The rate of germination didn’t really vary between the number of paper towels throughout the experiment. Most of the seeds had germinated in the paper towels. The one outlier that was strange was the one paper towels. Only 14 of the 15 seeds germinated in that group. The difference that we could observation was the healthiness of the plants. IV. Conclusion Paragraph 1 Recap (Evidence): The purpose of our lab was to see if the amount paper towels would affect the germination of the seeds. My

Question/Purpose: The Question or Purpose of our lab is to answer the question “How is the germination of a seed affected by sunlight?” Experimental Hypothesis: We believe these results will occur. 1. The seeds that are water deprived (1 mL of H2O a day) will not grow very well due to a lack of water which is important in photosynthesis and also lacks nutrients. The seeds may also die off due to a lack of water. 2. The seeds that are have a proper amount of water (10 mL of

Seeds require moisture to germinate. By presoaking a seed‚ it strips of the protective layer of the seed and speeds up the rate of germination. But the longer someone presoaks a seed‚ the greater the chance it has to rot. When presoaking seeds‚ one should avoid planting them in dry ground due to the risk of the moisture being taken out of the seeds instead of sticking with it to germinate‚ leaving the seed back to its original state. purpose - There are many factors that affect germination‚ however

My inference of the B. Rapa seeds was that they would most effectively react to the peat moss because of the high concentration of water. I reject my hypothesis on the basis that peat moss had the least positive productivity in the experiment. My results show that peat moss was the most unsuccessful in assisting the growth of each plant. Pods 1‚ 3‚ and 4 never broke through the soil‚ and remained at a depressing 0 centimeters the entire length of the experiment. The 2nd pod did grow slightly. It

Two experiments were performed to investigate the effects of temperature on the growth rate pine seedlings. Experiment 1 A batch of 60 pine seedlings (Batch I) was grown in a greenhouse under controlled temperatures. Ten plants were grown at each of six temperatures from 50 C to 300 C. These plants remained at their original temperatures 24 hours each day for two weeks. All other conditions were the same for all seedlings. The growth rates are shown in Table 1. Table 1.

and identification of Bacterial isolates An enrichment culture technique was used for the isolation of bacteria responsible for biodegradation of phorate in soil. Screening of these bacterial species for phorate degradation in liquid cultures in our previous study (Jariyal et al.‚ 2014)‚ resulted in identification of bacterial species B. aerophilus strain Imbl 4.1 ‚ Brevibacterium frigoritolerans strain Imbl 2.1 and Pseudomonas fulva strain Imbl 5.1. However‚ these bacterial species‚ causing complete

This process was very slow and ineffective. Later on they started a new method of sap collecting which was attaching a tube to each tree that would all lead to a central station. Scientists

MIC Practical Report Kerry Haarhoff 18 April 2012 3150540 Introduction Bacteria and fungi are both micro-organisms‚ however‚ fungi are spore-producing organisms whereas bacteria are not and fungi can be multicellular and bacteria is only a unicellular organism. These 2 micro-organisms‚ along with many other things circulate in the air within our environment. These micro-organisms then settle and become more prevalent in different areas. An experiment was conducted to see where

Abstract This experiment analyzes the effects of how temperature affects bacterial and fungus amylase and also discovers the optimum temperature for these enzymes. The amylase was mixed with starch at temperatures of 0℃‚ 37℃‚ 57℃‚ and 90℃. Iodine was added to each mixture and colour changes in each case. Bacteria amylase was found to be effective at 55 0C as the temperature dropped drastically from 4.58℃ to 2.33℃. This shows that the amylase catabolized a lot of starch hence little is left which
