The Genetics of Fast Plants Kristin Phillips Dr. Orlando April 4‚ 2014 Abstract The experiment that was being completed was the genetics of plants using Fast Plants. The purpose of this project was to understand Mendel’s concept of a Dihybrid by performing similar crosses and calculated the phenotypes that are displayed. This project was conducted over many weeks by planting F1 seed and waiting for them to grow then cross-pollinating the F1 plants to produce the F2 seeds. Next students

concluded that indeed sawdust can serve as an alternative to soil since it can support plant growth. INTRODUCTION Background of the Study All plants grow on an organic material called a medium. This serves as a base for plants and is where several organisms are attached to and grow. Plants are geotropic that is why their roots grow towards the ground. Soil is commonly used as a medium in growing plants. It is rich in minerals that aid in the growth and development of vegetation. There are

Fast Plants By: Kinser Haselhuhn Biology 111 Section Y Professor Brittingham 4/19/13 Abstract: Introduction: Materials and Methods: To begin the fast plants experiment‚ each group received the F1 generation seeds for their designated phenotypes. After receiving the seeds‚ the seeds were then planted into Styrofoam “quads” allowing the seeds to germinate. The seeds were then allowed to grow under a fluorescent light bank for 5 weeks. Throughout the growing of the seeds‚ each plant

Inheritance System of anthocyanin pigments in Brassica rapa. Introduction The observations of Brassica rapa in class revealed a variation in color. Brassica rapa‚ also called fast plants‚ was studied because as their name suggests‚ they are able to complete a lifecycle in a short period of time. (www.fastplants.org) The color variations we observed among the plants were that some had green stalks while others were purple. The pigment which gives plants their color is called anthocyanin.

ABSTRACT: By exposing Brassica rapa seedlings to UV-C light‚ the effect of the growth and development of Brassica rapa seedlings was tested. The experimental group of Brassica rapa seedlings was exposed to 254 nm UV-C light for thirty seconds after one week of growth. Throughout the duration of one month‚ the height‚ number of leaves and stem diameter were measured sporadically. After one month‚ the biomass of the seedlings was recorded. A starch analysis test was also performed. According to the

Examining the activity rate using DCIP and a spectrophotometer of succinate dehydrogenase isolated from Brassica oleracea mitochondria via mechanical disruption and differential centrifugation Introduction Mitochondria are important cellular organelles located in the cytosol of cells and is believed to have originated through an endosymbiotic relationship. The unique double layered membrane structure is responsible for the production of the primary energy currency of the cell; adenosine triphosphate

Each week the the the stems of the plant well be measure‚ the leaves will be counted and the information will be kept in a log. The hypothesis stated that crushed fertilizer would lead to more leave been produced

traspecific competition in growth of Brassica rapa in low and high-density treatments Rimel‚ Stuart F (thursday 11am) Abstract Intraspecific competition was examined on Brassica rapa‚ a species of fast growing mustard. Intraspecific competition is competition between individuals of same species living in the same population and competing for a limiting resource (Aspbury and Gabor‚ 2007). Brassica rapa was grown in a Laboratory in 10.16 cm pots and grouped in treatments of low density –

The plants were then transplanted to the soil mixtures after 15 days of germination. The heights of the plants were obtained every week. After the span 45 days (since the day of germination)‚ the plants were harvested and the heights and weight were taken. Results show that there is a significant difference between the mixtures made.
