Last Pictures


A woody stem is one that grows in a rigid wood-like consistency. While trees are famous for this, over shrub plants such as blackberry bushes also have woody stems. This is a blackberry plant.

Herbaceous stems are ones that remain green, limber, and non-woody. Many plants follow under this category including waxy plants such as cacti, allow, and other such plants. Of course normal plants also fall under this category, like this onion plant.

When people think of symmetry they usually think of splitting something in half and getting an even shape on each side. Radial symmetry, on the other hand, is when you have an object that looks the same depending on however much you rotate it. If it weren't for the tears, then this toadstool (or is it a mushroom?) would have perfect radial symmetry, meaning that no matter how far or to what degree it is turned it will still have the same shape.

Pollinators, like this butterfly (It's in the center on the flower), are important for the reproduction of angiosperms. These creatures have developed ways of drinking the nectar the plant hold to lure it so that they accidentally pick up its pollen to take it to the next one.

This tick is a parasite: a creature who uses another creature for its own gain while harming the other creature, but not directly killing it. Numerous parasites will steal nutrients from its host, such as water, blood, or other parts. Many examples of parasites are Ticks, mosquitoes, tapeworms, and leeches.

Insects, a type of arthropod, have numerous common themes that separate them from other arthropods. first they have three pairs of legs, unlike arachnids who have eight. They also have three different body parts: The head, thorax (chest-like part), and the abdomen (the butt-like part). This ant is an insect and shows all these traits.

Cellulose is a form of sugar that plants produce to create their cell walls. It is the reason why plants are crunchy and the main building-block in tree bark. In order for organisms to be able to break down cellulose they usually need a special enzyme or bacteria in their stomachs to break it down into simpler sugars.All plants are autotrophs, meaning they all produce their own energy by absorbing it from the sun. I chose this picture of a tree because it looks like its reaching to the sun for more light.


Arthropods, translated from Greek meaning "joint foot", are any creature that has an exoskeleton and numerous joints upon their legs and such. The different categories of Arthropod are Insect, mentioned above, Arachnids, having four pairs of limbs, Crustaceans, aquatic Arhtropods like crabs and lobsters, and Bugs, such as millipedes and centipedes. The creature in the picture is a spider, which is an arachnid.

Kaitlyn's 10 collected items.

Cnidarians have a diplobastic, radially symmetrical body that includes a gastrovascular cavity with a single opening that serves as both mouth and anus. Cnidarians include corals, hydras, and jellyfish, like this one that I found next to our dock.

Arthropods have segmented bodies, hard exoskeletons and jointed appendages including, their pincers, mouthparts, legs, backfins, and antennae. Crabs and lobsters are good examples of an arthropod.
An ectotherm is an organism that gains most of their heat from external sources, such as sitting in the sun or in the shade, like this snake I found by a pile of wood.
An exoskeleton is a hard case deposited on an animal's surface, with each growth spurt an arthropod, like this cicada, must shed its old exoskeleton and begin to develop a new one.

This slug is an example of a gastropod. Many gastropods have a shell that the animal can retreat into when threatened, they move by using a rippling motion, often leaving a trail of slime behind them. They also usually have a distinct head with eyes at the tips of tentacles, like this slug I found inside of our canoe.

An insect is segmented into three regions; head, thorax and abdomen, like this grasshopper I found on the side of our house.
Lichens grow on the surfaces of rocks, rotting logs, trees, and roofs in various forms. I found this leaflike lichen on a tree outside of our house.
An autotroph is an organism that uses energy from the oxidation of inorganic substances or the sun, like this baby spruce tree, to make organic molecules from inorganic ones.
A female pine cone contains microscopic female gametophytes inside an ovulate cone.
A tomato is an example of a fleshy fruit with seeds, some other examples of fleshy fruits with seeds are grapefruits, nectarines and plums.

Angiosperm - a plant that produces flowers and seeds, the latter of which are enclosed in a protective structure (e.g. a fruit). A tomato plant is an angiosperm because it starts out as a flower bud with a seed-containing ovary; then, as the ovary grows larger, the flower becomes a tomato, and the seeds are found in the fruit. This angiosperm is from our vegetable garden... even though the tomatoes are technically fruits.


Animal that has a Segmented Body - an animal with a body divided into segmented units, like cars in a train, that often group together into larger functional units. A beetle is an animal with a segmented body. Its body is divided into three regions: the head, the thorax, and the abdomen, each of which has segments of its own. The beetle's legs alone are composed of five main segments. I found this beetle near some grass in my friend's yard, but by the time we photographed the little bugger, it had crawled onto the sidewalk.




Arthropod - an invertebrate with an exoskeleton, a segmented body, and jointed appendages. Butterflies do not have bones (an internal skeleton). Instead, each part of their bodies is covered with a hard coating that protects it (an exoskeleton). Like the beetle above, which too is an arthropod, this butterfly has a segmented body, as well. Attached to the butterfly's head, thorax, and abdomen are various appendages, such as six legs and four lovely wings. The picture of this butterfly on our windowsill is an example of an arthropod.
