REACTIVITIES OF SOME ALKYL HALIDES
INTRODUCTION TO ASCLEPIAS CALIFORNICA
The terrestrial plant, Asclepias californica, is the primary food source for Monarch butterflies. It can only germinate and produce seeds if provided with the proper environmental influence. The California milkweed's population is spread out in the southern and coastal areas of California where there are flat lands and grassy slopes. It can also grow up to three feet tall and have clumps consisting of multiple stems that are a couple of feet in width. Unlike the Monarch butterflies, other animals avoid this plant mainly because of its toxic resinoids, alkaloids, and cardiac glycosides. On the contrary, Monarch butterflies ingest the alkaloids contained by this plant for protection from predators such as slugs.
Not only is it used by the Monarch butterflies, but humans as well. Its dried and powdered form can be applied onto skin with a spider bite. And latex contained in the stems and leaves can also make rubber.
Like people, seedlings need to grow up nourished and strong to repopulate. Its necessities include the right temperature, amounts of water, season, surrounding air, amount of sunlight, and soil conditions.
In addition, a fungus known as mycorrhizae will develop within the roots of this plant and eventually undergo symbioses. Fortunately, these mycorrhizal fungi form mutualistic relationships; which will enable the plant to absorb a sufficient amount of water, consume nutrients from the soil, and prevent pathogens from harming the roots. An experiment on the germination and seed production will be conducted with and without the use of the mycorrhizal fungi to determine its level of influence on the Asclepias californica plant's progress. The plants will be raised and nursed in a greenhouse. Overall, the healthy seedlings will be given away for donation to the butterfly gardens located in Orange County.

METHOD:
The seedling project was conducted from October 10th, 2012 to November 26th, 2012. We collected 10

    The experiment was designed to test the hypothesis by planting an increasing number of genus Helianthus (sunflower) seeds in pots to see how they respond to increased density in limited space. Two replicates each of 2, 4, 8, 16, 32, 64, and 128 seeds were planted in similar size pots containing an equal mix of potting soil and perlite. All plants were kept in greenhouse conditions exposed to similar light and temperatures settings and were watered at equivalent intervals. At the end of the time period each pot was evaluated for number of seeds that had germinated as well as number of stems with blooms. Stems and blooms were cut and weighed.…

    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 was continuously watered and adjusted the light bank to help the plant grow more efficiently. After letting the seeds germinate for approximately 14 days, after two or three flowers had opened, a bee stick was used to transfer pollen from one plant to another. Each group then used the bee stick again 2 and 4 days after the initial pollination. Once all of the transferring was complete, each unopened bud on the plants were pinched off. Approximately 21 days after pollination, the seeds were ready to be harvested. Each quad was removed from the watering tray and allowed to dry for 5 days. After the plants were dry, each group removed the dry seedpods from the plant. We then removed the seeds from the pod. To start the germination process, a moistened piece of filter paper was placed into a petri dish. 40 seeds were neatly placed into each petri dish until there were no seeds remaining. Once all the seeds were placed in the petri dish, the petri dishes were placed in a plastic bag and set to germinate for approximately 48 to 96 hours in the window at room temperatures.…

    On February 20, we filled two pots halfway with soil then added two MPK 10, 10, 10 fertilizer balls to both the pots, covering the soil with water making sure it was damp. We then filled the rest of the pot with more soil and sprinkled some water. Next we poked two holes that were spaced out evenly for the low density and ten holes for the high density. After that, we placed a thin layer of soil and water on the seeds and made sure they did not drown as described in the laboratory manual (Asbury, 2008). We placed them in an open container where the pots were no closer than six to eight cm from the…

    Radish Seeds

    A seed is a fertilized ovule that contains an embryo and transforms it into a new plant through the process of germination. Seeds remain inactive until conditions are right for germination. All seeds need water, oxygen, and proper temperature in order to germinate. However, some seeds require full light or darkness to germinate. According to Holm (1996) seeds have chemical inhibitors that prevent germination. A seed will not grow unless those inhibitors are destroyed by things like temperature changes, moisture, and sunlight. These conditions combine in infinite ways, making each plant's germination needs different. The first sign of germination is when the seed absorbs the water. Water and oxygen are taken in through the seed coat causing the embryo's cells to enlarge. The seed coat breaks open and a root emerges first, followed by the shoot or plumule that contains the leaves and stem (Campbell 2004).…

    In the natural world, plants are in constant strain of exploitation and competition. Through the evolutionary process, plants have developed many ways to help cope with various environmental stresses. Some plants overcome environmental strain by growing taller or deeper to extract as many resources as possible. Others resort to numbers and try to overwhelm their predators and competitors by population size. However, possibly the most interesting method many plants take is the use of chemicals to kill or inhibit predatory herbivores and competing plants. Plants that resort to this method of defense are known as allelopathic and the chemicals used by these plants are called secondary metabolites.…

    White Bird-of-Paradise is most often planted for its large, banana-like leaves and upright, clumping stalks which give an exotic feel to the landscape (Fig. 1). Plants can reach 20 to 30 feet in height with a spread of 10 feet though they are often seen much smaller. The five to eight-foot-long, cold-tender leaves are arranged in a fanlike display from the erect trunks and appear much like Traveler’s-Tree. The lower trunk becomes clear of leaves and exposed as the older leaves drop off. Leaves rip along the veins as they are blown by strong winds.…

    California is a state of enormous diversity. From the coast to the mountains and the forests to the deserts, California is full of a wide array of plant life. California is the third largest state in the United States and thus has a major variation in climate resulting in the many plants found. Not only are there many plants found here, but many of those plants cannot be found anywhere else. There are also many nonnative plants that have become a part of the scenery in California. The best way to understand the state’s vegetation is to first understand the floristic provinces.…

    The plants used in this experiment are called Wisconsin fast plants, due to their extremely short life cycle. In just 40 days, the plants germinate, grow, flower, and die, which makes them convenient to study in classroom experiments. They are members of the crucifer family and are related to other plants like broccoli and cabbage. In this experiment, 8 fast plant seeds were planted in a self-constructed bottle-growing system, and they were left to grow for 7-14 days. The Net Primary Productivity, or the amount of energy captured and stored by the fast plants, was calculated along with the flow of energy from the plants to cabbage white butterflies. These organisms are members of the Pieris Rapae family, and they feed on fast plants. The goal of this experiment is to observe the flow of energy in an ecosystem as it is transferred from the producers (Wisconsin fast plants), to primary consumers (butterfly larvae). This energy was kept track of by making sure all energy gained and lost by each organism was measured.…
