Spore- A small, usually single-celled reproductive body that is highly resistant to desiccation and heat and is capable of growing into a new organism, produced especially by certain bacteria, fungi, algae, and nonflowering plants. This fungi I found on an old mushroom is covered on its outermost layer by many spores, in order to reproduce, thus allowing it to "grow" and thrive better in it's environment as it can then form new connections between its hyphae.

parasitism - a relation between organisms in which one lives as a parasite on another. The fungi growing on the mushroom gathers nutrients through the release of hydrolytic enzymes that catalyze cellulolysis or the hydrolysis of cellulose, present in the mushroom in the forms of protiens, lipids, and other organic substrates, allowing the fungi to create smaller molecules that may then be absorbed as nutrients. This relationship in which the fungi is dependent on the mushroom is an example of parasitism.

 Adaptation of an animal- An alteration or adjustment in structure or habits, often hereditary, by which a species or individual improves its condition in relationship to its environment. This bug demonstrates an adaptation as its color protects it from possible predators. 

bilateral symmetry- Symmetrical arrangement, as of an organism or a body part, along a central axis, so that the body is divided into equivalent right and left halves by only one plane. This bug looks the same on both sides, and as a result shows an example of bilateral symmetry.

Dominant vs. Recessive Phenotype- is the composite of an organism's observable characteristics or traits: This cat shows a mix of both dominant grey and recessive white furred phenotypes.
