determine the effects of sugar on photosynthesis in Elodea. Sugar water with Elodea‚ water with Elodea‚ and water (control) are used to test for photosynthesis. Five drops of sugar water were added to sugar water with Elodea beaker. The three beakers were left under normal light for photosynthesis to occur. After 60 minutes‚ NaOH solution was added to each beaker to test the volume of CO2. The result shows that both Sugar water with Elodea and water with Elodea consumed the CO2 in same rate‚ which means

Photosynthesis is the process by which light energy is used to convert inorganic compounds into organic substances with the subsequent release. There are many factors which can have an effect on the process of photosynthesis; in this laboratory experiment‚ the focus lies on carbon dioxide (CO2) availably and its effect on photosynthesis. By understanding the component that affect the rate of photosynthesis‚ one can do work to try and increase the rate of photosynthesis. The purpose of this laboratory

Investigation 5: Photosynthesis Problem: If the leaf disks are treated in a way you know increases the net rate of photosynthesis‚ should they start to float faster or slower? Why? Hypothesis: If the leaf disks were bathed in a red light source‚ then the rate of photosynthesis would increase than leaf disks that are bathed in a regular light source because chlorophyll absorbs red pigment and reflects green pigments. Therefore‚ shining a red light source onto the leaf disks would cause them

Lab Report: Understanding Photosynthesis Gen Biology Lab Abstract: This lab was called photosynthesis: understanding photosynthesis. It is a highly complex process that needs to be broken down in many steps to understand how it works. This lab covers the big components in photosynthesis including carbon dioxide intake‚ light consumption‚ and varying pigmentation. Introduction: Photosynthesis is a huge concept to learn and understand in the field of biology. Plants have their own special

the cycling of carbon through both cellular respiration and photosynthesis of a plant” we devised a hypothesis that states‚ If we place the two test tube‚ one with carbonated water and the other regular water‚ with the Elodea inside a dark environment it will perform cellular respiration as it will not receive enough light energy to perform photosynthesis. From the result of our experiment we found that the test tube with tap water and Elodea changed from its original color of Blue to a more faded shade

Lab Report: Photosynthesis Name: Purpose of this Lab What is the goal of this lab? What question are you trying to answer‚ or what problem are you trying to explain? In this lab I will perform experiments to explain photosynthesis. I will answer questions like what does photosynthesis do and how does photosynthesis work? Hypothesis After reading the lab instructions (but before starting the lab) record your best educated guess about what will happen in the experiment. Explain

Introduction: Photosynthesis is a process to which some autotrophs such as plants produce their own food. It has two stages or reactions light-dependent and light-dependent reactions. The light dependent reactions are the first stage‚ where energy from sunlight is captures in Photosystem 2 and then 1‚ the electrons generated in Photosystem 1 then moves along the electron transport chain. The moving of electrons causes a hydrogen ion gradient that is used in the final step to produce ATP‚ by the

Lab: Cellular Respiration in Yeast Lab Report Form Your Name: Katlin Moore “What do you think? – What do you know?” Questions: In this lab‚ we will investigate the effect of sucrose concentration on the rate of cellular respiration in yeast. Under specific conditions‚ yeast will convert sucrose into glucose and then use this glucose in cellular respiration. Yeasts have been used by humans in the development of civilization for millennia. What is yeast? How have humans used yeasts?

CO2 Lab Report Intro Alka-Seltzer tablets are used to treat cold/flu symptoms as it produces CO2 when dissolved in water. The goal of this lab is to calculate the amount of NaHCO3 is needed to produce enough CO2 gas to fill the room. Experimental One Alka-Seltzer tablet was weighed on the analytical balance. Then a piece was measured out to be between 0.21 and 0.28 grams. 500mL of distilled water was added to a 600mL beaker. 80mL of water was mixed with 20mL of 6M HCl in a 150mL beaker. A

Name Biology-Honors Teacher December 6‚ 2012 Photosynthesis Lab 1. Introduction: Light dependent reactions are the first phase of photosynthesis. It requires light to happen and happens in the thylakoid membrane in a chloroplast. The light energy is absorbed from the sun and converted into chemical energy. Which is then stored temporarily in ATP and NADPH. Hypothesis: I predict that the wavelength intensity will affect the rate of photosynthesis more than light intensity will. 2. Data:
