Advanced Biology Photosynthesis Lab Report By Cheryl G11 Introduction & Background Photosynthesis is the process by which light energy is converted to chemical energy. It occurs within each chloroplast in most of the green plants, and Carbon dioxide is one of the main components of this process. Plants use photosynthesis to produce their own food (glucose), some water and the oxygen that we need. The overall balanced equation is: 12 H2O+ 6 CO2 → 6 H2O+ C6H12O6 + 6 O2 Sunlight energy Where: CO2 = carbon dioxide H2O = water Light energy is required C6H12O6 = glucose O2 = oxygen Purpose Through this experiment, we want …show more content…

Pour 100 ml into each plastic cup, then one mixes with baking soda, another one with liquid soap. Remember to label on each cup “CO2” and “ soap ”. Show in Figure 1 & 2. Figure 1. Measure the water Figure 2. Label on the cup 3. Cutting leaf disks Using a hole punch, cut 5 or more uniform leaf disks for each cup. Avoid major leaf veins. It’s better to choose the leaf that has smooth surface. See Figure 3. Figure 3. Example picture of cutting leaf disks 4. Infiltrate the leaf disks and solution into each syringes. a. Remove the piston or plunger and place the same amount of leaf disks into both syringe barrel. Replace the plunger being careful not to crush the leaf disks. Push on the plunger until only a small volume of air and leaf disk remain in the barrel. Show in Figure 4. Figure 4. Example picture of putting the disks into the syringe. b. Pull in some volume of solution from the cup into syringe. One for carbon dioxide, another one for soap. Show in Figure …show more content…

The experiment that we conducted were successful in exemplifying the effect of the presence of CO2on the rate of photosynthesis in leaf disks. As predicted, the leaf disks in the CO2 Cup were quicker to float to the top of the water. According to the data, the disks inside the CO2 Cup (higher concentration of carbon dioxide) have floated up continuously after 17 minutes, but disks in the Soap Cup (lower concentration of carbon dioxide) haven’t even started to float during the same period of time. But this doesn’t mean that the disks in the Soap Cup won’t be able to float up, they just need a lot more time to go through the photosynthesis process and then produce the

Transitioning between photosynthesis and respiration : CO2 cuts into carbon and oxygen, some of the oxygen is then released and the carbon mixes with H20. If it was mad and balanced, the effect of carbon and water will also affect glucose. This is called photosynthesis. Plants take the water and CO2 in order to make food (glucose) which sets the oxygen free.

The most important result from this experiment is that it suggested that the increase of Carbon Dioxide, will drastically increase the growth mountain maple in the covered (from the sun) parts in a forest, in the meantime any increase in the temperature of the soil will nullify the increase of light, as we know is to be the main ingredient for photosynthesis. 5.

According to the group data, the hypothesis was proven correct; the leaf circles in the carbon dioxide solution surfaced more quickly than the leaf circles in the water did. This occurred because carbon dioxide is a reactant in photosynthesis, therefore the more it is present the more successful the reaction is going to

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.

Introduction: Photosynthesis is a process used by plants and specific types of bacteria in order to make their own food source from sunlight to chemical energy. It is mainly occurred within the leaves of the plant. The reaction requires light energy in order for it to be absorbed by chlorophyll. During the reaction carbon dioxide, water is converted into glucose and oxygen as shown below: Figure 1 (photosynthesis uses light energy to convert carbon dioxide into a carbohydrate) (The Chemical Equation of Photosynthesis. 2018, Accessed 16 March 2018) There are two types of photosynthetic processes; one includes oxygenic photosynthesis, which is most common and demonstrated through plants, algae and cyanobacteria while the other one is an-oxygenic photosynthesis.

The carbon is used in the photosynthesis formula Carbon dioxide (CO2) + Water (H2O) + Energy ➡Glucose (C6H12O6) + Oxygen (O2) to create food such as glucose. Photosynthesis extracts carbon from both land and water plants. The water plants take the carbon dioxide that is found in water whereas the land plants take it from the air.
