The variation of the concentration of sodium bicarbonate will have an effect on the rate of photosynthesis of spinach (Spinacia oleracea). As the amount of sodium bicarbonate increased the rate of photosynthesis also increased, this is because bicarbonate provides carbon dioxide (CO2) for the photosynthetic reaction which was also found in the experiment: An Assay Utilizing Leaf Disks (Guy, 1985). When completing this experiment there was one mane issue with our experiment that might have affected the results. The main issue that was faced was when the leaf disks were being exposed to the higher percentages of sodium bicarbonate while they were being vacuumed in the syringe. We found that the sodium bicarbonate was reacting with the leaf disks before they were placed

The plant that was exposed to the light more intensely produced more bubbles. 3. What would you suggest is the function of the sodium bicarbonate?

In addition to oxygen and carbon dioxide, the circulatory system is the primary delivery system for? A.cerebrospinal fluid B.exocrine secretions C.biliary fluids D.endocrine hormones 39. a biology class wants to perform an experiment to investigate the effect of different colors of light of green, yellow, red and clear cellophane and plant three seeds in each one. What part do the three seeds experiment?
The coastal temperate rainforest is a 2,500 mile long narrow rainforest that borders the west of North America. It is the largest coastal temperate rain forest in the world. It receives an annual precipitation of 33-105 inches of rain. with 350 bird and mammal species, 48 species of amphibians and reptiles, 25 tree species, hundred species of fungi and lichens, and thousand species of mites, insects, spiders, and other soil organisms the rainforest is rich in biodiversity. One of the species that lives in this habitat is the Polypodium glycyrrhia more commonly known as a licorice fern.
Substrate concentration basically means the amount used for the substrate. The substrate in our experiment was 0.1% hydrogen peroxide. The 0.1% is the concentration amount. Just like temperature and pH, substrate concentration can speed the reaction only up to a certain limit. When we mixed pH 3 enzyme tube with substrate tube, we used 0.3 mL of hydrogen peroxide, but if we were to increase the amount, then the experiment would have been faster.
Doriana Spurrell What different frequencies and types of light would prompt the Spinach leaves to go through the process of photosynthesis effectively? Purpose: The purpose of this experiment was to see which of the four lights that range across the light spectrum would properly and most efficiently help the spinach leaf perform photosynthesis. Background Information: Photosynthesis is the process in which plants use light energy to transform into chemical energy. The process of photosynthesis is vital for the survival of most life on Earth. Without photosynthesis plant life would be unable to create its own food and sustain themselves causing them to die.
Maia Naylor and Margot Cathelin 10/21/2015 Grade 9 Enzyme Lab Report Purpose: Which temperature of potato (freezing, room temperature, boiling) when added to hydrogen peroxide, would produce the most enzyme activity? Research Question: How does hydrogen peroxide break down enzymes? When hydrogen peroxide and enzymes meet, they instantly form a reaction. This reaction is the chemical distillation of enzymes. The reaction is enzymes breaking down and turning into bubbles.
The plant used in this lab was Phaseolus vulgaris, or the common bean. This plant does C3 photosynthesis. First, my partner and I got two pots with a bean plant in each. In order to get the most accurate and relevant results when compared to one another, the bean plants were relatively the same size. The plants beforehand each had two larger leaves, three smaller leaves, and three leaves in bud form.
Thereafter we see an exponential increase in the production of carbon dioxide. This means there is a great activity in the break-down of the two sugar substrates by yeast. The control of this experiment lacked sugar but had two times the yeast; the yeast alone produced carbon dioxide that occupied the 5 mm subtracted from the experiment. The minute amounts of carbon dioxide that are produced result from fermentation undergone by yeast cells using the sugars that are already in their system (Barnett and Lichtenthaler,
1mL of this solution was dissolved with 1mL of 10% v/v methylene blue solution and left for 10 min. Aliquots of 1μL were placed on the haemocytometer by using a Pasteur pipette. The haemocytometer was then microscopically observed by an optical microscope (Olympus model CHK2-F-GS microscope). Yeast cell viability was calculated and expressed as
