Title: Effects of Light on Photosynthesis Introduction: Photosynthesis is the complex process by which carbon dioxide and water are used to make carbohydrates by using light energy in green plants. The objective of this experiment is to measure the rate of photosynthesis Hypothesis: The petri dish that is exposed to the most light and with the NaHCO3 solution will have the best results and the petri dish that is kept in the dark will have the poorest results. Material and Methods: 1. Get 4

Light is everywhere in our world. We need it to see: it carries information from the world to our eyes and brains. Seeing colors and shapes is second nature to us‚ yet light is a perplexing phenomenon when we study it more closely. Here are some things to think about: Our brains and eyes act together to make extraordinary things happen in perception. Movies are sequences of still pictures. Magazine pictures are arrays of dots. Light acts like particles—little light bullets—that stream from the

The Effect of Different Colored Light on Plant Growth Results I measured each plant on days 7‚ 9‚ 11‚ 13‚ 15‚ 20‚ and 32‚ after planting. The plants under the green cellophane grew the most in every measurement. The biggest growth spurt for the plants under the green cellophane was from day seven to day nine. By day 13‚ the plants under the purple and red cellophane started to grow at similar rates as compared with those under the green cellophane. By day 32‚ the plants underneath the green

Abstract: Two parts of this lab were performed involving photosynthesis and cellular respiration. The first part of the lab consisted of cutting out spinach leaf disks with a straw and then putting them into syringes containing an infiltration solution and sodium bicarbonate. Then the syringes were place under the presence of light and watched as certain disks floated. This part of the lab consisted of watching photosynthesis take place. Then for the second part of the lab we tested cellular respiration

wavelength of visible light affects the rate of growth of aquatic plants Different wavelengths of light will effect to rate of photosynthesis. I will test this by exposing the pondweed to different wavelengths of light to see how it reacts. Method I will do this by passing white light through a filter. The filter will remove all unwanted wavelengths of light leaving the plant exposed to only the desired wavelength of light. I will use three different wavelengths of light 750nm (red)‚ 650nm

throughout my experiments‚ so that temperature would not have an effect on my results. This would help me obtain more reliable and accurate results. Also‚ I made sure that I was drawing the solution up in the pipette beforehand‚ so that I could put it into the cuvette at exactly 30 seconds. This would make my results more accurate‚ as the solution would be put into the cuvette at precisely 30 seconds and so time would not have an effect on my results. I also used separate pipettes to measure out the

Sugar – All Sweetness and Light? Sugar in all its forms is officially a simple carbohydrate. This means the body will convert is into glucose which is then available as energy. Then it gets less simple. Depending on the type of sugar used our health will be impacted rather differently‚ sometimes bad‚ sometimes very bad depending on using either natural or refined types of sugar. Whereas the usual over use of any sugar is likely to add fat and body weight and also play havoc with blood sugar levels
