    All green parts of a plant have chloroplasts. However, the leaves are the major site of photosynthesis for most plants. There are about half a million chloroplasts per square millimeter of leaf surface. The color of a leaf comes from chlorophyll, the green pigment in the chloroplasts. Chlorophyll plays an important role in the absorption of light energy during photosynthesis. Chloroplasts are found mainly in mesophyll cells forming the tissues in the interior of the leaf. O2 exits and CO2...

  • Photosynthesis - 273 Words
    Photosynthesis is a process through which plants and some certain types of bacteria get energy from the sun's UV-rays and use it to create and store sugar that is transformed into ATP by cellular respiration later on in the process. In plants, this process takes place in chloroplasts, which concentrate in the mesophyll cells, with the help of chlorophyll, the green pigment, which is directly involved in photosynthesis. It is important to understand that we see leaves green simply because the...

    Photosynthesis (pron.: /foʊtoʊˈsɪnθəsɪs/; from the Greek φώτο- [photo-], "light," and σύνθεσις [synthesis], "putting together", "composition") is a process used by plants and other organisms to convert the light energy captured from the sun into chemical energy that can be used to fuel the organism's activities. Photosynthesis occurs in plants, algae, and many species of bacteria, but not in archaea. Photosynthetic organisms are called photoautotrophs, since they can create their own food. In...

    Photosynthesis Light reaction of photosynthesis occurs on the thylakoid membrane inside of chloroplast. Light energy excites electrons that are carried down an electron transport chain. The purpose of this is to give the hydrogen ions the energy they need for active transport. It is active because the concentration of hydrogen ions outside the thylakoid is less than inside. Now that there is a high concentration of hydrogen inside the thylakoid, ATP synthase can occur. As the hydrogen go...

    Evidence of Photosynthesis Photosynthesis is the process during which a plant’s chlorophyll traps light energy and sugars (glucose) are produced. In plants, photosynthesis occurs only in cells with chloroplasts. Water (H2O), carbon dioxide (CO2) and light energy are required. The light energy is absorbed by the green pigment, chlorophyll, and is converted into chemical energy, which causes the water drawn from the soil to split into molecules of hydrogen and oxygen. The hydrogen combines with...

    Photosynthesis Essay During the Light Dependent Reactions, activity occurs within the thylakoids of the chloroplast. NADP+ accepts two high energy electrons and an H+ ion and then converts into NADPH. This process ultimately traps some of the sunlight in chemical form. Then, NADPH is able to carry the energy it absorbs to the rest of the cell. The reaction produces O2 gas and converts ADP to ATP and NADP+ to NADPH.

  • Photosynthesis and Inner Chloroplast Membranes
    Chloroplast Chloroplasts are the food producers of the cell. This organelle is only found eukaryotic cells. They are only found in plant cells. Chloroplasts contain small pigments called chlorophylls. Animal cells do not have chloroplasts. All green plants you see are working to convert the energy of the sun into sugars. Plants are the basis of all life on Earth. They create sugars, and the oxygen that we breathe. This process is also known as chloroplast. The mitochondria work in the...

  • Process of Photosynthesis Essay Example
    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....

  • Concentration of Carbon Dioxide and Photosynthesis
    Photosynthesis Part 1 The effect of the concentration of carbon dioxide on the rate of photosynthesis An increase in the carbon dioxide concentration increases the rate at which carbon is incorporated into carbohydrate in the light-independent reaction, and so the rate of photosynthesis generally increases until limited by another factor as it is normally present in the atmosphere at very low concentrations (about 0.04%), increasing carbon dioxide concentration causes a rapid rise in the rate...

  • effects of cigarette smoke to photosynthesis
    THE EFFECTS OF CIGARETTE SMOKE TO PHOTOSYNTHESIS Increased Carbon Dioxide Smoke of all kinds, including cigarette smoke, increases the amount of carbon dioxide where it is present (since smoke is itself produced via combustion). Plants use carbon dioxide to make sugars (during photosynthesis). Its increased abundance, therefore, makes it easier for the plant to obtain. Thus, smoking near a plant actually makes it easier for that plant to obtain much-needed carbon dioxide. Hampering...

  • Photosynthesis and Green Light Bulb
    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 reflectd, the cells do not get any light. With out light they cannot carry out the everyday occurrence of photosyntesis. If...

    Both photosynthesis and cellular respiration are the main pathways of energy transportation in organisms. However, the reactants and the products are exact opposites in photosynthesis and in cellular respiration. In photosynthesis, cells take in carbon dioxide (CO2) and water (H2O) by absorbing energy from the sun, and then the cells release oxygen (O2) and store glucose (C6H12O6).
