Germinating Peas Lab Report

778 Words4 Pages

Analysis The lab conducted was able to demonstrate the basic concept of cellular reputation by observing germinating peas and non-germinating acrylic beads. As time progressed, the overall volume of the germinating peas continued to decrease while the acrylic beads remained relatively constant. After thirty minutes, the volume of the peas went from 7.75 mL to 6.00 mL, a difference of 1.75 mL. However at the same time, the acrylic beads went from 8.25 mL to 8.00 mL, a mere 0.25 mL difference. While the germinating peas produced large differences between its oxygen consumption, the beads had only slight changing intervals. This leads to conclusion that the respiration rate of the germinating peas was faster than the respiration rate of the acrylic beads. …show more content…

As the peas are germinating, .they require a larger amount of ATP to grow and survive. This then allows the peas to have a higher rate of respiration than the beads. While germinating plants grow, they need to consume more oxygen than plants which have stopped growing. This therefore allows germinating seeds have higher metabolic demands, which then results in a higher rate of respiration compared to non-germinated seeds. Since the acrylic beads are not alive and developing, they do not respire and do not require a significant amount of ATP for production. For that reason, the beads will always have an overall lower rate of respiration in comparison to the germinating peas.These results were to be expected as the germinating peas are living variable, therefore needing cellular respiration to survive. Also as the data proved our group’s prediction, the acrylic beads would experience little to no change in over oxygen consumption due to it being non-living

Rhubarb Osmosis Lab Report

1127 Words | 5 Pages

Additionally, it was difficult obtaining a piece of rhubarb that was thin and particularly red, therefore the effect could not be best observed in the cells. Part B: Design your own experiment Parts of this practical were taken and slightly altered from the following link http://www.markedbyteachers.com/gcse/science/investigate-the-effect-of-surface-area-on-osmosis-in-potato-tissue.html Aim: To observe the effect different surface area: volume ratios have on osmosis in potato tissue. Hypothesis: If the potato has a larger surface area: volume ratio, the quicker osmosis will take place and the larger the mass will be at the end of the experiment, therefore the difference in mass of the potatoes from the start of the experiment to the end of the experiment will be larger. Additionally, the potato pieces left in a saltwater solution will decrease in mass, whereas the pieces left in water will increase in mass.

Biology: Photosynthesis And Respiration

593 Words | 3 Pages

As stated in the background of the lab, "seeds are considered to be in a period of dormancy, where they metabolize stored energy at a very slow rate while the seed is still considered alive" (Hands On Labs). During germination, the developing plant embryo uses the stored food supply in the seed for cellular energy and growth. Thus, cellular respiration is taking place as the seeds grow. Without water the seeds cannot begin germinating thus the seeds in test tube N did not undergo photosynthesis(Hands On Labs). B. Were the seeds in the “G” tube undergoing both photosynthesis and respiration, only photosynthesis, or only respiration?

Spinach Leaf Photosynthesis Lab Report

1169 Words | 5 Pages

Because carbon dioxide is absorbed by the plant during photosynthesis less carbon dioxide present in the chamber is a sign that photosynthesis is working. The four lights used for this experiment range across the light spectrum on both sides in order to test a wider variety of wavelengths. All lights will be placed directly on the spinach leaf at the same distance so as not to give any spinach leaf a different light intensity, which could affect the data. This experiment will be able to show which light, ranging across the light spectrum, will allow the Spinach to perform photosynthesis more efficiently.

What kind of government is the High Council? After reading Ella Minnow Pea, one might be appalled at the amount of power the Nollop High Council has. The High Council, convinced the people that the letters were falling for a reason; as a result, the Council started to make laws banning usage of the fallen letters. In the real world, the High Council could be compared to some of the most infamous dictators; because both the High Council and dictators share the same methods of enforcing their rule, and both have complete power. The High Council in Ella Minnow Pea, is not only the enemy in the epistolary, but is also representative of the power mad enemy in our world, totalitarianism.

Mitochondrial Activity Lab Report

2102 Words | 9 Pages

First, it was hypothesized that test tube "A", the control, would not show any red concentration, test tube "B" which contains supernatant II would show the most red concentration and test tube "C" which contains sediment II would only show a little red concentration. The second hypothesis states that the raw corn kernels would have mitochondrial activity while the boiled corn kernels would not. The last hypothesis interprets that the "gunk" and sediment I will both contain starch granules. It was only expected to find mitochondrial activity in Supernatant II. Unfortunately, after performing this experiment, we were not able to support this hypothesis and come up with a conclusion.

Our Hypothesis stated in the introduction of the paper was correct. The potato slices in the sucrose solution lost weight (grams), while the potato slices in the water gained weight (also in grams). Osmosis definitely occurred during this experiment. In one short hour changes can be seen between the weights of the potatoes. The skins on the potatoes are made of cellulose, membrane which does not allow osmosis to occur, or water to pass through under normal circumstances.

These days scientists know how you inherit characteristics from your parents. They're able to calculate probabilities of having a specific trait or getting a genetic disease according to the information from the parents and the family history. But how is this possible? To understand how traits pass from one living being to its descendants, we need to go back in time to the 19th century and a man named Gregor Mendel. Mendel was an Austrian monk and biologist who loved to work with plants.

Why Is Chlorine So Important?

761 Words | 4 Pages

In conclusion, the data rejected the hypothesis that states if plants are grown in various solutes, including distilled water, acetone, aspirin, and chlorine, then the chlorine solution will have the fastest growing plants. According to the chi square, there was no significant difference between how long it took for the plants to grow in the different solutions. This was because the chi square value was .3 which is less than the critical value which is 7.82. This is contrary to previously found research, that stated how chlorine is a necessary component to plant growth and would also be an aid in plant growth (Rhoades, 2015). The reason why chlorine is so important is because it is an essential element in the plant.

Does Too Much Water Affect The Amount Of Homeostasis In Plants

589 Words | 3 Pages

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).

This is very similar and related to the previously discussed objective of being able to identify biological processes that require energy. Modeling the way organisms capture and store free energy was achieved in several different labs, including the cellular respiration lab. In the lab, we modeled how an organism can capture and use energy through facilitating the germination of seeds. Germination is a very complex biological process that requires the capture and storage of energy for later use. Modeling this process allows further investigation and greater understanding of how energy is captured and used by

Effect Of Light Intensity On The Rate Of Transpiration

1950 Words | 8 Pages

Background 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.
