    Investigation Into The Factors That Affect The Rate Of Photosynthesis In Elodea Investigation into the factors that affect the rate of photosynthesis in Elodea Introduction Photosynthesis is the chemical process, which takes place in every green plant to produce food in the form of glucose. Plants use the suns energy to join together water and carbon molecules to make the glucose, which is sent around the plant to provide food. Cells in the root or stem can use the glucose to make energy, if the...

    Photosynthesis 1. Would you illuminate your house plants with a green light bulb? Why or why not? It would not be a wise choice to put a plant under a green light bulb. The reason for this is that due to the fact that the leaves are green they reflect green light. This shining green light onto the flowers will cause photosynthesis to stop. Since the light is being reflect d, the cells do not get any light. With out light they cannot carry out the everyday of photosynthesis. If the choice was mi...

    Photosynthesis When you and me eat, we find our food. When plants eat, they make their own food and energy. They make their food and energy through a process called photosynthesis. Through photosynthesis oxygen is also produced. Photosynthesis is 'a process in which green plants synthesize carbohydrates from carbon dioxide and water... The reverse of this reaction provides energy for plants, for animals that eat plants, for animals that eat animals that eat plants' for animals that eat animals ...

    Biology Coursework! V Does The Light Intensity Affect the Rate of Photosynthesis The Investigation In this experiment I will investigate the affect in which the light intensity will have on a plants photosynthesis process. This will be done by measuring the bubbles of oxygen and having a bulb for the light intensity variable. Variables The input variable which will be used in this investigation will be the light intensity (this will be a 100 Watt bulb being moved closer and further away from the...

    Photosynthesis Photosynthesis is the most important part of the lively hood of humans and animals. Without photosynthesis we would not be able to receive energy. We should be more appreciate of plants, without them we would not survive. This paper will explain the basic components require for photosynthesis, the role of chlorophyll, how energy is transferred, and photosystem I and II and the most precious product results of photosynthesis. Photosynthesis is a reproductive system that occurs in p...

    Through extensive research, we can come to the conclusion that about 65 million years ago, many kinds of creatures roamed the earth. What ever became of dinosaurs? Where are these creatures today? As a result of various forms of evidence, different theories have been aroused to why these animals no longer exist in this place they once controlled. One presumption that has been brought up about the extinction of dinosaurs is the ever-popular "asteroid theory." Would it be possible that an entire s...
  • Process Of Photosynthesis Energy Light Called
    397 words
    Process of Photosynthesis Photosynthesis is process by which plants containing chlorophyll make carbohydrates from water and carbon dioxide in the air in the presence of light. Green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose. Photosynthesis provides the basic energy source for virtually all organisms. An extremely important byproduct of photosynthesis is oxygen, on which most organisms depend. Photosynthesis has f...

    Problem: How does the amount of light affect the growth rate of a seed? Literature Search: This experiment is only trying to verify the answer since this question has been proven before. Others have also proven that seeds germinate at the same rate at the early stages no matter how much or how little sunlight there is. Once the radicle brakes trough and the plant starts to use photosynthesis to produce energy and grow. Since sunlight is needed in photosynthesis, the plant with more sunlight star...

    The sun is the source of energy for all living things. Plants use solar energy to carry out photosynthesis. Animals that eat the plants also depend on the sun for energy. Even the fossil fuels that are burned came from the sun, in directly, since the living things decayed into fossil fuels used solar energy. A.

  • Chloroplast Rate Of Photosynthesis

    Introduction: This experiment was done to test the hypothesis: Boiling and decrease in light will have negative affects on the rate of photosynthesis in chloroplasts. In this experiment we were told that we would be measuring the rate of photosynthesis. The reduction of a dye called DPIP is a part of the measurement technique. The transfer of electrons during the light-dependent reactions of photosynthesis reduce DPIP, changing it from light blue to colorless. The information on the lab sheet sa...

    Photosynthesis is a biochemical process in which plant, algae, and some bacteria harness the energy of light to produce food. Nearly all living things depend on energy produced from photosynthesis for their nourishment, making it vital to life on Earth. It is also responsible for producing the oxygen that makes up a large portion of the Earth! |s atmosphere. Factors that affect photosynthesis are light intensity and wave length, carbon dioxide concentration, and temperature. Plants are autotrop...

    A Spectrophotometric Analysis of the Absorption of Green Light Versus Red Light Absorption in Spinach Leaves The goal of the experiment was to determine if green light had less ability to absorb than red light in spinach leaves. This was done by separating the photosynthetic pigments (chlorophyll a, chlorophyll b, carotene and xanthophylls) from one another using paper chromatography. The separated pigments were then analyzed for their absorption spectrum using a. When the data was graphed it cl...

    By Gerard Chretien Biology Photosynthesis: Energy from the Sun Identifying Photosynthetic Reactants And Products A. The water for photosynthesis in land plants comes primarily from the soil and must travel from the roots to leaves. B. Carbon dioxide is taken in, and water and O 2 are released, through tiny openings in leaves, called stroma ta. C. Light is absolutely necessary for the production of oxygen and carbohydrate. The photosynthetic production of oxygen by green plants is an important s...

They do this by a process called photosynthesis. For photosynthesis to occur they need sunlight energy. This energy is absorbed by a green pigment called chlorophyll, which is mainly found in the leaves. This energy then combinEs with water molecules (from the soil) and carbon dioxide (from the air).

    Colours Chloroplasts contain several different pigments the majority of which are chlorophyll a and chlorophyll b. Both of these types of chlorophyll absorb similar wavelengths of light, but chlorophyll a absorbs a slightly higher wavelength than chlorophyll b. Neither chlorophyll absorbs much light in the green region of the spectrum thus making it appear green. This can be plotted onto a graph (fig 1. 1). This graph is called the Absorption Spectrum. The Absorption Spectrum is very similar in...
  • Oxygen Bubbles Photosynthesis Light Test

    Classwork Wednesday, 08 October 2003 Photosynthesis Exploration Aim - To see how changing the light intensity affects the rate of photosynthesis. Prediction - I predict that as the amount of light is reduced (lamp steadily being moved away), the rate of photosynthesis will slow down. Consequently the nearer the lamp is to the plant, the more oxygen bubbles are produced. Hypothesis - The reason I predicted that if the amount of light is reduced the rate of photosynthesis will slow down is because...

    Biology Coursework: Photosynthesis The aim of the experiment was to investigate a factor that would affect the rate of photosynthesis in a Canadian pondweed plant. Canadian pondweed is used because it has an unusual quality of giving off bubbles of oxygen from a cut end and it's easy to see and monitor / count the bubbles in water. It was decided to use light intensity as the experimental variable, different paper will be wrapped around the beaker containing the pondweed and different amounts of...
