The Effect of Light Intensity on the Rate of Photosynthesis of Elodea in the Aquarium Aim The aim of this experiment was to investigate the relation between the light intensity and photosynthesis rate of Elodea in an aquarium using a simulator. Background Photosynthesis is metabolic pathway in which plants use carbon dioxide and water to produce glucose by the aid of light energy from the sun. Light energy is usually absorbed by chlorophyll; a green pigment in plants. The equation of…

A niche is the role or part that an organism plays in it’s specific ecosystem or habitat. An example would be a sunflower. The sunflower inhabits a grassy area and the role that it plays in the area is that it is the producer that gives off energy to the other trophic levels that also inhabit the grassy area. (1) In total, I found 7 different kinds of bacteria in the columns. (2) -In the Controlled Column, I found Cyanobacteria (5) along the top of the column. This bacteria causes the lighter…

Plants get mass from the air, specifically carbon dioxide. The results from both VonHelmont's experiment and the radish seed experiment support this idea. In VonHelmont’s experiment, the plant gained 164 pounds in 5 years while the soil only lost 2 ounces in weight.These results reveal that a plant does not receive its mass from soil. The roots of the plant absorbed water from the soil in order to photosynthesize causing the soil to lose 2 ounces overtime. In the radish seed experiment, the…

Chloroplast (Plant cells only) - Small oval structure containing chlorophyll giving the chloroplast a green pigment. Chloroplast uses the sun’s energy to create food for the plant, this is known as photosynthesis. Cell wall (Plant cells only) - Provides structure and protection to the cell in the form of an outer layer. This organelle lets H2O, CO2, and O2 pass through it. One large vacuole (Plant cells only) - Large sac filled with fluids. The vacuole in a plant cell stores, large amounts…

The purpose of this experiment is to determine the optimal absorption of different solutions, specifically the Chloroplast extract (chlorophyll a and chlorophyll b) and Fast Green solution using the technique of spectroscopy. The following graphs and data will be used to identify the concentration of the given unknown solution #294. Spectroscopy is a process whereby a spectrophotometer is used to determine the absorbance levels of different solutions at different wavelengths (Pettruci et al.,…

for the activity of a chloroplast electron transport chain. The two choices that were available for us to investigate was broccoli and pea seedlings. Our group was nominated to utilize 20 grams of broccoli florets to find fractions that composed of an abundance of chloroplast. Project 1 had 3 parts to it; this consists of fractionation of cell homogenates, assay for chloroplast-specific electron transport chain activity, and testing factors that affect activity of the chloroplast electron…

you?” called out Chloroplast, “ATP can you tell me where they are?” “Aren’t you the one that said that that’s cheating a few minutes ago?” replied ATP. “Ugh, Fadh, a little help here?” “Sorry, no can do. Don’t make rules in the first place if you aren’t willing to follow them yourself.” He replied nonchalantly, as he flipped through a new issue of Photosynthesis Times. “Don’t you get tired and feel like throwing in the towel sometimes?” hinted Glycolysis. “Yeah.” sighed Chloroplast. “No, that…

Hypothesis Can chloroplasts be identified with light? And if so, which test tube would the light be most helpful to? We were interested in seeing where the chloroplasts ended up by adding an isolation buffer and DCIP or water. Our hypothesis was that the chloroplasts were going to be identified with the use of light. We also believed that the chloroplasts were going to be in the P2 test tube. We knew that the chloroplasts weren’t going to be in P1. We knew this, because the chloroplast isn’t a…

Chloroplast are found in plants, they are responsible for the metabolism of energy to produce food for plants by breaking down Carbon dioxide, water and sunlight through a process called Photosynthesis. Once Carbon Dioxide enters a plant through stomata pores in a plant, water is absorbed through the roots of a plant and sunlight captured by chlorophyll pigments inside the chloroplast which is actually inside the thylakoids. It 's the russian doll complex., it is within the chloroplast that…

It could be compared to a person, a project, another kind of cell, and basically anything else. So today we will be comparing it to a food factory for many different reasons that you will soon read below. First, I will be comparing chloroplast to a factory. Chloroplast is like a food factory because they both produce food helping the community of either…
