Germinated Seeds In The Dark Essay

387 Words2 Pages

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

Red Alder Vs Douglass-Fir Essay

682 Words | 3 Pages

Douglas-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.

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?

What Happens When Can Yeast Metabolize?

451 Words | 2 Pages

For 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

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

Sower Of Seeds

232 Words | 1 Pages

The 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

I observed that Kim aided in comprehension when asking questions in her read-alouds, creating post-reading activities and fostering discussion about book events. Kim used the book, The Tiny Seed by Eric Carle, asked open-ended questions and created book-based activities throughout the two days I observed. State Senator Marc C. Panepinto facilitated comprehension when he read the book, The Very Hungry Caterpillar by Eric Carle and discussed the events that took place with the children. He asked questions that allowed the children to connect the book to their own backgrounds (ex. Have you ever been really hungry?).

RESEARCH QUESTION Which one has a higher rate or respiration between dicotyledonous (peas) and monocotyledonous (maize) seeds and what is the effect of temperatures (room temperature, 40, 60) on the rate of respiration as determined by oxygen usage estimated with a respirometer? AIM The aim of this experiment is to investigate which seed has a higher rate of respiration and how different temperatures (room temperature, 400C, 600C) affects the rate of respiration of dried, fresh and germinating monocotyledonous (peas) and dicotyledonous (maize) seeds.

Seed Germination Experiment Essay

747 Words | 3 Pages

Seed germination is crucial when looking at a seed's life. It is the beginning of its existence and plays a key role in how the seed will grow from there on out. When looking at seed germination dealing with various salt concentrations, the outcome of the experiment can result in many factors. If salt concentrations affect the rate of seed germination, then a positive control of water would germinate faster than the affected seeds with various diluted salt concentrations. In the end, the effect of the assorted salt concentrations does tend to slow down the rate of germination with all of the different concentrations.

Seed Dispersal Project Essay

Seed Dispersal Project by Ben Fesenmyer   Introduction   Plants make seeds to ensure the continuation of the species. The seeds that the plants make need to travel to get nutrients sunlight and water seed dispersal is how plants spread the seeds. There are 3 ways to spread seed by water by animals and by wind, in my project we are spreading seeds by wind. Wind dispersal is the most common method to spread seeds, the three main types of devices that carry seeds they are helicopter, glider and parachute. The helicopter way of dispersal uses one or two blades and a spinning motion to spread seeds.
