Brassica rapa, better known as the Brassica campestris, which is part of the mustard family. It is originated from Europe, but is now found all around the world (Courteau, 2012). This plant can grow anywhere between 30 to 120 centimeters tall. The growth of a plant is controlled by the hormone of the plant. The hormone will send a chemical signal to the plant which allows it to grow. An example of a plant’s hormone is called gibberellin. Gibberellin (GA) is responsible for the growth and the development of the plants and it’s actually an acid. The role of the (GA) is the process of stem elongation and germination. The stem elongation will stack the cells on top of each other causing the plant to grow. In this experiment, two different strains …show more content…
The other side of the quad will have the rosette side on it. At the bottom of the quad, the tip of the wicks was placed on each cell. That will allow the water to soak up into the soil. After the wick is placed in half way then half way of the soil was filled. A little amount of water was added to moisten the soil. 3 fertilizer pellets were added after then the rest of the cell was filled with soil. The instructor will add the seeds of the wild type and rosette in the soil. The quad was later placed in a watering box. The cells that wat label with the (GA) will have a drop of the (GA) treatment. After the first week of the experiment, all the plants were removed, but one with a scissor. That will allow the plant to be properly measured without other plants being in the way. For the next four weeks, the same steps of measuring, added water or (GA) treatment will be repeated. The plant will be measured in millimeter. When the plant would grow taller than its best to add a stick to help the plant stand straight and make it easier to measure. Each week the measurement will be written …show more content…
The (GA) in the wild type is growing slower in height than the wild type that has the control. Until after the (GA) passes the third week. Figure 2 in this graph has rosette plant and the water is increasing at an even pace. The (GA) treatment in the first week is similar to the rosette with water. After the second week, its height is twice as much more than the water.
Discussion
The hypothesis for the wild type was a reject in some sense. The water height was greater than the (GA) treatment for three out of the four weeks. The last week is where is was greater in height at 4 mm more than the water. The wild type control at the last week average is 79 mm and the (GA) is 83 mm. The second hypothesis is accepted because it has increase twice as much as the water after the second week. In the last week, the water has reach the height of 33 mm and the (GA) ha reach twice as much at the height of 63 mm. the reason why wild type is less effective than the rosette is because the rosette is a phenotype plant that contain less amount of gibberellin acid. That will allow it to grow twice as more as the wild type; which already has the
