Radish seed germination experiment

I have conducted an experiment on growing radish seeds. I used 3 petri dishes and added a paper towel lining on the inner bottom of each. I have added acetic acid in one, water in the other and bicarbonate in the other. I placed them in my window sill and tested the pH balance each day. Attached is the chart. It has not been the best weather here with limited sun and we are averaging in the low 50's Fahrenheit everyday. My seeds have not grown or cracked in 7 days. Can you finish of my worksheet given the data presented? I have kept them moist everyday adding 2ml of the appropriate solutions.Your Full Name: Andrew Etan UMUC Biology 102/103 Lab 7: Ecological Interactions INSTRUCTIONS: • • • • On your own and without assistance, complete this Lab 7 Answer Sheet electronically and submit it via the Assignments Folder by the date listed in the Course Schedule (under Syllabus).

Would you expect endangered species to be more frequently generalists or specialists? Explain your answer. Endangered Species would not fit into the group of being a specialist. Generalists are more adaptable to weather and climate changes, whereas specialists can only tolerate small changes to their environment to survive. Therefore, a more specialized animal would more like to be endangered than a generalist. 2. How does temperature affect water availability in an ecosystem? The higher the temperature of the weather the more water that is evaporated into the air. This creates the ground to dry up as in the desert. This makes water very hard to find. On the other hand, if the water is too cold it freezes which also makes it hard to heat up to consume or use for other purposes. 3. Choose a species and describe some adaptations that species developed that allow them to survive in their native habitat. Polar Bear- As we know it the polar bear is on the decline due to global warming. Here are some adaptions that they have implemented to help their survivability. When food is caught they only eat what they need and bury the rest in the snow which helps preserve the food to last longer. The normal meal for a polar bear would be to eat seals but on occasions scientist have found them eating dolphins which is very unusual. Polar Bears also have thick furrs and padded paws to get through the cold. © eScience Labs, LLC 2014 Experiment 1: Effects of pH on Radish Seed Germination Data Tables and Post-Lab Assessment Table 1: pH and Radish Seed Germination Stage/Day Observations Acetic Acid Sodium Bicarbonate Water Initial pH 5 8 7 1 5 8 7 2 5 8 7 3 5 8 7 4 5 8 7 5 4 7 5 6 4 7 5 7 4 7 5 Take a picture of your results.

Compare and construct a line graph based on the data from Table 1 in the space below. Place the day on the x axis, and the number of seeds germinated on the y axis. Be sure to include a title, label the x and y axes, and provide a legend describing which line corresponds to each plate (e.g., blue = acetic acid, green = sodium bicarbonate, etc…). © eScience Labs, LLC 2014 Germination of Radish Seed Number of Seeds Germinated 12 10 8 6 4 2 0 1 2 3 4 5 6 7 8 9 10 Day Acetic Acid Sodium Bicarbonate Water 2. Was there any noticeable effect on the germination rate of the radish seeds as a result of the pH? Compare and contrast the growth rate for the control with the alkaline and acidic solutions. 3. According to your results would you say that the radish has a broad pH tolerance? Why or why not? Use your data to support your answer. © eScience Labs, LLC 2014 4. Knowing that acid rain has a pH of 2 - 3 would you conclude that crop species with a narrow soil pH range are in trouble? Explain why, or why not, using scientific reasoning.
