Interpretation and Analysis
Gibberellins are a tetracyclic diterpenoid compound that stimulates the reorganization of cellular organelles and the synthesis of new proteins such as enzymes. GA exerts its influence in two manners, first by increasing the growth potential of the embryo and second by inducing hydrolytic enzymes. Once a plant releases gibberellins, its cells begin a process of elongation. Since plants are composed of single cells stacked on top of one another, this elongation of thousands of individual cells results in the overall growth of the plant.
Usually in germination, the breakdown of starch to glucose in the endosperm begins shortly after the seed is exposed to water. Gibberellins in the seed embryo are believed to signal …show more content…
There is an instant boost in growth rate during the seventh day; the seeds have grown from nothing to approximately 50mm in a span of two days. There isn’t much range (ranging 50 - 75mm) in the measurements meaning that gibberellic acid didn’t have much effect on the seeds.
In figure 2 however, there is a larger range (ranging 50 - 75mm) indicating that the gibberellic acid has had more of an effect on the plants that weren’t exposed to sunlight. The same thing can be said about an instant boost in growth rate, but earlier than the seeds that were exposed to sunlight. The boost in growth rate started around day 4, whereas it started at around day 7 for the seeds exposed to sunlight. While the cause is unknown, it can be said that there might have been errors or inconsistencies in the measurements taken.
After the seventh day the growth seems to be consistent, showing that the gibberellic acid had more of an effect on the plants in two days rather than eleven. In the graph however, there are some drops possibly indicating shrinkage. This does not occur regularly in plants. A reason for this could be instrument resolution (random error). Most instruments that are used for calculation have finite precision making it hard to read small measurements – in this case it was difficult to get exact measurements for the plants because parameters were not defined (i.e where to measure from and to) and the shoots were relatively …show more content…
When taking results, there were very slight differences between the heights of the stems. Growth was seen in the plants, though there were small differences that we could see in the given amount of time. This was consistent across all the soil types. The differences ranged between 1 - 2 mm, which is not enough to come to a solid conclusion. If a graph was made, there would be no noticeable trendline or trends in the data. Instrument resolution was a random error because specific parameters were not defined and the measurement were not constant. For example, sometimes out group would measure to the top of the shoot but not exactly from the bottom. There might have been some measurements, but they were minimal differences for us to notice (human error - faulty
