Germination Lab

The experiment was begun by obtaining four 8 oz. Styrofoam cups and punching a hole through the bottom of them. This hole was for water entry or excess water drainage. Moistened soil was packed to the 1/2 full line in the cup along with 3 fertilizer pellets The cups were labeled the following: Rosette-H20, Rosette-GA, Wild-Type-H2O, and Wild-type- GA.(Handout 1) A small wooden applicator stick was obtained a moistened at the tip with water from the petri dish labeled ‘water.’ This was to be able to attract the seed to the applicator in order to place the seed from its original container into

For my seed experiment I had decided to see what the effect of sprinkling salt on a radish seed would be. So for my control group I had set six (6) cherry radish seeds in between a damp paper towel and then closed it within a Ziploc bag. For my experimental I had set it up the exact same way as the control group but I would sprinkle salt on top of seeds before I zipped up the baggie. I sprinkled the salt on the experimental seeds and dampened the paper towel once every day. Each bag was stored in the light and at room temperature (~70° F.)

Our data recorded shows that the germinating peas did consume more oxygen than the non-germinating or the glass beads alone and that the cooler temperature did slow down the consumption of oxygen in the germinating peas. In both water baths the atmospheric pressure seemed to increase causing our reading to raise in our glass beads and non-germinating peas. This direct relationship in reading leads us to believe that the oxygen consumption in the non-germinating peas was minimal if any at all.

The purpose of this experiment is to observe the effects of Sodium Chloride (NaCl) on the germination rate of Wisconsin Fast Plants.

When planting a seed, many factors allow the seed to grow and become a plant. To sprout from the ground, and to survive, seeds need water, air, and a certain temperature. Seeds can get water, oxygen, and sun by being placed at the proper planting depth. Planting depth is the depth at which a seed is placed in the soil. If a seed is exposed to these important needs, it goes through a process called germination. According to the Wise Geek article, “What is Germination?”, “Germination is a process in which a seed or spore awakens from dormancy and starts to sprout.” (“What is Germination?”).

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.

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 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.

In generalization, there are a multitude of factors that could potentially influence the germination of a radish seed. This lab thoroughly exhibits the effect of water amounts on the germination of a radish seed. There is indeed an in-depth science behind the projected results, and overall of the effects water has on the germination of radish seeds, and the growth of plants in particular. Radishes themselves are moisture-loving plants; therefore, it is significant that they receive an adequate amount of water, allowing the soil to be moist, but not overly saturated (Biology Coach, 2015). In general, water is significant for the health of a plant in the way it transports important nutrients throughout the plant. From this point, nutrients are drawn from the soil and used by the plant. Seed germination itself is defined as the process where the seed sprout for growing, and future development into a plant. In order to germinate, the seed must have its essential needs met until it is capable of doing so: water, temperature, and sun. Therefore, during its early stages of growth, the seed will rely upon the food supplies stores within it, until it is large enough for its own leaves to begin making food through photosynthesis (Biology of Plants, 2016). Initially, the process of germination begins with the absorption of water y there seed, therefore, this absorption of water then activates an enzyme that increases

Therefore, I was correct in my hypothesis that dark will have an effect on the germination of radish seeds. Also, I was very close in predicting that the seeds grown in the light will germinate twice as much as the seeds grown in the dark; the control seeds grew a little less than double the size of the experimental seeds. Ultimately, my experiment proved that light is a very important factor in the growth of any plant. However, I’ve learned that seeds grown in the dark will germinate, though slowly, as

The second step of the experiment was to soak the seeds in water overnight. This action was made to prepare the seeds for germination and making them more softer and less rigid. The seeds were placed in a bowl and were covered by tin foil. It was set up on the refrigerator to minimize any outside interference that may come to it. After a full night of absorbing the water, the seeds were ready to start the next stage.

The purpose of this experiment was to test how the variation of pH values affects the germination of a genetically enhanced seed. The experiment was conducted by using three different liquids: vinegar, baking soda + vinegar, and water. Seeds were placed in petri dishes containing the liquid and the growth was measured (mm) weekly with a ruler. Trends include the large amount of growth from the H2O seeds and little to no growth from the vinegar seeds. Uncertainty stemmed from the change in weather and the ruler.

The aim of this investigation is to better understand and further determine the effect of soil moisture contents on the growth (height) of Raphanus sativus (radish seeds).

This study was done to look at the effects of fertilisers and identify which fertiliser produced the fastest results. Four types of fertilisers were used over a four-week period and the findings were that inorganic fertilisers enhanced seed germination rates.
