    • 3 Pages

    explain to you why photosynthesis is bad while helping Earth too. I will be giving you a few reasons to explain that photosynthesis is important. So even though photosynthesis can kill the plant‚ photosynthesis is important‚ because it helps grow food for omnivores and herbivores. Photosynthesis grows plants and trees‚ which produce clean‚ fresh oxygen. Photosynthesis helps us living organisms with lungs breathe. It helps us when plants go through the process called photosynthesis. During this process

    Photosynthesis is a crucial energy conversion process that occurs in the chloroplasts of eukaryotic cells. The rate of photosynthetic activity holds importance in environmental‚ horticultural and agricultural situations. (Boardman‚ N.K. 1977). Pigments in the chloroplasts thylakoid membrane absorb the electromagnetic radiation from a light source and release an electron into the electron transport chain. DCPIP’s chemical ability to favourably accept electrons‚ and undergo a colour change from

    Truesdell AP Biology Period 5 2 October 2013 CHAPTER 7 STUDY GUIDE AN OVERVIEW OF PHOTOSYNTHESIS Autotrophs are plants that can feed themselves by making their own food. Photo-autotrophs are organisms that produce organic molecules from inorganic molecules using the energy of light. Producers are when plants make their own organic molecules. A redox reaction is oxidation and reduction. Photosynthesis takes water and carbon dioxide to make glucose and oxygen. Cellular respiration takes glucose

    Photosynthesis is process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose. In so doing‚ photosynthesis provides the basic energy source for virtually all organisms. An extremely important byproduct of photosynthesis is oxygen‚ on which most organisms depend. Photosynthesis occurs in green plants‚ seaweeds‚ algae‚ and certain bacteria. These organisms are veritable sugar factories‚ producing millions of

    How does the Wavelength affect the Refractive Index? The aim of this experiment is to investigate the relationship between the refractive index and the wavelength. We will be testing 5 different wavelengths: 630nm (red)‚ 570nm (yellow)‚ 532nm (green)‚ 445nm (blue) and 405nm (violet). Figure 1 Figure 1 What is the refractive index? The refractive index is the measurement of how hard it is for light to pass through a certain substance‚ thus affecting the speed of light. By knowing the

    Abstract: Two parts of this lab were performed involving photosynthesis and cellular respiration. The first part of the lab consisted of cutting out spinach leaf disks with a straw and then putting them into syringes containing an infiltration solution and sodium bicarbonate. Then the syringes were place under the presence of light and watched as certain disks floated. This part of the lab consisted of watching photosynthesis take place. Then for the second part of the lab we tested cellular respiration

    Practical: The Effect of Concentration on Reaction Rate Aim: To use a simple reaction between sodium thiosulphate and hydrochloric acid to discover concentration this determines how fast chemical reactions occur. Independent Variable: Concentration of hydrochloric acid (%) Dependent Variable: Time taken for chemical reaction to take place (sec) Hypothesis: My prediction is that the increased concentration of the thiosulfate will in turn lead to an increase in the rate of reaction.
