The primary nutrients that plants require are carbon, hydrogen, and oxygen from air and water. Sugar has a different effect on animals, humans, and plants. In this experiment, we are testing the effects of sugar on the growth of wheatgrass. For this experiment, we used regular sugar that we put in our food and drinks. To test our hypothesis we are using two groups control and experiment group. The control plant received only water but the experimental plant received sugar but, both plants were placed in the same temperature and same amount of water. Our hypothesis was correct, experiment plant “sugar water” yield more plant growth than control plant “water”. This experiment shows the sugar water plant grow faster than water because of the average of both plants. The sugar water experiment plant had longer in length compared to water control plant. Introduction During the four-week period, …show more content…
We used wheatgrass were 40 wheatgrass seeds, two empty pots, soil, and water. We first added soil for both pots and 20 wheatgrass seeds in each pot. My partner and I decided that we label pot one experiment which is “sugar and water” and pot two control which is “water” only. The experiment was for almost four weeks we had to make sure both get the same room temperature and water, so we can see the results after this amount of time. Both pots had same room temperature so both can have the same amount of sunlight also, the same amount of water which is a glass of water from the sink once a week. In the experiment pot we added a glass of water with one teaspoon of sugar and the control pot glass of water. Every week we used to see both pots grow almost the same. At the end of the experiment, my partner and I measured the length for both plants and we recorded the average for each plant, so we can know the rate of growth
The data which has been collected from the Garlic sprouting experiment proves to be inconclusive; however this is not to say that the data was not informative, or did not have influence on the questions being asked in the lab. The lab question states “Do insecticides and pesticides used on Industrial Garlic negatively impact the rapidity of growth of sprouts; in comparison to Organic Garlic?”. In answering this question, growth must be studied through time period, and quality of length. When looking at the data from Table 1, it can observe that on May 12 Industrial Garlic grew 1 sprout more than Organic did and on May 17 the Industrial Garlic grew 5 more sprouts than Organic did. However by May 20, just 8 days after initial growth (on May 12), the Organic Garlic has grown more by 7 sprouts. From the point forward, it seems as though Organic Garlic continued to out-sprout Industrial Garlic, until you look at May 25, the last data collection day. At this time you realize that Industrial Garlic had 31 sprouts but Organic Garlic only had 29 sprouts. Looking at Graph 1, we can see that both Garlics have an overall growth trend, in which Organic Garlic seems to start off slower, and grow more exponentially toward the end of the data collection period, but between May 20 and May 24 the data looks as thought it would have started to crash, if growth were to be continuously monitored after the 20 day time period. Industrial Organic seems to have a similar trend, yet the growth in Industrial Garlic seems to climb in sprout count less rapidly than the Organic brand did. It can also be observed that although the Industrial band Garlic dips significantly on May 19, it continues to rise once again for the rest of the time period. This indicat...
The fair testing will be carefully checked so the results do not come out to be void. The light intensity will be changed for it is the only variable used in the experiment. Though the temperature, watt of the bulb, amount of water, size of the plant and posit...
To make the test fair I will use the same amount of water and the leaf
Six weeks previous to the conductance of this lab, Biology 108 section,planted wheat and mustard plants according to table#1 on page 3 of the Principles of Biology 108 Lab Manual . This table depicts all of the total pots and number and type of seeds planted in the pots. It accounts for the experiments of the intraspecific competition and interspecific competition. Replicates of each pot were planted to add precision and more acceptable statistics. Therefore, there were 40 pots, that is, 20 treatments conducted twice(Ciara, 1993).
the effect light has on the growth of pea plants. It will take place in an environment with controlled light, with equal amounts of plants being grown in the light and in the dark. All elements of the experiment other than light will be kept the same, such as amount of seeds in each pot, amount of soil in each pot and amount of water given to each plant each day. This will ensure a fair experiment. Prediction: I predict that in general, the plants grown in the light will grow better than those grown in the dark.
My group, fertilizer group 3, is testing the variables of plant color and number of leaves. Fertilizer can affect that drastically! Those two variables are basically what determine a healthy plant. Fertilizer can help to boost the minerals in the soil and give the plant what it needs to survive and be healthy.
Two members of the group were instructed to visit the laboratory each day of the experiment to water and measure the plants (Handout 1). The measurements that were preformed were to be precise and accurate by the group by organizing a standardized way to measure the plants. The plants were measured from the level of the soil, which was flat throughout all the cups, to the tip of the apical meristems. The leaves were not considered. The watering of the plants took place nearly everyday, except for the times the lab was closed. Respective of cup label, the appropriate drop of solution was added to the plant, at the very tip of the apical meristems.
In our Biology Lab we did a laboratory experiment on fermentation, alcohol fermentation to be exact. Alcohol fermentation is a type of fermentation that produces the alcohol ethanol and CO2. In the experiment we estimated the rate of alcohol fermentation by measuring the rate of CO2 production. Both glycolysis and fermentation consist of a series of chemical reactions, each of which is catalyzed by a specific enzyme. Two of the tables substituted some of the solution glucose for two different types of solutions. They are as followed, Table #5 substituted glucose for sucrose and Table #6 substituted the glucose for pH4. The equation for alcohol fermentation consists of 6 Carbons 12 Hydrogens 6 Oxygen to produce 2 pyruvates plus 2 ATP then finally the final reaction will be 2 CO2 plus Ethanol. In the class our controlled numbers were at Table #1; their table had 15 mL Glucose, 10 mL RO water, and 10 mL of yeast which then they placed in an incubator at 37 degrees Celsius. We each then measured our own table’s fermentation flasks every 15 mins for an hour to compare to Table #1’s controlled numbers. At
Lima bean and wheat seeds will be used and it takes about five days to germinate. The independent variable will be the molarity of aspirin water from 0.2, 0.4, 0.6, 0.8 and 1.0 M. Molarity is used to express concentrations of plant hormones. The height of the lima bean and wheat seed plant when finished growing is the dependent variable. The growth will be measured using a ruler in centimeters to see which plant responded better to aspirin water. The plants will be grown in Dixie cups with an equal amount soil and will be given 100 mL of aspirin water. The seeds in will be placed with 1 ½ - 2 inches deep in the loose and fertile soil. The seeds will have several days to grow and germinate before it will be measured for growth. In conclusion, if the plant with aspirin water grew longer than the plant with distilled water then it shows that aspirin water can help improve the growth and germination of
Water Relations in Two Plant Tissues Results: Table 5 Table to show the sucrose concentration and water potential of each tissue. The sucrose solution was extrapolated from graph 1, which shows the percentage change of mass of the tissues when immersed in the different sucrose solutions. A line of best fit was drawn, where the line of best fit intercepts the x-axis (concentration of sucrose solution) is the sucrose concentration of the tissue because at this point there is no mass loss of gain (read off of y-axis).
Every student in a lab section planted eight seeds, two in each cell in a quad, to make sure that we had at least one plant for each week for 4 weeks. After planting the seeds we put the plants on a water mat tray to make
We then put the stopwatch on and left them for half an hour. After we weighed each potato tube and recorded our results. We did the experiment twice. We did this to make sure our results were correct. Preliminary method: We did everything the same as in our other experiment except we
Thus, the aim of this experiment is to investigate the effect of light, planting depth and hormones on seed germination.
Sugars are carbohydrates naturally occurring in foods such as fruit, vegetables milk and grains, providing dietary energy, sweetness and various functional properties in food applications. It has been used as a food stabilizer and an essential ingredient in domestic food preparation and preservation for centuries. There are several types of sugars including sucrose, a disaccharide (C12H22O11) composed of fructose and glucose naturally occurring in fruits and vegetables and lactose derived from milk. Sucrose is the end product of the photosynthesis process in plants and is extracted for commercial use and consumption. Main source of sugar is derived from high sugar containing plants such as sugar beets and sugar cane and may be further manufactured into different types of sugars, including brown sugar, powdered sugar or liquid sugar. It is widely used in foods and beverages to enhance sensory attributes including sweet taste, flavor and texture as well as other physical and chemical properties. (Linden, Lorient, 1999)
This lab attempted to find the rate at which Carbon dioxide is produced when five different test solutions: glycine, sucrose, galactose, water, and glucose were separately mixed with a yeast solution to produce fermentation, a process cells undergo. Fermentation is a major way by which a living cell can obtain energy. By measuring the carbon dioxide released by the test solutions, it could be determined which food source allows a living cell to obtain energy. The focus of the research was to determine which test solution would release the Carbon Dioxide by-product the quickest, by the addition of the yeast solution. The best results came from galactose, which produced .170 ml/minute of carbon dioxide. Followed by glucose, this produced .014 ml/minute; finally, sucrose which produced .012ml/minute of Carbon Dioxide. The test solutions water and glycine did not release Carbon Dioxide because they were not a food source for yeast. The results suggest that sugars are very good energy sources for a cell where amino acid, Glycine, is not.
