Materials and Methods This experiment required 30 Alaskan Pea seeds, 3 pots (4 1/16in x 2in), two 60in Vigoro Sturdy Bamboo Plant Stakes, one API Nitrate (〖NO〗_3^( -))Test Kit, one API Phosphate (PO_4^(-3)) Test Kit, half of one bag of 3.7L bag of Earthgro: The Natural Choice Potting Soil, 10 Red Wriggler Earthworms (Eisenia foetida), 2 mesh strainers (1 small, 1 big), one 400mL beaker, 4 glass tubes, one 12in ruler, Garden Clippers, Greenhouse, Greenhouse Thermometer, Greenhouse Watering Can, and a Sink, 4 Paper Towels, and a 3inx2in rectangular container. I labeled the 3 pots with orange tape, 1 was labeled experimental phosphate, 1 was labeled experimental nitrogen and the last one was labeled control. First I obtained 3 pots and one 3.7L…
In experiment one, involving the rate of respiration of germinated peas when exposed to a variety of different temperatures. From a general standpoint the data collected matched the hypothesis formed, as the temperature increases the rate of respiration will increase as well. This was shown as the average ppm of oxygen was taken from each group. Comparing the data from the class is shows the effect of human error on the results. For example group #4 seemed to have back wards results this may have been due to an improper seal on the oxygen sensor.…
The apoplast is important for all the plant's interaction with its environment. The main carbon source (carbon dioxide) needs to be solubilized in the apoplast before it is taken up by chloroplasts and consumed during photosynthesis. In the roots, ions diffuse into the apoplast of the epidermis before being taken up into the symplast by specific ion channels and being pulled by the plant's transpiration stream, which also occurs completely within the boundaries of the apoplast. Similarly, all gaseous molecules emitted and received by plants such as plant hormones and other pheromones must pass the apoplast. The apoplast is also a site for cell-to-cell communication. During local oxidative stress, hydrogen peroxide and superoxide anion can diffuse through the apoplast and transport a warning signal to neighboring cells. In addition, a local alkalinization of the apoplast due to such a stress can travel within minutes…
At intervals of 20, 40, and 60 minutes, the tubes are removed. Record the volume of gas produced in each fermentation tube. Each tube is graduated in tenths of a milliliter. (HINT: Look at the amount of gas, not the level of the liquid.)…
Photosynthesis is a process to which some autotrophs such as plants produce their own food. It has two stages or reactions light-dependent and light-dependent reactions. The light dependent reactions are the first stage, where energy from sunlight is captures in Photosystem 2 and then 1, the electrons generated in Photosystem 1 then moves along the electron transport chain. The moving of electrons causes a hydrogen ion gradient that is used in the final step to produce ATP, by the ATP Synthase. The equation for this reaction is 6CO2 + 6H2O C6H12O6+6O2 or, carbon dioxide +water sugars + oxygen . This reaction takes place on the thylakoid membrane of the chloroplast and uses energy from sunlight to produce compounds like ATP and NADPH. The second stage of photosynthesis is the Calvin Cycle, which takes place in the stoma of the chloroplast. This stage is light-independent or it does not need energy from sunlight. During this reaction ATP and NADPH from Stage 1are used to produce high energy sugars. The reaction is 3CO2 + 6NADPH + 5H2O + 9ATP G3P + 2H+ + 6NADP+ + 9ADP + 8Pi . Additionally, the three limiting factors of photosynthesis are the light intensity, carbon dioxide concentration, and the temperature. Lastly, the items used in this particular experiment were baking soda to provide CO2, a light to excite the electrons in stage 1, distilled…
Due to the control, non germinating peas/beans are releasing less CO2 ppm than the 24 hour and 48 hour germinating peas/beans. This can be seen when the control from 0-5 minutes was at -76 ppm, while the 24 hour beans were at +374 ppm. The alaskan peas also saw this same type of pattern from 0-5 minutes. The control for the peas was at -176 ppm and the germinating peas were at +1,056 ppm. Since this lab was conducted with precision, and the sensors were not broken, or tampered with before, during or after the experiment, this data is accurate which leads to precise…
photorespiration rates increase with increasing temperatures in C3 plants, the loss of CO2 by photorespiration in C4 plants…
Hypothesis 1: If the pea seed is in the light then the pea seed won’t grown as fast compared to the radish seed in the light.…
We conducted this lab in order to determine the relationship between gas production and the cellular respiration rate between germinating peas and dormant peas. Cellular respiration is the procedure of changing the chemical energy of organic molecules into a form of energy that can be used by cells called ATP (adenosine tri-phosphate).…
The purpose of this lab is to observe how influential light is to the construction and/or use of CO2 and O2 amongst plants. This can be examined by experimenting the effects of plants under both light and no light.…
In this experiment we used dried split peas to extract the DNA and observed the protein isolate.…
A kind of food i think is absolutely repulsive is Brussel Sprouts. They are the most nastiest things on earth. Every time I even hear the word brussel sprouts I want to puke. The smell is even worse than the food itself, Actually they are equally horrible and distasteful. Ever since I had first tried them (when i was 8 years old.) I thought that they were gross. If someone offered me 1 million dollars to eat one i wouldn't. Brussel sprouts to me are poison and every time I am offered I will decline.…
Greater loss of carbon dioxide from test tubes closer to the light and containing sprigs supports the…
Culture often times can impact one’s perspective on things in the world. Culture does inform the way we view the world and others. There are many factors that influence a person's perspective, culture is one of the most important elements in shaping the way he/she views the world. We are surrounded by culture and see differently everyday. Many believe that culture influences how we judge and see things around the world.…
Photosynthesis is the process by which plants create food for themselves which occurs in the cytoplast organ of the cell. They absorb carbon dioxide, water, and solar energy to produce glucose and oxygen (Doc C). Cellular respiration on the other hand, is the process occurring in the mitochondria by which organisms create energy to power cellular processes. This process takes in glucose and oxygen to create carbon dioxide, water, and energy in the form of ATP (Doc C). These processes follow the law of conservation of matter and energy as the amount of products is always equal to the amount of reactants in a chemical equation. So the amount of glucose and oxygen created during photosynthesis is equal to the amount of carbon dioxide and water used and the amount of carbon dioxide and water produced during cellular respiration is equal to the amount of glucose and oxygen used. Many people notice that the products of cellular respiration are the reactants of photosynthesis and the products of photosynthesis are the reactants of cellular respiration. This is because the two processes work together to provide organisms with food and…
