33,34,35... long day plant, predation, bilateral symetry

This tasty looking potato is a splendid example of a long day plant(big idea 2#29). This term refers to a unit of measurement of how much time a plant spends in the cycles of light and dark. plants can sense the time shifts of these periods and uses them to detect the changes of the seasons, most plants will blossom regardless of how long the dark-cycle is as long as they recieve enough light. Long day plants bloom as soon as they reach their critical ploto period, explaining why many plants bloom in spring when the day begins to lengthen.
This hole is actually an animal burrow,deducible by the mound of soil outside and the way most leaves have been cleared from the enterence. A reason for a burrow like this is to defend against the elements as well as predation(big idea 4#18). This is when one organism feeds on and usually kills another in order to attain nutrients from it. It is what forms trophic levels and a food chain in every ecosystem. All hetrotrophs are some sort of predators, eating another organism for food.
 
 This highly attractive house plant in my living room demonstrates bilateral symetry(big idea 1 #12). This term refers to anything in nature that is symetrical across a line. It is similar to math equations and graphs in which the inverse is found;identical across the line of symetry. To me, bilateral symetry is geometricly appealing and i would recomend the offspring of this plant to any who agree(+shipping and handling). This is common in animals to help them balance.
