Asexual Reproduction

Asexual Reproduction - Asexual reproduction describes the formation of offspring without fertilization, gametes (reproductive cells), or the exchange of genetic material with a second organism. Because this process only requires one parent, offspring are always genetically identical. This is necessary for single-celled organisms (bacteria/archaea) and some plant varieties. Two common methods of asexual reproduction include binary fission (division of the parent organism) and fragmentation (splitting off parts of an organism; common in plants).

Explanation: The plant pictured above has grown multiple stolon (runner) plants that are still attached to the parent plant. Since they are genetically identical to the original vegetation, these stolons are considered to be a product of asexual reproduction; once these runners are detached from the parent plant, fragmentation will have occurred.

Lichen

Lichen - Lichen is formed as a result of a mutualistic relationship between a fungus and an algae or cyanobacteria. The fungus provides the cyanobacteria/algae with protection and the algae/cyanobacteria use photosynthesis to provide the fungus with nutrients. Lichen is plant-like in appearance and slowly branches across rocks, walls, and tree bark. Although it doesn't have roots, lichen also feeds off of dead matter as another source of nutrients. Explanation : Lichen is pictured above. Its green pigment helps with photosynthesis and comes from the algae/cyanobacteria. The fungus provides a both a physical body and protection for the algae/cyanobacteria.

Adaptation of an Animal

Adaptation of an Animal - An animal's ultimate goal is survival (avoiding extinction). This requires a species to have techniques for obtaining food and water, successfully reproducing, and protecting themselves from abiotic and biotic conflicts (like predators or harsh climates). An animal adaptation is any physical characteristic or behavioral habit that benefit's an animal's odds of survival. Examples include protective shells, colorful or bland markings, long necks, thick fur, larger ears, and extra bones. Explanation : A turtle is pictured above. This organism has adapted to its environment by developing permanent armor for predator and heat protection. When threatened by carnivores or heat prostration, a turtle hides in its tough shell to avoid confrontation with either of these conflicts. Its shell is also used to camouflage...
