Does Too Much Water Affect The Amount Of Homeostasis In Plants
Through this experiment, we wanted to find out whether different amounts of water would affect the gradual growth of a plant over a long period of time, and this plant maintains homeostasis through this process. My hypothesis was that I believe that the plants would eventually die if it given too much or too less water, and in order to survive, it must have an amount of water that is not in extremes (too much or too less) to regulate homeostasis. As we conducted our experiment, we noticed that the plants that were given 5 mL, 10 mL, and 15 mL (the lesser/ more moderate amounts of water) had grown the most as well as the quickest over 10 days in comparison to the plants watered with the larger amounts of water ( 20 mL, 25 mL, 30 mL etc.) As …show more content…
Because plants go through the process of photosynthesis to mainly produce energy using sunlight, they use something known as the stomata that regulates the amount of carbon dioxide and sunlight is taken into the plant, and how much oxygen is let out. These stomata, when open, can cause the plant to let out a portion of water through evaporation, also known as transpiration. Surrounding these stomata, there are guard cells that control this opening and closing, when open transpiration can increase greatly but when it is closed it is decreased.This can be seen as the feedback mechanism due to its change to maintain homeostasis. Additionally, because pea plants generally thrive better in cool moist areas, they have a greater cuticle thickness, the waxy film that covers the surface of the leaf (USDA,2016). The greater this cuticle thickness, the slower the transpiration rate due to its hydrophobic (water repelling) surface (USDA,2016) and the higher the temperature, the faster the transpiration rate. This can be seen in our experiment as we give more and more water to the pea plant. Because the transpiration rate is much slower due to coolness and cuticle thickness, the plants watered with greater amounts of water (20 mL and above) take
Gummy Bear Lab
219 Words | 1 PagesI predicted this because the water is hypotonic to the gummy bear, so the water would diffuse into the gummy bear causing the cells to swell and increase in size. The control group in this experiment was gummy bears that were not soaked in water because
Spring Water Planarian Lab Report
1075 Words | 5 PagesI tested this experiment by cutting five planarians in half and placing them in the caffeine solution and doing the same for the spring water solution. We placed them in 4 degrees Celsius temperature and waited a week to observe the results. Abstract: The purpose of this experiment was to observe how caffeinated solutions help regenerate planarian growth faster than spring
Science Of Sweat Experiment Essay
795 Words | 4 PagesOne of the issues was pouring the water in the different test tubes at the same time, as only one member of the group poured in the water into the test tube at separate times. This is an issue as it makes the initial temperature for each of the test tubes lower than the recorded initial temperature (43 degrees Celsius) because the room temperature can cool down the water when the timer isn’t activated. It also affects the data as the temperature change for the first 3 minutes can’t be observed, so I can not know if the temperature for each of the test tubes decreased fast or slow from 0 to 3 minutes. This effect has great significance to making the data inaccurate, because the calculated temperature drop most likely is incorrect, meaning the evaluation of the hypothesis - that is based on the temperature drop - could be also wrong. Additionally, I can not observe an accurate reliable pattern between the different tests, because of the altered data.
Lima Bean Plants Lab Report
287 Words | 2 PagesIn this lab experiment the effects of plant growth and the pattern of plant growth in a lima bean plant had been eye opening. Using different liquids had a different outcome on each plant. the different types of nutrients and PH level in each liquid played various roles in the development and growth of each plant. the plant that had been exposed to sprite and milk showed a effective growth and decay starting from day 5. An incredible 3.2 cms was the growth for the plant which was exposed to pond water and on day 5 the plant that was exposed to the liquid of naturel 2% milk showed a decrease of .2 cms.
Cellular Respiration Lab Report
1079 Words | 5 PagesAs the temperature exceeds this value, the rate of respiration will gradually decrease, reaching zero at a certain point. The optimal temperature for germinating pea seed is 20ºC because it is the average temperature of the Spring season in China, where it was first discovered. The trend for the rate of respiration is represented by the graph shown. During the cell respiration process, multiple enzymes are involved, therefore, the rate of reaction will be highest at a certain temperature, and will gradually decrease as the temperature gets further away from that particular
Venus Flytrap Essay
1296 Words | 6 PagesIt is intriguing to think an inanimate plant has evolved to the point that it can quickly react to the stimulation of touch. The most common explanation among environmentalists and ecologists is that is a quick alteration in the turgidity of the plant cells. That means there is a change in the pressure of water located inside of the cells. These cells are located in the lower part of the midrib. Although it is not as simple as stated, it is true that the lower midrib cells consume more water.
Plant Open Stomata Experiment
994 Words | 4 PagesThis is important because any time stomata are open the plant will lose water along with oxygen (berkley) When enough carbon dioxide has entered the stomata, a plant will close its stomata so it can preserve its water and prevent itself from drying out. Environmental conditions can alter stomata density (Tansley reviews). In many species, stomata density is reduced with increases in atmospheric carbon dioxide levels in geological time and under laboratory conditions (tansley reviews). In a study of 100 different plant species, it was found that three quarters of the species analysed showed reduction in stomatal density (Tansley reviews). This would be an advantage for the plant as fewer stomata are better able to conserve water than its original
Beet Cell Membranes Lab Report
197 Words | 1 PagesThe importance of the experiment is to determine the effects temperature has on beet cell membranes, and to understand why certain cells are best suited for certain environments or in this case certain temperatures. Cell membranes play a vital role in selectively allowing substances such as proteins, nutrients, and other chemicals into and out of the cell. The cell membrane is also a line of defense against harmful chemicals and other agents that try to enter the cell. We hypothesize that increasing the temperature will increase the fluidity of the membrane thus making it less permeable. When the temperature of the cell increases it will cause the phospholipids that make up the plasma membrane to move apart from one another and become more
How Fast Does Alka Seltzer Make Gas
621 Words | 3 PagesThe control in the experiment is water. Units used while timing the productivity of gas from an Alka-Seltzer tablet in different temperatures is, seconds. In order to find out if temperature controls the rate of chemical reaction, whether hot water is a more effective way to make the gas produce at a faster speed, it would be necessary to compare the results of different temperatures at the end of each trial. In order to do this the scientists will measure the volume of gas that is produced within a 10 second interval time after the tablet begins to react.
Nahco3 Lab Report
558 Words | 3 PagesThe null hypothesis, “There is no difference in the concentrations of NaHCO3 and the rate of photosynthetic activity.” is rejected. The alternative hypothesis is supported, that which the greater concentration of NaHCO3, the greater the rate of photosynthesis. Since it was found that the p-value was less than 0.05 in table 1 in all five treatments, this allows the null hypothesis to be rejected. This finding correlates with real life observations of faster rates of oxygen production during lab within the higher concentrations of
Egg Osmosis Egg Lab Report
685 Words | 3 PagesBased on the data and the recorded observations, my hypothesis is correct. When a solution is hypotonic, this causes the cell to swell, because there are more water molecules on the inside of the cell. If positive feedback continues, the cell will eventually burst. When a solution is hypertonic, this causes the cell to shrink, because there are more water molecules on the outside of the cell. Over time, the cell will start to function poorly (“Difference between Hypertonic, Hypotonic, Isotonic Solutions”).
Beetroot Experiment
883 Words | 4 PagesWhen the temperature becomes low, the cell membrane is less absorbent and does not permit more substance to pass through the membrane. My results supported my hypothesis which was as the temperature increases so does the beets permeability. In this experiment, there is a human error, as we cut the beet the measurement is near each other but not perfect. The amount of water in each tube would also be a reason for an error in this lab because it was not all equal. Another factor would be, temperature because some were long and some were short.
Zucchinis Experiment
526 Words | 3 PagesPlants also need water to grow. For this experiment for all three cells i will pour 30ml of water over all cells. Radiation might be the solution to have plants grow faster without waiting forever for your plant to grow. Except you still need the water and sunlight. There are many different types of radiation.
Effect Of Light Intensity On The Rate Of Transpiration
1950 Words | 8 PagesBackground Information: In this experiment I will be investigating the impact of light intensity on the rate of water uptake, due to transpiration, by attaching a shoot from a leafy plant in the capillary tube of a potometer, and then measuring how long it takes for a bubble to move a set distance. The faster the bubble moves, the greater the rate of transpiration. I will be placing one plant in an environment where it is exposed to high-light intensities, and another plant in an environment where it is exposed to low-light intensities. Transpiration is the process of the transport of water and nutrients up the the plant from the roots to the leaves.
Water Potential Osmosis Experiment
743 Words | 3 PagesThis conveys that sucrose concentration shall affect water potential, therefore the higher the sucrose concentration, the lower the water potential. This is how osmosis is linked to water potential and why experiments testing osmosis can be used to create methods to find and/or test water potential within plants. In addition to this, concentration of sucrose in a solution and in a plant cell or plant tissue shall have an effect on water potential.
