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 of the same species of plant will be tested with gibberellin and without it to see the rate at which the height of the plant increases. Wild-type and rosette will be used and the difference between them is that the rosette is a dwarf version and the wild-type is a normal growing version. Wild-type will grow with water, but if gibberellin is added then its height will increase much faster than with water only. Rosette will grow with water but if gibberellin is added then it …show more content…
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
