Seed Germination Lab
Introduction/ Background Information Seed germination is the process by which a plant sprouts from a seed. Biology Discussion displayed the different steps of seed germination, and the first stage of seed germination is imbibition, which is when the seed absorbs water. This causes swelling and thus resulting in the outer coat of the seed to break and then, it will form a root. The next step in seed germination is respiration. This is when the seed takes in water and oxygen and begins to breathe and thrive (Process of). This is vital so that the plant can live and take in carbon dioxide and produce oxygen. According to NCS Pearson, many things can affect the germination period, such as temperature, soil, and light (Factors). However, does the age of the seed affect the germination period? In this experiment, a total of six pots were used, three had seeds that were six years old and three had seeds that were only one year old, and throughout the course of fifteen days, the plants were closely monitored to determine how quickly and how many seeds grew. The purpose of this lab is to determine if the age of a seed affects the germination rate. The variables that will affect this are the age of the …show more content…
Since the data will be checked every day around the same time, the data will be constant, which allows validity and reliability to the experiment. Also, there would need to be a large enough sample to have a statistical significance to determine if the age of a seed actually affects the germination period. Lastly, the pots would need to be bigger and less seeds would be put into the pots. This would help the seeds grow at a proper rate because they would not be competing for resources.
Conclusion The data displayed that more seeds in the new pots germinated much quicker than the pots in the old pot; therefore, the age of a seed does affect the germination

The difference there is a whopping 8.6 centimeters. Not only that, but the seeds have a coating and when it separates from the seed that signals that the seed is beginning to germinate. After the 8 days, the seeds with only water were all separated from their covering, while the 4% solution only had 2 beginning to peel. Finally, we concluded that because of osmosis, the seeds with more “Miracle Gro” were bound to grow the least.

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.

915 Words | 4 PagesHuman error played a factor because it was not made sure that air was trapped in each bag. In the class data the amount of seeds germinated on day three was higher than the amount of seeds germinated on day four. This is not possible as the amount of seeds germinated cannot decrease, rather they should stay the same or increase. A seed cannot go from being germinated to not being germinated. This could have occurred from miscounting or not accurately counting the number of seeds germinated.

Biology: Photosynthesis And Respiration
593 Words | 3 PagesAs 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?

644 Words | 3 PagesThe elementals surrounding the seed have issues even looking at it. Simply catching sight of it causes their very consciousness pain and anguish leading them to flee... and flee far. By nature of an elemental, they are conscious embodiments of forces in the universe and cannot die so they know no fear. They are at one with creation and yet... this is something else, separate from creation and it strikes them with true terror they have never felt before.
Radish Seeds Lab Report
360 Words | 2 PagesIn this experiment, scientists, Emily Yau and Mona Howell, conducted an experiment that tested how acidity and radiation affects germination of radish seeds. We had hypothesized the seeds that microwave for 5, 10, and some of the 15 second seeds will grow. The radish seeds in the 1 and 2 teaspoons will sprout. We should accept our hypothesis because in the most part, it was correct. Although most of our data supports our hypothesis, some of our data contradicts our hypothesis.
Yeast Fermentation Lab
529 Words | 3 PagesTitle: How Ph Levels Affected the Fermentation of Beer Hypothesis: The beer will be left with more sugar deposit as the Ph levels increase because alpha/beta -amylase will no longer function. Predictions: Alcohol Percentage Analysis for the Control and the Experimental During this experiment, the pH level was increased, therefore Alpha-Amylase was favored. Due to the nature of Alpha-Amylase cutting randomly through a large carbohydrate molecule, it leaves bigger sugars in the flask, which cannot be digested by yeast. Due to this, less reactions should occur in the experimental, therefore leading to a lower percentage of alcohol production, compared to the control.
How Does Acid Rain Affect Plant Growth
1186 Words | 5 PagesIntroduction: In this task I will be researching the effect that acid rain has on the rate of plant growth. Acid rain is any type of precipitation with a high pH, with high levels of nitric acids. The reason why I had chosen this topic was because acid rain seems to have a great effect on the effect of plant growth, and plants play a very important role in our ecosystem. Acid rain is a major problem in our environment when we are not able to neutralize the acidity.

This also relates to the ability to pick up the beans, rough would be harder and take longer to pick up. This is show as the two of the three groups of smooth beans went extinct, while the two rough sets of beans finished with the densest populations. Another aspect that affected the survival of the beans was the color of the
Respirometer Experiment
1436 Words | 6 PagesThis suggests that as the temperature increased cellular respiration increased until it reached an optimal level somewhere between 400C to 600C. (Text book ref) BIOLOGICAL UNCERTAINITIES I bought the seeds two days before the experiment attempting to purchase seeds of the same age with almost identical sizes. However, even though I attempted to control the biological factors, some seeds germinated faster and at a better rate than others. The seeds that germinated better would also consequently give a higher rate of cellular respiration than the rest. I tried to correct this by choosing germinated seeds of almost similar visible size and also added in each respirometer the amount of dry/fresh seeds and beads that would equal to the total volume of germinating seeds and water in a graduated
