purpose of this lab was to investigate whether veins affect photosynthesis rate. It was predicted that having veins would decrease the rate because chloroplast might be less frequent due to the vascular tissue. For this experiment‚ 4 groups were set up: veins and no veins in CO2 solution‚ and veins and no veins in distilled water‚ the distilled water groups served as controls. These 4 groups were placed under a light bulb in order for photosynthesis to occur. No disks experience movement in the first 7

Period G Interspecific and Intraspecific Plant Competition Abstract A study was conducted to address the problem of interspecific and intraspecific competition among wheat and mustard plants. It was hypothesized that increasing the plant density‚ and therefore increasing intraspecific competition‚ would negatively impact the plant biomass. It was also hypothesized that interspecific competition would have a stronger negative effect on the plant biomasses. This was tested by planting varying

light Introduction In November 2011‚ Hong Kong Disneyland and Microsoft created a new game which is Kinect: Disneyland Adventures games. This is marketing-mix. Kinect Disneyland Adventures is a video game published by Microsoft Studios on Kinect for Xbox 360‚ there has recreated a large amount of the Disneyland theme park‚ with themed games in place of many of the rides. Also‚ there are various characters such as Winnie the Pooh‚ Cinderella‚ Daisy Duck and Donald Duck and so on. The target audiences

Coffee Bean‚ Inc. (CBI)‚ is a processor and distributor of a variety of blends of coffee. The company buys coffee beans from around the world and roasts‚ blends‚ and packages them for resale. CBI currently has 40 different coffees that it sells to gourmet shops in one-pound bags. The major cost of the coffee is raw materials. However‚ the company’s predominately automated roasting‚ blending‚ and packing process requires a substantial amount of manufacturing overhead. The company uses relatively little

EXPERIMENT 5 REDOX TITRATION: TITRATION USING SODIUM THIOSULPHATE Objectives 1. 2. To prepare a standard solution of potassium iodate for use to determine the concentration of sodium thiosulphate solution accurately. To acquire the proper techniques of carrying out a titration. Introduction Redox titrations using sodium thiosulphate as a reducing agent is known as iodometric titration since it is used specifically to titrate iodine. The reaction involved is: I2 + 2Na2S2O3 I2 + 2S2O322NaI + Na2S4O6

Porterfield | 11/26/2012 | Biology Lab 180 Section C | Introduction The purpose of this experiment was to practice applying the use of the scientific method. One of the main steps in the scientific method is forming a hypothesis. Increasing fertilizer is expected to increase rate of growth and increase number of leaves. Materials and Methods The materials used included seeds of Wisconsin fast plants Brassica rapa‚ Styrofoam planting quads‚ potting soil‚ 14- 14- 14- NPK fertilizer beads‚ labeling

Design Experiment to investigate the effect of the concentration of Sodium Hydrogen Carbonate on the rate of photosynthesis using Cobomba plant. Aim: The aim of the experiment is to investigate the effect of the concentration of Sodium Hydrogen Carbonate (NaHCO3) on the rate of photosynthesis using a Cobomba plant. Hypothesis: As the concentration of NaHCO3 increases the rate of photosynthesis of the Cobomba plant should increase‚ as there is a greater presence of a carbon dioxide‚ obtained

The winged bean (Psophocarpus tetragonolobus) is a twining‚ perennial herbaceous legume which can climb to 3-4 meters (Kantha and Erdman‚ 1985). As a leguminous plant‚ winged bean can be used in almost all parts of the plant. Fruit‚ leaves‚ flowers‚ bulbs and seed are edible and contain high protein and oil (Kotaru et al.‚ 1987; Dwiani et al.‚ 2014). The mature‚ dry seed is the most nutritious part of the winged bean. Their outstanding nutritive quality is based‚ above all‚ on their high protein

Carnivorous Plants In a world where plants are at the bottom of the food-chain‚ some individual plant species have evolved ways to reverse the order we expect to find in nature. These insectivorous plants‚ as they are sometimes called‚ are the predators ‚ rather than the passive prey. Adaptations such as odiferous lures and trapping mechanisms have made it possible for these photosynthesizers to capture‚ chemically break-down and digest insect prey (and in some cases even small animals.) There

AP Biology Photosynthesis Lab Bethany Boyer Due 11/12/14 Lab Write-Up Questions First Experiment 1) The independent variable in this experiment was the presence of CO2 (carbon dioxide). The dependent variable was the speed at which the leaf disks started to float. 2) In the leaf tissue‚ the bicarbonate and light are combining to carry out photosynthesis. This will cause oxygen to collect in the leaf tissue‚ causing it to rise. 3) If we were to boil the leaf disks‚ the reaction would most likely
