Douglas-fir and red alder have seeds that use wings, signifying the use of the wind as a method of seed dispersal. Both trees have seeds than are covered in a seed coat and have nutrient reserves. Gymnosperms, however, have a large megagametophye, which is the haploid nutritional tissue. Angiosperms typically have a smaller megagametophye, that later develops into an endosperm (red alder, however, does not have an endosperm). When seeds germinate, general 4 steps usually occur first: 1) Imbibition, when seeds swells with water and the seed coat ruptures 2) Metabolism increases.
We then obsevered the two slides for number of cells as well as for food vacuoles inside a cell using a microscope at times of 0,5,10,20, and 30 minutes. Results The following graphs show the results of this experiment. The tetrahymena sample that was introduced to concentrated tobacco had a lower cell/vacuole ratio than the tetrahymena sample that was not exposed to
In his book Seedfols by Paul Fleischman writes about a charter about Virgil. Virgil’s dad seems to selfless, because he always worries about his sun Virgil. Virgil’s father is a taxi driver, and askes people what is a crop that will make you earn a lot of money. Virgil and his dad planted baby lettuce. The money that they would have made from selling the crops would have goon towards buying a bike to Virgil.
Discussion Board for Radish Seed Germination Experiment Anna Jean Discussion The number of radish seeds germinated was most successful in a solution with a 0% concentration of Miracle-Gro, as all ten seeds germinated on average over a 5-day period. This is opposed to when the radish seeds were put in a higher concentration of Miracle-Gro, then the number of germinations decreased (Figure 2). The application of Miracle-Gro has proven ineffective in promoting the germination of radish seeds in this experiment. Although Miracle-Gro contains nutrients like nitrogen, phosphorus, and potassium, which all assist with plant growth, it seems to have the opposite effect when germinating the radish seeds.
As stated in the background of the lab, "seeds are considered to be in a period of dormancy, where they metabolize stored energy at a very slow rate while the seed is still considered alive" (Hands On Labs). During germination, the developing plant embryo uses the stored food supply in the seed for cellular energy and growth. Thus, cellular respiration is taking place as the seeds grow. Without water the seeds cannot begin germinating thus the seeds in test tube N did not undergo photosynthesis(Hands On Labs). B. Were the seeds in the “G” tube undergoing both photosynthesis and respiration, only photosynthesis, or only respiration?
apart. After planting and gently covering the seeds, the soil was moistened with 1 oz. of distilled water. We printed a 27 cm ruler and taped it to the inside of each cup for accurate measuring. The cups were placed in a window sill with sufficient access to sunlight.
Alaina Couch Effect of Salinity on Seed Germination and Plant Growth During this experiment, we tested the effects of soil salinity on the germination and growth of Wisconsin Fast Plants. Wisconsin Fast Plants, also called Brassica rapa, are closely related to brussel’s sprouts, kale, cauliflower and other vegetables of the Brassica genus. These plants were bred by Dr. Paul Williams and under favorable conditions, they have the ability to complete their entire life-cycle in just 28 short days (Williams, 1997, p. 1). Sodium Chloride, also known as salt, is a naturally occurring compound on planet Earth.
1. Coriander Seeds: Whole coriander seeds add bursts of citrusy, herbal flavor to your food. Coriander seeds are popular the world over and a staple in many sauces and marinades. Use a mortar and pestle or spice mill to create coriander ground or add the whole seeds to your sauce for a bolder flavor. For an Indian-style curry, simmer cream, stewed tomatoes, coriander seeds, curry powder, and garam masala with marinated chicken and serve over steamed rice.
For any seeds that did not germinate, the seed length was measured and used towards the data. The plant heights were put into a data table and a mean was found for each level of I.V. for further data analysis. Then, all of the steps from placing the seeds into the microwave to adding the plant lengths together for the final data, including those two steps, were repeated four more times for a total of five repeated trials. Next, all of the steps from placing the seeds into the microwave through the step preceding this one, including those two steps, were repeated for a total of five repeated trials for all remaining levels of I.V., excluding the warm water level(100W for zero seconds, 500W for 30 seconds, 900W for 30 seconds). Finally, all of the plant lengths, including those that did not germinate, were added together for the final
Bean Sprouts Project One of my most memorable experiences of soil was when I was in Sixth grade. At the end of Fifth grade, I flew from Hong Kong to South Korea along with my family. In the first couple of weeks of school, I struggled to speak Korean and adapt to the new culture. Fortunately, I soon saw the chance to change this situation: the Science II Bean Sprouts project. The Bean Sprouts project was simple.
Having different types of seeds grown by the class then the class can tell if radation really does help plants. The hypothesis for this experiment of how will radiation affect seed growth is “ If plant seeds are exposed to microwave radiation then the growing process will increase.” My seeds(zucchini seeds)will be placed in three cells and cell number one will not be microwaved at all. Although cell number two and three will be microwaved.
For all the section in total here were about 5,995 seeds that were not germinated and the question is, why? We can see a pattern that only about 60- 70% of the seeds were actually germinated, so what affects germination. Germination can be affected by temperature, moisture/water, and soil use. If the temperature is extremely high or low then that is not ideal for the fast plants. When it comes to the soil use and fertilizer, due to the absence of the first lab, I am not sure if the previous TA measured a specific amount of fertilizer nor a specific soil for this
Germinal is the story about the miners' strike against the mining company during the period of industrialization. As the technologies developed, people needed more workers so the number of them highly increased. With the large amount people, some labor issues were emerged. Inhuman working and living conditions, lack of proper welfare system, low income, high intensity of the labor and the long work hours exhausted the workers. The workers had to unite into the labor union because they couldn't solve those big problems individually.
The sunflower seed is the seed of the sunflower (Helianthus annuus). The methanol extract of seeds of Helianthus annuus were screened for analgesic activity in mice model to systematically explore the medicinal values of the plant. Acetic acid induced writhing and hot plate methods were used to confirm the central and peripheral analgesic action. The extract at dose 100mg/kg and 200mg/kg showed attenuated writhing inhibition at 50.35% and 57.85% in case of acetic acid-induced writhing test which showed significant analgesic activity (p< 0.05). In the hot plate method increase (p < 0.05) of latency period was also observed in comparison to standard aspirin.
The difference between 1.54% and 2.31% solute (sucrose) concentrations is very small, 0.63, compared to the difference between 0.00% to 1.54% solute (sucrose) concentrations. The mean height of the common wheat increases from 2.31% to 3.08% by 0.12.The mean height of the common wheat starts to decrease by 1.91 between 3.08% to 3.85% solute (sucrose) concentrations, getting closer to the decrease between 0.00% to 1.54% solute (sucrose) concentrations. The mean height of the common wheat tends to decrease steadily in the Graph 1.1 and it can be explained by osmosis. In the experiment there was concentrated (sucrose) solution added to the soil, which caused a low concentration outside the plant cell and made the water from the seeds (high concentration) to move to an area of lower concentration outside the plant cell. This made the common wheat seeds lose water, which is important in photosynthesis and growing, and therefore slowed down their
