the trunk at the bottom. To grow it needs a lot of, moisture and shade
although it still needs sunlight and water like most trees and plants.
However green algae do not have any roots. They do not have any leaves
or stomata therefore it does not have any water saving protection.
They are single celled and have to grow in clumps to avoid
In this story the trees developed just like the characters. They are sitting around talking when Turtle says the word “beans”. Taylor thinks that she says the word “bees” but doesn’t realize that Turtle is looking at the wisteria vines. “Will you look at that, ‘I said. It was another miracle. The flower trees were turning into bean trees”(194). When one gets to this point it is close to the end when every character is finding their place. They are still developing but it’s not as messed up as it was in the beginning. Just like the trees they first start out as a seed and at some time they will become mature enough to produce what they are supposed to
3. Chapter 1, page 5, #3: “Moving through the soaked, coarse grass I began to examine each one closely, and finally identified the tree I was looking for by means of certain small scars rising along its trunk, and by a limb extending over the river, and another thinner limb growing near it.

Most of the trees have straight trunks with thin smooth bark with branches that don’t branch out until around 100feet

To some an acorn is just an acorn, nothing more than a nut. The acorn with its tough leathery outside and rich amber color signifies nothing more than the commencement of autumn. To others it represents a great deal of potential. This tiny seed has the ability to endure many adverse effects including long periods of cold temperatures, drought, and human interference. The fragile acorn contains all the necessary elements to become the giant, majestic oak that has come to signify strength. When the conditions are favorable, the little nut will thrive and become an impressive adult tree providing oxygen and shade as nature intended. The most important factor to the budding tree is the environment. Like all other living things, the acorn needs care and ideal circumstances to develop properly. This is also true for humans and their offspring. Creating the perfect environment for an infant to flourish is quite possibly, the single most important factor to the success of a well-adjusted, adult human.
It scattered on the hard footpaths where it had no chance to take root, on the thin soil above the limestone rock, in the soil with the thorny roots, and some in the rich soil, which was free from such. The birds ate the seeds that lie exposed on the hard footpaths. (B, 285; C, 74; D, 672; H, 165) " Here the soil had different capacities, but each yielded a good harvest according to its ability." (Hobbs, 165) "
A biofilm is a layer consisting of various combinations of many different organisms, autotrophic and heterotrophic. They are dense, organized communities of cells, encased in a self-produced slime. The bacteria grow together in water like atmospheres, attaching to a solid surface, forming a small ecosystem. Biofilms are known as a micro-environment, a micro-habitat, or a slime matrix. They help decompose dead organisms and recycle carbon and nutrients.
There have always been many different trees are found in the forest. Tall ones, round of leaf and with broad branches spread open in welcome. Short ones are found here as well, with thin trunks and wiry limbs they sway in the breeze. A wide variety of foliage in the emerald grove dancing merrily to the whispers of the wind. In this quiet thicket, a different type of tree grows, too. They stand resolute, patient, and ever growing.
Examine a leaf cross section. Sketch and label its parts. Take note of the position of xylem and phloem and the other parts of the plant leaf.

The next line is represented by, “s)”. This symbol can represent a sense of closure that started in line one. It is almost as if the leaf “)” has turned around in its falling. The last three lines, beginning with “one”, describes the isolation of a leaf from the tree. It can also symbolize being alone and is also symbolized in line eight by the isolated “l”.
The tree is very much like a queen, wearing its dress of leaves. I would not reach out and touch it—because it would be rude. At the shoulders of the tree—the branches fork off into three directions. The thick branches hold up more green leaves—the delicate kind—shaping the head of the tree like a mushroom. The tree resembles a green Queen Amadalia—young and bright. When I looked up at her, you see the sunlight reflect off her hair—the leaves—creating a peaceful glow. It blurs everything, however, and I had to stop looking. The wind does blow the leaves, but it is so lightly that you can barely tell. The fountain near by spurts out water in this direction.
On the edge of a small wood, an ancient tree sat hunched over, the gnarled, old king of a once vast domain that had long ago been turned to pasture. The great, gray knees gripped the hard earth with a solidity of purpose that made it difficult to determine just where the tree began and the soil ended, so strong was the union of the ancient bark and grainy sustenance. Many years had those roots known—years when the dry sands had shriveled the outer branches under a parched sun, years when the waters had risen up, drowning those same sands in the tears of unceasing time.
