Conclusion I predicted that if the decolorization of DPIP is caused by photosynthesis and not cell respiration and spinach extract containing chloroplasts and mitochondria is incubated with DPIP‚ then the rate of DPIP decolorization should be higher if in bright light verses dark light because DPIP is reduced by photosynthesis and not by the mitochondria or any other cellular function. If DPIP was only decolorized by chloroplasts‚ then the percent transmittance of chloroplast suspensions would be

measured to determine the rate of photosynthesis. This experiment was set up to discover how different wavelengths of light affect the rate of photosynthesis in a spinach‚ DPIP‚ phosphate solution. I proposed that the spinach‚ DPIP‚ phosphate solution under no filter‚ and therefore exposed to all light will have a highest percent orange light transmittance and a highest rate of photosynthesis. The solution under the red filter will have the next highest rate of photosynthesis‚ then the solution under the

The Effect of Temperature on the Rate of Yeast Respiration Abstract Carbon dioxide is a waste product of yeast respiration. A series of experiment was conducted to answer the question; does temperature have an effect on yeast respiration? If the amount of carbon dioxide is directly related to temperature‚ then varying degrees of temperature will result in different rates of respiration in yeast. The experiment will be tested using yeast and sugar at different water temperatures. I

However‚ conceptually it will be a little easier because the concepts learned in Chapter 9—namely‚ chemiosmosis and an electron transport system—will play a central role in photosynthesis. 1.

Cyanobacteria’s big advantage over other early life forms was their ability to perform photosynthesis. They contain a blue photo reactive pigment that can absorb the energy from the sunlight and use it to produce nutrients for the cell. During this process‚ water molecules are broken down into oxygen and hydrogen atoms which are then released in the air. In the very early days of life‚ Earth was populated only by anaerobic bacteria that didn’t need oxygen to survive. When cyanobacteria first made

Photosynthesis The leaves are the part of a plant where most photosynthesis takes place. If you cut a leaf in half and look at the cut end‚ it would look like this: Key: 1. Waxy cuticle: this gives the leaf a waterproof layer‚ which lets in light. 2. Upper epidermis: provides an upper surface. 3. Palisade cells: contain chloroplasts. 4. Spongy mesophyll: collection of damp‚ loosely packed cells. 5. Lower epidermis: layer of cells on the lower surface. 6. Air

Effect of Extreme Temperatures on the Rate of Photosynthesis 2. Jeffrey Xia 2. Abstract A previous lab in which we conducted‚ tested whether or not the light intensity had an effect on the rate of photosynthesis. We concluded that light intensity did possess an effect on the rate of photosynthesis – the closer the experimental plant units were to the light source‚ the more experimental plant units exhibited the effect of gas exchange in photosynthesis. Therefore‚ in this lab‚ we desired to test

The atmosphere is full of different smells‚ it all depends where you are locate. I live here on William Paterson campus and I smell a lot of different odors. If you go into the diner hall‚ where the food is bein starved you get a smell of different kinds of food. The smells can vary from pizza to burgers or pasta and sometimes in the morning it smells like waffles. When you arrive in my dorm building‚ it does not have much of a smell beside when they mop the hall way. Sometimes the hallway smells
