CLASS # 2: Medium-Sized Organisms

We found 9 different organisms within this class, which can be divided into 3 sub-classes/variations.

Common characteristics include size (5 to 7 feet tall); color (green); scent (none); taste (none); and appearance (leaves, branches, rooted in ground). There were variations in texture amongst the sub-classes.

CLASS #3: Commensalist or Parasitic Plants found on the New Land Never Explored in Previous History

We found three distinct types of commensalist/parasitic plants growing on trees in the New Land:

Mosses: Dark, soft and spongy, with tiny leaf-like structures.

Lichens: Thin growths, which spread and cover the tree.

Spores: Mushroom-type plants.

We classified each of the species we found by [m], [f] or [s] to indicate which group and a number to specify the species.

[m1] is a soft, medium green moss which grows in clumps and is very spongy. Seems to bulge out of the tree. Grows on [t1]

[m2] is a soft, dark green moss which looks and feels spongy, but does not bulge out of the tree like [m1]. Instead it grows closely to the tree. Grows on [t1]

[m3] is a leafy, light green moss which grows interspersed with [m2]. Its leaves are conic and narrow to point downwards. Grows on [t1]

[m4] is a very flat, dark green moss, so thin it seems painted onto the tree. Grows on [t2]

[f1] a very pale green moss which is flat and crumbly and seems to grow in a circular fashion on the bark of the tree. Grows on [t1]

[f2] similar to [f1] in color, this lichen grows in circular fashion but has leaves which resemble cabbage. Grows on [t1]

[s1] resembles a mushroom in form. It is a pale tan colour, with a curved stem usually growing horizontally from the tree, with the cap pointing straight upwards. Found growing on [t1]

We set off on our voyage to the little rectangle of plants outside the PSB. There we observed all sorts of new and exciting plants. We tried to classify them under the following system:

I. Leaves

1. Trunked — one common stem that branches up higher

1. Barked — rough outer coating

1. Oval leaves

circular

elongated

2. Star shaped leaves

1. Not Barked

1. Not-trunked — several stems that grow from a common point on the ground

1. Barked

1. Waxy leaves

Berries

No berries

2. not-waxy leaves

1. Not-barked
2. Oval leaf shape

One weed that had four leaves growing from a common point

3. Thin ellipse leaf shape

Serrated

Smooth edged

4. Rounded leaf shape

Smooth edged

Serrated

5. Heart leaf shape

2. No Leaves

1. Branching Structure

1. Ground-hugging (moss)
2. Upright

1. Non-Branching Structure

One type of organism was found in each of the categories that is not labeled with a letter or number. In general, we found more diversity in the leaved category. There were 20 types of organisms that we recorded. Given more time, we surely would have found more types of organisms. The best way to more accurately describe the organisms is to draw or photograph them or to save specimens.

One problem we encountered was the small number of examples of the larger plants, as well as the fern-like specimen and the ground-cover (moss-like). It is hard to draw conclusions from such a small sample. All other specimens were numerous — we definitely saw over 20 of each of the small plants — so we feel safe using them to draw initial classifications. However, even our larger classes had only a few sub-categories, so this should be considered inaccurate.

We took note of vein type, thinking it might prove useful in our classification system, but wound up not using it as a way to distinguish between organisms. Initial observations also led us to believe it might be helpful to categorize by height, but this system was also discarded, because of the recognition that a small plant could mature into a big one.

We would like further time to explore the island at greater length to see smaller details about the specific plants. A magnifying glass and/or microscope would be helpful in our observations.

Lab 1

The first thing we did was to brainstorm about possible categories, which took the majority of our time. The initial categories were Size, leaf shape, color, complexity, community, texture reproduction, number, visible root system, leaf or flowering, edibility, symbiotic/parasitic/neither. And rock. During the experiment we reevaluated the categories of rock, symbiotic/parasitical/neither, complexity, roots, reproduction, and edibility. We decided to eliminate or rework them into the following categories: size, shape, color, texture, leaf or flowering.

For the category of size we used relativity to surrounding organisms and to the human body. A height versus width comparison for some organisms which led some people to make a comparison with the numerous number of branches and how they might result in shape/size variations among plants.

With leaf shapes we compared the characteristics of serrated, rounded, pointy, general shape–oval rectangular etc. Which led us easily into the other category of color, which was defined by one team member as being relative to each other. Light green thus was the lightest green among all seen examples and dark the darkest among all seen examples. Some plants were examined for texture in comparison to the human skin. They were defined as rough, abrasive, soft, bumpy, and silky. This led many people to the observations of the presence of fruits or flowers etc., which some compared to probably reproductive techniques of the plant.

Number or recurrence was viewed as the number of the specimen in the given space. Some people took the square as a whole, while others blocked out small squares within the larger square to measure reoccurrence with in a small area. The group as a whole made observations about 13 different kinds of plants. Because our experimental methods differed there are different recording methods used throughout the group.

Using our fore knowledge of pre-existing classifications we divided the square into 4 initial categories and used the previous distinctions mentioned above to classify them into each of these major groups. In order to avoid naming it directly after things we knew, we divided into 4 groups M for moss related things, B for bush like things, G for grass like things, and T for tree like things. Using that system we found 1 M, 7 G, 2 T, and 3 B , each with nuances but forming a unique and undiscovered environment (and bonds between scientists).

Plant Life

Objective:

Classify plants in plot of land outside the PSB.

a) How many classifications

b) How many organisms fall into each class

c) Criteria/characteristic of each class

d) Changes in classification methods

e) Summary of findings

1. There are two main types of classifications which we designated as plants with branches and plants without branches growing on the ground.
2. Five organisms fall into the branch class and four organisms fall into the ground class.
3. Our criteria/characteristic for each class were basically the same with the exception of the category "fruit bearing" for the branch class. The criteria/characteristics were the number of leaf divisions, whether the leaves were round or pointy, the texture (soft or hard), and whether they were flat or had dimension.
4. As we continued to observe and classify the plants we found that it was necessary to add criteria/classifications.
