For 5⁰C, the graph showed that it took 2 minutes for the bubbles have risen 0,5 mm in height. For 10⁰C, the graph showed that it took 2 minutes for the bubbles to rise at 2mm. For 20⁰C, the graph showed that the bubbles had a constant height with 1-2 minutes. For 50⁰C, the graph showed that it took 2 minutes to get to 3mm in height. For 80⁰C, the graph showed that the bubbles did not increase in size and stayed the same within 0.5 – 2 minutes Conclusion: The enzyme are found in both animal and plant cells.
This energy is normally obtained from the sun. When sunlight strikes the plant leaves the chlorophyll pigments within the leaves traps it, chlorophyll is found in chloroplasts which gives the leaves a green colour. Some of the trapped energy is used to break up water molecules into hydrogen and oxygen. The oxygen molecules are then given off into the air and the hydrogen molecules are combined with carbon dioxide to form a sugar called glucose (Great Illustrated Dictionary, 1984). Glucose is the basic food source and it assists with the growth of the plant (Roberts et al, 1993).
Purpose: The purpose of this experiment is to see how long it takes for the 10 spinach leaf discs to undergo photosynthesis and thereby rise in the two solutions. Hypothesis: All of the leaf discs in the sodium bicarbonate solution should be floating before the discs in plain water because the bicarbonate is a carbon source that will allow photosynthesis to continue. Background: Light is absorbed by leaf pigments (chlorophyll) which makes electrons within a photosystem moved to a higher energy level. The leaves then make ATP, which reduces NADP to NADPH, and add CO2 into organic molecules. When the leaves go through the process of a light-dependent reaction by being placed in water, oxygen is created through photosynthesis and is released
Fig. 1 illustrates pH changes in the chicken breast samples during the 16 day refrigerated storage period. The initial (day 0) pH of all fillets was 5.81; the pH, however, increased with different trends. Except for day one, the pH values of the control group were significantly different (p < 0.5) from those of other groups. Additionally, the mean of A-L 6 sample was higher than that of the control A, A-l 2 and A- l 4 groups (not significantly, p > 0.05) on days 4 and 8. pH values of chicken fillets (ranging from 5.72 to 6.13 during 16 days) were similar to those reported by Silva et al.
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.
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. It occurs in plants, algae and specified bacteria (prokaryotes). Photosynthesis is the process where plants, algae, and bacteria convert light energy into chemical energy.

2. Why is methane so important? : Fortunately, methane concentrations in the atmosphere are 200 times lower than concentrations of carbon dioxide. On the contrary, concentration of CH4 has increased by 150% since pre-industrial times compared to only 20% and 40% for N2O and CO2, respectively. As a greenhouse gas, methane is 20 times more potent than carbon dioxide, trapping much more heat (IPCC, 2013).
The product of light dependent reactions is oxygen, which they release some into the air and use some for cellular respiration. In light independent reactions, also referred to as the Calvin Cycle, the ATP and NADPH created in the light dependent reactions are used to create glucose. With the glucose they produce, they transform it into energy, for growth, through cellular
They harness their energy form the sun to carry out photosynthesis (Miller and Levine) However, other things are needed to do photosynthesis as well. Carbon dioxide and water are the key components to process photosynthesis. Chloroplast makes photosynthesis happen. They are organelle, or a specialized structure that performs important task in the plant cell. Cell in the plants co-operate to help
