Germinated Seeds In The Dark Essay
We accept our hypothesis of the germinated seeds in the dark and the dormant seeds in the dark having a higher rate of cellular respiration then germinated seeds in the light and the dormant seeds in the light. The germinated seeds in the dark had 0mL of change in oxygen levels while the germinated seeds in the light had -.05mL of change in their oxygen levels. The germinated seeds in the dark had a .05mL more for their change in oxygen then the germinated seeds in the light, therefore the germinated seeds in the dark had a higher rate of cellular respiration then the germinated seeds in the light. The dormant seeds in the dark had 0mL of change in their oxygen levels and the dormant seeds in the light had -.16mL of change in their oxygen levels. The dormant seeds in the dark had a .16mL greater change in their …show more content…
The growth that the seeds undergo requires a higher amount of energy in the form of ATP then when they are not spending energy in growth; the extra ATP energy needed by the seed is produced through a higher rate of cellular respiration; which means the seeds will use a greater amount of oxygen (ATP: The Perfect Energy Currency for the Cell). A source of error in this lad be the dipping of hands into the water when trying to read the pipettes which would over lap each other. This error could have been prevented by properly adjusting the pipettes so they would not have overlapped and needed to be moved to be read. Another source of error in the lab in the amount of KOH placed in each vile varying. This error could have been avoided by more carefully measuring the amount of KOH in each vile to insure they contained the same amount. A third error was miscalculating the volume in each vial, which could have been prevented by making sure the beads accurately made up for any difference in volume between the

Pinto Bean Seedlings Experiment
1354 Words | 6 PagesHypothesis: If one-day pinto bean seedlings are soaked in a water solution, 1% NaCl solution, and 3% NaCl solution, the seedlings exposed to higher sodium concentrations will have decreased cellular respiration rates. Treatments: This experiment involved three treatments and a control. The goal of the experiment was to see how different levels of NaCl affect the rates of cellular respiration in day-old pinto bean seedlings.
Red Alder Vs Douglass-Fir Essay
682 Words | 3 PagesDouglas-fir and red alder have seeds that use wings, signifying the use of the wind as a method of seed dispersal. Both trees have seeds than are covered in a seed coat and have nutrient reserves. Gymnosperms, however, have a large megagametophye, which is the haploid nutritional tissue. Angiosperms typically have a smaller megagametophye, that later develops into an endosperm (red alder, however, does not have an endosperm). When seeds germinate, general 4 steps usually occur first: 1) Imbibition, when seeds swells with water and the seed coat ruptures 2) Metabolism increases.

Effect Of Photosynthesis In Spinach
966 Words | 4 PagesFifteen leaf discs were placed in a syringe with water and using the syringe the air was vacuumed out of the leaf discs. The discs were then transferred to a plastic cup with distilled water were the discs sunk to the bottom of the plastic cup. Then the discs were timed on how long it took for half of the fifteen discs to float to the surface. For the treatment groups different concentrations of sodium bicarbonate were added to the distilled water to change the conditions for the leaf discs. After recording the rates of photosynthesis, the mean was calculated by taking the rates measured and adding them together, then dividing by the number of replicants to find the average between them all.

The authors do not use any citations in the
Biology: Photosynthesis And Respiration
593 Words | 3 PagesAs 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?

Results The following graphs show the results of this experiment. The tetrahymena sample that was introduced to concentrated tobacco had a lower cell/vacuole ratio than the tetrahymena sample that was not exposed to
Ap Biology Semester Reflection
609 Words | 3 PagesThis 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
Seed Germination Lab
1145 Words | 5 PagesSince the data will be checked every day around the same time, the data will be constant, which allows validity and reliability to the experiment. Also, there would need to be a large enough sample to have a statistical significance to determine if the age of a seed actually affects the germination period. Lastly, the pots would need to be bigger and less seeds would be put into the pots. This would help the seeds grow at a proper rate because they would not be competing for resources.
What Happens When Can Yeast Metabolize?
451 Words | 2 PagesFor example, in the response experiment, a yeast solution was prepared without sugar mistakenly and thus had to be prepared again. This suggests that other errors in preparation and measurement could have been encountered. For the future, careful measurements using clean uncontaminated flasks would eliminate possibilities of such error. A source of error for the metabolism experiment involves the yeast’s yellow hue. It is possible that the color of the yeast caused the solution to look more
Effect Of Light Intensity On The Rate Of Transpiration
1950 Words | 8 PagesResearch Question: How does the presence of light impact the rate of transpiration in plants? Aim: The aim of this experiment was to investigate how the presence of light affects the rate of transpiration in plants. Hypothesis: As light intensity increases, the rate of transpiration (water uptake) in a plant increases.
Sower Of Seeds
232 Words | 1 PagesThe book of Mathew I found is a book filled with the teaching of parables and instruction of Jesus’s life and his promises to mankind. While reading the book I notice that Jesus had a parable for every life situation which he often uses to explains his teaching of the parables that he was speaking about. One of the parable that I like was the sower of seeds, we as Christians have opportunity to sowed good seeds with people we come in contact with daily, we sometimes miss the moment to sowed our seed into some person life’s, we must try to leave a positive impact on people lives with our seeds. In this passage of the sower i learn that we will receive what we sowed good or bad, when the discipline asks Jesus, why he spoke to them in

Germination Lab Report
750 Words | 3 PagesOne of the many mistakes in the lab was the amount of water that was put into the seeds in the beginning of the lab, upon observing the results, I noticed that all of seeds in both of the containers were completely drowned in water. The lab in a whole was not as successful as one would have expected because of the contradicting results between what happened and what should have happened. From this lab experiment I was able to learn what germination is, cotyledon is, the anatomy of a seed embryo, and how light can affect the way that a seed can
