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. Calcium helps with plant structure and cell wall development. Calcium also helps with root development. I was looking to see if the increase of nutrients from more developed roots and thicker cell walls would increase the plant's ability to photosynthesize. My prediction was that the calcium would increase the photosynthetic process.
Methods
I followed the procedure for constructing the plants growth chamber, and planting the seeds in the lab manual (Tyler and Cowan 2015). The constant in my plants was; Fafard number 2 potting soil, direct sunlight from sitting on the windowsill, and a constant supply of water. In the experimental plant I …show more content…

You can see the hight difference on graph number three. The chromatography data showed that my experimental plant had a more carotene, chlorophyll a and chlorophyll b compared to my control (graph one). When using the Spectrophotometer to measure the amounts of chlorophyll a and chlorophyll b. For my control I measured the absorption of pigments and got the results of; 0.04,0.03, 0.02. I used the same wavelengths in my experimental and got results of; 0.03, 0.04, 0.05. Comparing my results to the classes control chart I saw that my experimental was closer to the data representing chlorophyll a (graph

    In this lab experiment the effects of plant growth and the pattern of plant growth in a lima bean plant had been eye opening. Using different liquids had a different outcome on each plant. the different types of nutrients and PH level in each liquid played various roles in the development and growth of each plant. the plant that had been exposed to sprite and milk showed a effective growth and decay starting from day 5. An incredible 3.2 cms was the growth for the plant which was exposed to pond water and on day 5 the plant that was exposed to the liquid of naturel 2% milk showed a decrease of .2 cms.

    Carly Crabtree Period 4 Accelerated Biology 11/20/15 Photosynthesis in Greenhouses Farmers use their knowledge about photosynthesis to increase crop growth every year. Greenhouse conditions are more easily controlled, rather than the air outside. Changing certain variables in the process of photosynthesis can change the outcome of the crops. One variable that farmers change is the temperature.

    In the above hypotheses, the research done previous to the lab supported the alternate hypotheses for the colored lights in relation to the dim lights, and the null hypothesis for the experiment in which both sides of the chamber had dim light. The dim light on Side B of the chamber would be favored because, in a previous study, D. Melanogaster were exposed to different illuminations, and “their favorite resting, grooming, and feeding places were determined with an infrared-sensitive camera.” Additionally, the study used infrared beams to collect data on the activity levels of the flies during their most active period of the day under different light intensities. Each of these methods demonstrated D. Melanogaster’s preference for dim light occurring “between 5 and 10 Lux” (Rieger et al.).

    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.

    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.

When I moved them into the sunlight I could tell that they had grew more. Some of the plants didn’t grow as fast when I put them in the sunlight, but I think they didn’t grow as fast because of the type of roots and plants they were.

    The null hypothesis, “There is no difference in the concentrations of NaHCO3 and the rate of photosynthetic activity.” is rejected. The alternative hypothesis is supported, that which the greater concentration of NaHCO3, the greater the rate of photosynthesis. Since it was found that the p-value was less than 0.05 in table 1 in all five treatments, this allows the null hypothesis to be rejected. This finding correlates with real life observations of faster rates of oxygen production during lab within the higher concentrations of

Hypothesis If greater and higher concentrations of cobalt chloride are added to each solution then greater amounts of light would be absorbed by each solution. Thus a liner relationship will result in which the absorbance of a substance would be proportional to its concentration, which will be depicted, in a linear graph.

    The purpose of this lab was to test the rate of photosynthesis in cut-out circles of spinach leaves in a solution with only water and a solution with water and carbon dioxide. The hypothesis made for this experiment was that the circles of spinach leaf that were placed in the solution with the carbon dioxide would float to the top more quickly than the circles of spinach leaf that were placed in just water. To test this hypothesis, twenty circles were cut with a hole punch from a spinach leaf in order to have a plant to perform the photosynthesis. Considering plants have oxygen running through their veins, the oxygen had to be taken out of the spinach circles before completing the experiment. To do that, the spinach circles were put into a syringe along with 5 mL of the solution in which they were going to be submerged.

    Next, the amount of seedlings in the tray that expressed a green or white phenotype were both counted. The group observed that there were eleven total seedlings; eight of those seedlings were green and the three remaining were white. The next step in the experiment was to add up the class totals of green to albino seedlings, as shown in table 1. After determining a group phenotype ratio of 8:3 and a class ratio of 42:10, the group questioned what defect the white plants could have that might make the seedlings appear albino instead of green. The students concluded that a lack of chloroplast could explain why some of the seedlings were albino. The lab partners also decided that for a recessive, albino phenotype to be expressed, GG, Gg, and gg had to be the genotypes of the seedlings.

Photosynthesis is the process which a plant gets light energy or sunlight to make food for their selves. Photosynthesis takes place in the chloroplasts. The chloroplast has an organelle inside of it called chlorophyll which has a green pigment, chlorophyll is green because it absorbs red and blue light.
