The effect of different wavelengths of light on photosynthesis rate in spinach leaves Abstract: This experiment was performed to test the effect of different wavelengths of light had on photosynthesis. According to the results gathered we can say that if two plants are put under different lights‚ one green and one a normal light‚ that the plant under the normal light will perform photosynthesis at a higher rate than the plant under the green light. This experiment is important because it shows

3/22/2013 Lab 1- The scientific method In this lab I am learning about the steps of the scientific method and how it can be applied to daily life. In my first exercise I analyzed data presented to me in a table (table 2) on fish population in relation to the amount of dissolved oxygen ( ppm ) in the water. The patterns indicate that when more dissolved oxygen (ppm) is present in the water‚ the number of fish observed increases. In developing a hypothesis for this theory‚ I have decided that if

Aquaponics system is a food production system that combines conventional aquaculture‚ raising aquatic animals such as snails‚ fish‚ crayfish or prawns in tanks‚ with hydroponics cultivating plants in water in a symbiotic environment. In normal aquaculture‚ excretions from the animals being raised can accumulate in the water‚ increasing toxicity. In an aquaponic system‚ water from an aquaculture system is fed to a hydroponic system where the by-products are broken down by nitrogen-fixing bacteria

BIO 110 Lab 1 The Scientific Method Exercise 1 1. Based on the information in Table 2‚ the patterns I observed were that were 2ppm of Dissolved Oxygen added each time and there was 1 fish less than the amount of Dissolved Oxygen‚ then 4 fish less‚ then 3 fish less‚ then 4 fish less‚ than 5 fish less. I think that the fish can handle the amount of Dissolved Oxygen to an extent then the population falls‚ but then starts to build back up. I also think that if the population is a bigger number

Methods for studying cells in the lab Centrifugation A centrifuge is a device for separating particles from a solution according to their size‚ shape‚ density‚ viscosity of the medium and rotor speed. Centrifugation can be used to separate cells from one culture or to isolate an organelle from the rest of the cell. The process relies on speed; the faster and longer the particle is centrifuged‚ the smaller the particles are that will be separated. Separation occurs by causing the larger particles

investigating does the temperature affect how quickly the particles diffuse to an even concentration throughout the water‚ we are going to do this experiment by using food coloring to see how quick the food coloring diffuse in hot water and cold water. Materials: • • • • • • • • One beaker Hot plate Ice Water Food coloring Thermometer Timer Eye dropper Hypothesis:I think the food coloring will spread faster‚ because the particle in the hot water have more kinetic energy than the cold water‚ so it will

Photosynthesis is process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose. In so doing‚ photosynthesis provides the basic energy source for virtually all organisms. An extremely important byproduct of photosynthesis is oxygen‚ on which most organisms depend. Photosynthesis occurs in green plants‚ seaweeds‚ algae‚ and certain bacteria. These organisms are veritable sugar factories‚ producing millions of

The point at which 50 percent of the leaf disks are floating will be you point of reference for future investigations Using the graph the estimated time that roughly 50% of the leaf disks were floating on the surface was around the 10th minute. At the 10th minute our number rose up to

Chloroplasts and Photosynthesis All animals and most microorganisms rely on the continual uptake of large amounts of organic compounds from their environment. These compounds are used to provide both the carbon skeletons for biosynthesis and the metabolic energy that drives cellular processes. It is believed that the first organisms on the primitive Earth had access to an abundance of the organic compounds produced by geochemical processes‚ but that most of these original compounds were used up billions
