Register to read the introduction… During the early stages of growth the seedling relies on the food storage as it’s main source of nutrients until it is large enough for its own leaves to begin making food through photosynthesis. The seedling’s roots burry down into the soil in order to anchor the new plant into its new source of water and minerals from the soil (Singh-Cudy 61). As soon as the seed begins to germinate we can identify if a plant is a monocot or a dicot. A monocot has only one seed leaf, which is usually long and thin, whereas a dicot has two seed leafs (“Monocots verses Dicots Explained”). For the purposes of this experiment we need to identify soybeans as dicots and corn as …show more content…
We separated our eight pots into four groups consisting of an unknown, known, control, and extra treatment group. Over the course of two weeks our plants were placed in a greenhouse where they were given time and the proper resources to germinate and begin growth. Our plants were then treated accordingly to the label that they were given in the beginning of our experiment. In our experiment our plant growth was manipulated using a known and unknown herbicide, as well as an extra treatment. After the plants were allowed two weeks of growth the greenhouse staff administered two different herbicides accordingly followed by our group’s administration of the extra treatment. It was then our responsibility to make observations of our plants and work to discover the identity of our unknown herbicide.

The known herbicide applied was Glyphosate, otherwise commercially referred to as Round Up. Round Up acts on the plant by prohibiting protein synthesis of tyrosine, phenylalanine, and tryptophan. The herbicide affects strictly dicotyledons. We hypothesized that if our known plants were indeed treated with the herbicide Round Up, then our treated soybean plants would die (“Agricultural Herbicides”). We predicted that the leaves of the treated soybean plants would show signs of browning and wilting, as well as death in the roots of the
