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
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
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
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
For this lab, I will carry out an experiment to determine which colors of the light spectrum cause the most plant growth. red light green light violet light yellow light blue light I have 3 different types of plant seeds I will plant under each light spectrum to be able to draw conclusions from multiple pieces of data. Seed: Spinach Seed: Lettuce Seed: Radish The data I collect will either support or contradict my hypothesis. Assuming that all
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
the amount of oxygen dissolved in plant water? Purpose: The purpose of this lab is to determine which type of water (distilled, with snail, plant, with snail and plant) produced the most dissolved oxygen and which produced the least. Hypothesis: If there is a snail in the plant water, then there would be more dissolved oxygen than in distilled water because snails release carbon dioxide that can be used for photosynthesis from the plants. Materials: Test tube (1) Beaker (1) Snail (1) Distilled Water
Marissa Aguilera, Jenine Hamed, Jessenia Torres Biology 1441 Sec 038; Professor Holmes; October 3, 2014 Elodea grows in freshwater and in this experiment the plant will be placed in a saltwater environment to test the efficiency or deficiency of photosynthesis and aerobic respiration. One of the plants was placed in a 75 mL diH2O solution while the other plant was placed in a 75 mL saltwater solution. There were two other beakers, one with 75 mL diH2O and the other with 75 mL saltwater, with no plants
The Purpose of this lab was to observe how osmosis and diffusion happen in selectively permeable membranes. Diffusion is the movement of molecules from a high area of concentration to a low concentration [1]. Osmosis is the result of diffusion of water across a membrane. Diffusion mainly occurs in gas or liquid molecules. Osmosis occurs when the outside of the cell has a higher water concentration than the cell itself. Diffusion helps exchange gases during photosynthesis, which then creates energy
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
