3.)Adaptation of an Animal- My Norwegian Forest cat's fur length and thickness changes throughout the year. Thus since it is winter, her fur has adapted to the cold weather and grown thicker and longer. For as in the summer, her fur will start to decrease in thickness and come off.
8.)Arachnid- Spiders are apart of the class Arachnida. These invertebrate organisms always have 8 legs and two parts to their bodies. Some examples include: spiders, scorpions, and mites.
22.)Genetic Variation- Although these plants are all cyclamens, not all of them have the same flower color. The beginning plant of these cyclamens was one color, and as time went on different alleles have been shown to produce different phenotypes such as white, pink, red, and purple flower color.
28.)Modified Stem of a Plant- Modification of anything is due to an outside factor. The stem of this bamboo palm has modified so it has long spikes protruding out of the stem. This is most likely a modification that was made over time due to herbivores consuming it.
27.)Lichens-Although hard to see, in the corners of my pool is where lots of green algae builds up. A lichen is an organism that consists of a fungus and a photosynthetic partner working in a symbiotic relationship. In this case the fungus is working with green algae to create a lichen.
6.)Angiosperm- An angiosperm is a seed-producing plant and are the most diverse group of land plants. They can be distinguished from gymnosperms by examples such as plants that produce fruits containing seeds. The oak tree in this picture is an example of an angiosperm due to the fact that it produces acorns which are fruits that contain seeds.
26.)Homologous Structure- Homologous structures are things that are common because they have evolved from a common ancestor, no necessarily because they serve the same function. However, the stem of this common weed and the trunk of this tree come from a common ancestor, and share the same function. This could be mixed up with analogous however that means that they are from different ancestors.
20.)Fungi- Fungi are a group of eukaryotic organisms that include yeasts, molds, and mushrooms. They differ from plants mainly due to the fact that fungal cell walls contain chitin, while plant cell walls contain cellulose. As shown in the picture, these lactarius mushrooms are fungi.
30.)Modified Leaf of a Plant- Modification of anything is due to an outside factor. These berberis retinervia leaves have been modified to keep little parasites off. The modification is the spiky edges.
21.)Gastropod- Gastropods typically have a defined head, with two or four sensory "eyes" sticking out. Also, gastropods typically have a ventral foot. Although the snail is hiding inside of its shell, the snail is an example of a gastropod.
25.)Gymnosperm Leaf- Like angiosperms, gymnosperms are seed-producing plants. However, unlike seeds in angiosperms which are enclosed in some sort of ovary, gymnosperm seeds are unenclosed, or "naked." These seeds usually develop on the actual leaf. Conifer leaves, or more commonly known as Christmas tree leaves, are examples of gymnosperm leaves.
4.)Amniotic Egg- Amniotic eggs adapt terrestrially, and are enclosed in a shell that protects it from environmental factors such as water. Also, amniotic eggs consist of a food source and many membranes to promote growth. This chicken egg follows all of these characteristics because it has a shell, a yolk, and has been adapted terrestrially.
39.)Tetrapod- A tetrapod is any four-limbed organism that is a vertebrate. Thus, my neighbor's Korat cat is an example of a tetrapod because it has four limbs and is a vertebrate.
13.)Byrophytes(nonvascular plant)- Byrophytes are land plants that do not have lignin(part of secondary cell wall), and are plants that do not have vascular tissue. Hornworts, liverworts, and mosses are all examples of byrophytes. This moss is an example of a byrophyte because it does not have lignin, and has no vascular tissue.
41.)Vestigial Structure- During our ancestors time, wisdom teeth were used to grind up plants, and foliage. However, as humans started eating differently, there was no need for wisdom teeth to grind up our food. Currently, wisdom teeth still develop in humans but are usually taken out in teenage years. Thus, wisdom teeth are examples of a vestigial structure.
12.)Bilateral Symmetry- Bilateral symmetry when an organism is "divided" into two halves, where both halves are symmetrical. This southern magnolia leaf is an example because there is a central line that divides to planes which are symmetrical to each other.
11.)Artificial Selection- Before Darwin, farmers would only allow certain organisms that they desired to reproduce whether it was for eating, breeding, etc. This idea was later called artificial selection. Fruit is an example of artificial selection because since fruit is good, farmers, and even residential people decide to grow the fruit that they like and allow it to mature. Thus, this banana is an example of artificial selection because it was grown specifically by someone who wanted it.
40.)Unicellular Organism- A unicellular organism is explained by the name: an organism that consists of just one cell. Although eukaryotic, yeast is a unicellular organism that converts carbohydrates to carbon dioxide and alcohol by fermentation.
16.)Coelomate- A coelomate is a organism that contains a body cavity. A body cavity is any fluid-filled space in an organism. These crows are examples of coelomates because they have a body cavity called the pericardial cavity which is filled with serous fluid. It is located near the heart and visceral area.
19.)Eubacteria- Eubacteria have rigid cell walls, have flagellum for motility although some are non-motile. Also, they contain a circular chromosome structure known as the nucleoid. Gram-positive eubacteria is characterized by the high amount of peptidoglycan on the cell wall. Gram-positive eubacteria is known for the bacteria that causes strep throat and that that ferments in milk, creating yogurt. Thus, yogurt is an example of a eubacteria.
