Photosynthesis/Scientific Method Worksheet
Photosynthesis/Scientific Method Worksheet 1. State and explain your pre-experience hypothesis: We were supposed to place (Elodea) in two tubes, which one should closer to a light source and the other with no light on it. The experience consisted in observe and count the amount of bubbles coming out from the plant in both tubes.
Hydrochlorimetry Lab
When testing the effects of hydrochloric acid on different solutions data was collected that showed that liver cells have a buffer and celery do not which supports the original hypothesis of liver cells containing a buffer. A buffer is a solution that resists change in pH when acid is added to it. A buffer will release more hydroxide ions when there is acid added. Each solution in the lab was tested first at its original pH and then after five drops each was tested until there were 30 drops added in. When tested in the lab two controls were used one positive for having a buffer (alka seltzer) and one negative (water).
Spinach Leaf Photosynthesis Lab Report
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.
Effect Of Photosynthesis In Spinach
This experiment is set up the study the effect of different sodium bicarbonate concentrations on the rate of photosynthesis in spinach (Spinacia oleracea). Photosynthesis is the process by which plants and other photoautotrophs synthesize organic compounds from carbon dioxide (Faculty of Science and Horticulture, 2018). Photosynthesis takes place in the chloroplast of a plant cell, where sunlight, water, and carbon dioxide are used in a reaction to produce oxygen and sugar (Reese 2017). In the photosynthesis reaction carbon dioxide is reduced to make sugar and water is oxidized to make oxygen. In this experiment oxygen production is being used to measure the rate of photosynthesis.
Photosynthesis Lab Report
The first step of the creation of verdigris was preformed using the following reaction (1): 4CuSO4*5H2O(aq) + 6NH3(aq) CuSO4*3Cu(OH)2(s) + 3(NH4)2SO4(aq) + 14H2O(l) Based on this chemical equation, four moles of hydrated copper sulfate reacted with six moles of ammonia to produce a precipitate of copper sulfate tribasic along with aqueous ammonium sulfate and liquid water. It was known that a chemical reaction was occurring when the ammonia was being added via the color change from light blue to dark blue. The precipitate formed from this solution was acquired via vacuum filtration, which involved the solution being separated from the precipitate via air pressure flowing out of the flask. The air pressure flowing out of the flask was caused by a faucet that was running water which was attached to a tube that was attached to the collection flask.
Photosynthetic Rate Lab Report
How Calcium Effects Bean Plants Photosynthetic Rate Tristen Webber Introduction In this study I measured the growth of a bean plant over 13 days and then measured the photosynthetic rate by measuring the amount of chlorophyll a in the leaves of the plants. Photosynthesis is the process of plants creating glucose from, water, carbon dioxide and sunlight. Photosynthesis depends on the absorption of light from pigments in the plants leaves. I tested how calcium would affect the photosynthetic rate of the bean plant.
Photosynthesis Lab
Photosynthesis stuff James Harris Introduction This study hopes to determine which photosynthetic pigments are prevalent in spinach plants. These pigments help to carry out the function of photosynthesis which is the process of utilizing light energy to construct sugars. They assist photosynthesis by absorbing light of specific wave lengths. This process leads to the production of one of the most basic forms of energy on our planet.
Column Chromatography Can Separate The Color In Sodas
“Column chromatography in chemistry is a chromatography method used to purify individual chemical compounds from mixtures of compounds.” Chromatography is when the chemical is purified using another compound. Column chromatography is when different liquids are separated from each other. All the different types of chromatography separate chemicals from each other but they do it in different ways.
Algae Growth Lab Report
The purpose of this lab was to test the effect of pollution on algae growth. Through a series of experiments that lasted a month, four of the six hypotheses were proven to be correct or partially correct. The first hypothesis stated that if 0.5 mL of salt was added to algae, then the algae would grow slower than the positive control. This was proven correct, as shown by the difference of the data from the positive control and the container with 0.5 mL of salt in it.

Quinn Nguyen Floating Leaf Disk Photosynthesis Lab Conclusion: Graph your results for all 3 trials on one graph. Label the graph, both axes, and provide a legend to distinguish each trial. What was the rate of photosynthesis for each variable? How many leaves floated per minute? Rate of photosynthesis (leaves/min) Spinach: (2-0)/25 = 0.08
Light And Photosynthesis Essay
Title Which frequencies and type of light aided and affected the efficiency of photosynthesis or carbon dioxide consumption in a spinach leaf? Purpose The purpose of the experiment/lab was to observe the effectiveness of different lights during the process of photosynthesis. Background Photosynthesis is a biological process.
Azolla Photosynthesis
In this process,phenolic compounds such as caffeic acid and tannin are extracted from a water fern called azolla mycrophylla, this plant does not have seed or flowers. Both these acids have immense potenial roles Caffeic acid as an antioxidant,anticarcinogenic as well as anti-inflammatory while tannin has been used to treat various diseases along with acting as a shield from external attackers like predators in plants. The extraction procedure started from the crushing of the dried azolla plant material converting it into powderous form so as to mix it with a solvent such as petroleum ether instead of ethanol for further mixing and then it is placed inside a UV sonicator before filteration using a funnel and filter papaer for removal of the plant debris,after using a seperating funnel for seperation it is placed in a rotary evaporator so that the solute and solvent gets seperated as the solvent that had been initially used is seperated out along with drying of the rest of the material which can be further used for the analysis of caffeic acid as well as tannin and for their further analysis using aspectrophotometer. Spectrophotometer analysis gave the exact peaks at the particular wavelengths. These acids have olso
Red Cabbage: Brassica Oleracea
Brassicaceae, is the family that red cabbage belongs to[2]. Red cabbage contains the source of anthocyanins, this anthocyanins contribute the colour to this plant. Since the anthocyanins are unique, by being wisely in colour range by its characteristic which is an indicators. This plant pH-range was very broad compare to others anthocayanins from, e.g. grape skin, elderberry and black current, which only can take a limited degree of colour at pH<4. While anthocyanin in red cabbage can perform
Carotenoids Essay
They are lipophilic bioactive components and responsible for bright red, yellow and orange colors in many fruits and vegetables. They are mainly found in chloroplast and chromoplast of plants and photosynthetic bacteria. There are six types of carotenoids including; α-carotene, β-carotene, lycopene, lutein, zeaxanthin, and crocetin. Carotenoids with molecules containing oxygen are known as xanthophylls (lutein and zeaxanthin), while oxygen free carotenoids are known as carotenes (β-carotene and lycopene). There are several human health benefits that have been related with carotenoids.
