THE RATE OF PHOTOSYNTHESIS IN SPINACH LEAF DISKS Introduction Photosynthesis is the process in which light energy is converted into chemical energy. Using the energy of light, carbohydrates such as sugars are synthesised from carbon dioxide and water. The name photosynthesis is derived from the Greek words, photo for ‘light’ and synthesis meaning ‘putting together’. Oxygen is also released, as a waste product. Different wavelengths of light are the major factors for photosynthesis. The process
Activity of Pigments on the Rate of Photosynthesis By Rachel Whaley 3/23/15 Yumna Zahid Biology 111, Section 537 Abstract Photosynthesis converts carbon dioxide, water, and light energy into chemical energy (glucose) and oxygen, and serves as the foundation for most food webs. The distance chloroplasts were from a light source was varied and a spectrophotometer measured the rate of photosynthesis in the first experiment. Light intensity and the rate of photosynthesis were directly related. In the
Photosynthesis Assignment Lance Misland Ms T Joshua Marine Biology 1 (MAB150S) 14 September 2015 Introduction: Photosynthesis is the process that primary producers undergo in order to make food for them; they do this by converting light energy into chemical energy, storing it in bonds of sugar. This process occurs in organisms that have chloroplast (plants and some algae), using chlorophyll to capture the light. However, plants only need light energy, CO2 and H2O to make sugar (Biology, 2014)
Discussion: The rate of photosynthesis is dependent on the light intensity and the chloroplasts. Spinach was blended and used in this lab for the chloroplasts. Cuvette one solution was clear with a tint of green, it included phosphate buffer, distilled water, and unboiled chloroplasts. The green colour in the solution was the chloroplasts. No DPIP was added to the solution so therefore the colour did not change. Each time after 6, 13, and 20 minutes in light, the transmittance was adjusted on the
The Effects of Light on the Rate of Photosynthesis Tong Wu October 10, 2014 Lab section 82036: Mondays at 12:00 PM - 2:45 PM Performed and written by: Nayobe Bivins Stephanie Wigmore Abstract The objective of this experiment was to determine the relationship between light and the rate of the photosynthesis of the Elodea plant; that is, to describe the effects of a light source on photosynthesis. To test the effects of light on photosynthesis in this experiment, the Elodea plant was placed under
lower the pH gets, the less duckweed survives. Acidity has an effect on the rate of photosynthesis because the enzymes required in the process of photosynthesis only function properly at a pH of between 6 and 8 (Egle & Brown, 2005). All the solutions in the experiment that had a pH of less than 6 did not allow the duckweed to survive or to be in a good condition, this is because the pH was too low for photosynthesis to take place which resulted in the duckweed dying as it could not obtain the nutrients

Kelley Small Maddie, Gillian, Ally 21 October 2015 Period 5 Photosynthesis and Cellular Respiration Abstract: In this lab, we tested the rate of production and consumption of Carbon Dioxide and Oxygen from spinach leaves in different amounts of light. We tested it one time using a completely dark space and one time using a space with lots of light. In order to calculate the data, we used LoggerPro and BioChambers to measure the gases in fifteen minute intervals. There are four bar graphs, measuring
Photosynthesis Lab Report Abstract- The main purpose and objective of this lab is to determine if the consumption of carbon dioxide requires light or not during the process of photosynthesis. To complete this experiment the negative control is put under two different tests. Placing one test tube with no plant and exposed to light and the other test tube with the plant and no light exposure. Even though light is not required for the consumption of carbon dioxide, the hypothesis was not supported by
INTRODUCTION Photosynthesis is a chemical process in which plants, algae and certain bacteria produce oxygen and glucose using the energy from the sunlight. This process is important for life because of the oxygen and glucose released; these products are used in many life processes. Photosynthesis takes places in a wide variety of organisms and also comes in different forms; these include a form of photosynthesis that does not produce oxygen which is called anoxygenic and the other form which does
