Yes the hypothesis was supposed, which was "Germinating seed would take in more oxygen because they are actively going through cellular respond growing. This is shown in the data when looking at the Corrected Difference at 5 minutes germinating peas was at .05 and dry peas with beads was only .01, then looking at the data at the end at 20 minutes germinating peas were at .24 and dry peas and beads were at .04. The germinating were ahead of the dry peas with taking in more oxygen. The independent variable was the germination of the peas. The dependent variable was the amount of oxygen consumption. Germinating peas are growing and going through cellular respiration at a higher rate, this effects oxygen consumption because because the higher the
Cellular respiration is the process by which energy is harvested involving the oxidation of organic compounds to extract energy from chemical bonds (Raven & Johnson, 2014). There are two types of cellular respiration which include anaerobic respiration, which can be done without oxygen, and aerobic respiration, which requires oxygen. The purpose of this experiment is to determine whether Phaseolus lunatus, also known as dormant seeds or lima beans, respire. You will compare the results of the respiration rate of the dormant seeds, and the Pisum sativum, or garden peas. In this experiment, you will use two constants which will be the temperature of the water and the time each set of peas are soaked and recorded. Using these constants will help
“Twinkle, twinkle little star. How I wonder what you are. Up above the world so high. Like a diamond in the sky.” In “Snapping Beans,” by Lisa Parker, there are numerous symbols, but the most significant and sentimental one is the evening star. Lisa exploits the evening star to demonstrate how the same thing can still emerge worlds apart, yet at the same time tie people together.
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.
This lab was done to determine the relationship of gas production to respiration rate. The lab was done with dormant pea seeds and germinating pea seeds. It was done to test the effect of temperature on the rate of cellular respiration in ungerminated versus germinating seeds. We had to determine the change in gas volume in respirometers. This was done to determine how much oxygen was consumed during the experiment. The respirometers contained either germinating, or non-germinating pea seeds. I think that the germinating seeds will have a higher oxygen consumption rate in a room temperature water bath than the non-germinating seeds. My reason for this hypothesis is that a dormant seed would not have to go through respiration because it is not a plant yet. A germinating seed would consume more oxygen because it is growing, and therefore would need to consume oxygen by going through the process of cellular respiration.
The “Fast Plant” experiment is an observation of a plants growth over the span of twenty-eight days. The objective is to observe how plants grow and use their resources throughout the span of their life. In our lab we observed the Brassica rapa, a herbaceous plant in the mustard family which has a short cycle which makes it a perfect plant to observe in this experiment. Like other plants the Brassica rapa must use the resources in the environment to create energy to complete itʻs life cycle and reproduce. By observing the plant it is easy to see in what organ or function the plant is using itʻs energy and resources and if overtime the resources switch to other part of the plants. By conducting this experiment we are able to observe where and how plants allocate their resources throughout their life by harvesting plants at different points in their life.
This shows that there could be three variables in this experiment, carbon dioxide, water and light energy. So in our case the variable light energy (light intensity) will be used. The equation also shows that if there is more light energy then more glucose and oxygen will be produced.
1. In Mark Dunn’s Ella Minnow Pea he uses an epistolary format in order to more prominently display the totalitarian rules of the Nollop High Council as well as sequence the plot points of his novel and utilize dates to their importance. He utilizes this writing style in order to convey multiple points of view with easier transitioning through many letters. At the same time the epistolary form also creates a completely different presentation of dialogue and character interactions that can be beneficial to reading and analysis of characterization and plot progression.
... has more CO2 than the negative controls. There will be more spinach circles in the red food coloring than the green and blue food coloring. My hypothesis was supported for both experiments.
Osmosis in Potato Tubes Osmosis: Osmosis is the movement of water molecules through a semi-permeable membrane from a high concentration to a low concentration. Diagram: [IMAGE] [IMAGE] Aim: To see the effects of different concentration of sugar solution on Osmosis in potato tubes. Key factor: In the investigation we change the sugar solution from: 0%-10%-20%-30%-40%-50% this is the independent variable; the dependant variable is the change in mass. Prediction: I predict that all the potato tubes in pure water or low concentration sugar solution will swell because water enters their cells by osmosis.
Dependent Variable ------------------ Rate at which the bubbles of oxygen rise, which will be calculated by observing how many bubbles of oxygen rise to the surface of a measuring cylinder (by means of downward displacement) in one minute. This will be measured in bubbles per ten seconds. Control variables: ¨ Volume of substrate used: 100ml ¨ Temperature: taken place at room temperature 21 degrees centigrade ¨ Type of substrate used: Hydrogen peroxide ¨ Mass of meat used: 5g ¨ Amount of water in the test tube in which the oxygen bubbles downward displaces in the water. This is so the time taken for each individual bubble to effectively rise to the bottom of the test tube will take the same amount of time.
My hypothesis states if the pinto beans are watered with the “acid rain” mixture, then the acid rain would negatively affect whether the pinto bean will germinate because acid rain can wash away nutrients and poison plants with toxic metals which could affect whether the bean germinates. According to my data, my hypothesis was correct even though one of the beans with acid rain did germinate but that is 1 out of 20 beans so it’s very unlikely that it would happen again. My hypothesis was correct because my data proves that the pH of the acid rain mixture does affect whether the bean would germinate. Which makes sense because my background information talks about the negative affect of acid rain on plants. In conclusion my hypothesis was correct
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.
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
A gall is an abnormal growth that occurs on plant tissues. A plant growth is similar to a tumor or a wart that would occur on an animal; plant galls, however, are typically caused by various parasites and insects. In order for a gall to form, a female insect needs to implant an egg into a plant. It is important that the insect does so when the plant is maturing, this ensures the plants meristem is extremely active and prepared to grow a gall suitable for the insect’s young. The larvae and possibly the adult insect as well release chemicals into the plants that causes the growth of the plant. Multiple studies have been done in attempt to find the exact cause for the growth of plant galls, but studies have not reached a similar
This lesson is designed to review and reinforce a few important concepts about plants (e.g. Needs, parts, sequence of planting) and to also guide the students through applying a few scientific inquiry (e.g. Making observations, experimentation, discussion, reflection, reporting results etc.). The students have previously planted corn and bean seeds and today’s lesson has provided the students a chance to see the results of the planted corn and bean seeds. Additionally, seeds have been planted under and growing under the following conditions: without water, and without soil. The students see the results of these seeds planted under these conditions for the past week. Two plants in particular have already been grown their growth has been
