Experiment: The Effect Of Sunlight On Vigna Radiata

The purpose of this experiment was to investigate the effects of light intensity on the rate of photosynthesis in a Moneywort plant. By observing the plant in distilled water mixed with sodium bicarbonate, different light bulbs were targeted onto the plant. The measurement of the amount of bubbles present on the plant during the trial of the experiment enabled us to identify the comparisons between the activity of the light and the process of photosynthesis.

The first lab was conducted to analyze how germination affects the rate of cellular respiration in lima beans compared to dormant seeds. In order to

The hypothesis behind this experiment is that the Gibberellic acid has a positive growth effect on the plant and causes it grow larger in height.

The results observed do not correspond with the outcome predicted by the hypothesis. Despite the nature of the subjects of the experiments, no substantial growth was observed. Only one seed of the 36 planted germinated, and it could only survive for a period of a week. The one seed that germinated reach a height of 1.2 cm. Table 1 presents the average growth observed in each quad. Each quad had a total of 12 seeds. No seeds were removed during the course of the experiment.

The purpose of this lab was to investigate and observe the effects of organic vs. synthetic fertilizers on plant growth by planting lima beans with added amounts of fertilizers, and to see how does adding different nutrients to the soil affect the growth of the lima bean? A significant difference was examined between the plants that contained manure and miracle growth, unfortunately the plant with no additional fertilizers (Plant #3) did not show any growth. The plant that grew the most was the one that contained manure, to an extent the one that grew the most in a short period of time was the one that contained miracle growth, as shown in figure I. The hypothesis explaining if the Lima Bean plant contains synthetic nutrients in the soil then

To discover how lima bean germination was affected by the use of other liquids in the place of water.

At the rate of irradiance was at 0 μmol quanta/m2/s, the results from Figure 1 show that the rate of dark respiration for shade plants was smaller than the rate of dark respiration for the sun plants of the soy plant species. The actual value obtained for the low light plant was -0.6023 μmol CO2/m2/s, which was extrapolated from the point of the graph when x=0. This value was very similar to the linear equation extrapolated from 0 to 400 irradiance μmol CO2/m2/s, y=0.0104x-0.606, where y=-0.606. The actual value of the rate of dark respiration of sun plants was -1.7312, which was slightly deviation from the rate of photorespiration calculated from the linear equation, y=0.0104x-1.4838, where y=-1.4838. From looking at this data, sun plants had a greater rate of respiration than shape plants, indicating that the transition of shade plant leaves respiring to the mode of generating photosynthesis, is faster than for sun plant

Four cups of equal size were filled with one cup of garden soil. Lima beans were planted at an equal depth (one inch as instructed on the bag). Every day, for 33 days, each plant received one half tablespoon of the specified liquid. Beans one and two got one half tablespoon of water each,

First, before starting my experiment I did some research on the growth of lima beans, so that I could start the base of the project. According to research done at the University of

For the purpose of this experiment, we used mung beans. The goal was to prove that female bean beetles prefer full sized mung beans over half sized mung beans. From this experiment we hoped to observe bean beetles, and gain more knowledge on their bean preferences. This experiment is designed in a way that the female bean beetles must choose between the two sizes.

Have you ever wondered if music really affects the growth rate of plats, or if it even has anything to do with growth rate? In this experiment, we will grow two separate plants, one with classical music, and another with no music at all. The soil used will be the same in order for the outcome to be unbiased. The bean seed will be grown over a period of 6 weeks. Bean seeds are an easy plant to grow, and only require sunlight, warmth, soil and water. That is why we chose to grow it. The characteristics of the bean plant made it an easy pick for us. Bean seeds have similar growth patterns to other plants, such as corn. In fact, they are so easy to find and grow, that even a simple bean found in the grocery store can be fully

There are many ways to obtain seeds to grow flowers in the springtime, but not all seeds were created equal. Sunflower seeds, for example, can be bought at a garden store in a packet for $1.5 dollars per 6 gram packet, but they can also be found in bird seed for $3.53 dollars per 10 pounds. This experiment intends to find if the germination of a store bought packet of sunflower seeds matches the germination rate of sunflower seeds obtained from a bag of bird seed. While both seeds will germinate, it is believed that the bird seed will not be as robust in growth as the garden seed, due to the fact that the garden seed is made to be grown, while the bird seed is made for consumption.

Helen's Recipes, Inner Engineering, Natural Vita, and Joyous Health all started with taking their mung beans and putting them in water. The temperature of the water was unanimously agreed upon to be warm but not hot or the beans would not sprout properly. Also, the beans must be moved away from direct sunlight or put in a dark place such as Helen's Recipes did. Another point upon which all four videos agreed is that it takes a while for the beans to sprout. While one waited for 8 hours and another waited about 5 days, one must wait till the beans are perfect to them.

The effects of light intensity and light wavelength on photosynthesis was observed in two different experiments and closer study of different pigments in spinach was observed. For the experiment where the effects of light was observed, it was found that a light intensity of 30 cm, wavelengths of blue and red lights show the greatest photosynthetic activity. The different pigments present is spinach were also observed and it was noted that though chlorophyll is the most abundant in plants, there are other pigments present as well.
