The Effect Of Acid Concentration On Plant Plants And...

Introduction Gibberellic Acid is a naturally occurring plant growth hormone that belongs to the gibberellin group (Gupta and Chakrabarty, 2013). Gibberellins are responsible for stem growth in plants and regulate the synthesis of proteins. Gibberellic acid is a by-product of the Gibberella Fujikuroi fungi which has the effect of causing developing rice plants’ stems to grow in such an expeditious manner that the plant collapses (John M. Riley, 1987). The experiment’s variables include the independent variable, which is the concentration of gibberellic acid that is used to soak the seeds, and the time period of germination, as well as the dependant variable, which is the number of seeds that germinate. The control used to compare seed germination and in this situation is the sample with a gibberellic acid concentration of 0 ppm. Constants in the experiment include factors affecting seed germination such as constant temperatures where each sample receives the same temperature and in the case of variation the same amount of variation, quantity of moisture where the same amount of gibberellic acid is added to each bag corresponding to the concentration, the samples should also receive the same conditions of light, have the same sowing density, and number of seeds per square centimetre. The aim of this practical is to investigate the effects of gibberellic acid on the germination rates of two plant species. It was hypothesised from the above information that higherShow MoreRelatedPlant Hormones1654 Words   |  7 PagesPlant hormones are specialized chemical substances produced by plants. They are the main internal factors controlling growth and development. Hormones are produced in one part of a plant and transported to others, where they are effective in very small amounts. Depending on the target tissue, a given hormone may have different effects. Plant hormones play an integral role in controlling the growth and development of plants.

Detail study shows that cell membranes consist of 4 major components:1) Lipid bilayer, 2) Transmembrane proteins or Integral membrane proteins, 3) Interior protein network and 4) Cell surface markers. The main fabric of the membrane consists of amphiphilic phospholipid molecules. Integral proteins, the second major component, are integrated completely into the membrane with theirRead MorePlant Hormones : Chemical Substances2303 Words   |  10 PagesPlant hormones otherwise known as phytohormones are chemical substances synthesized within the cell for use in regulation, cell to cell communication, and growth and development of the plant. These hormones are usually transported to a different cell to elicit a response. However, there are some which are able to act within the cell in which they were synthesized. They are synthesized in low concentrations and they are small in size for ease of transportation through the cell wall.
