    Cellular respiration and photosynthesis are fascinating‚ complicated‚ and important processes that are essential to life. Cellular respiration exists in animal and plants‚ whereas photosynthesis only exists in plants due to the chloroplast organelle. Cellular respiration starts with glucose‚ and oxygen and the photosynthesis process on the other hand starts off with the absorption of photons of light from the sun.While the end products of cellular respiration are carbon dioxide‚ water‚ and ATP‚ the

    This experiment focuses on the effect of light intensity on the rate of photosynthesis. In simple terms this refers to how the production rate of the products of photosynthesis (oxygen and glucose) will be affected by a light source at different distances. The hypothesis states that “If there is a higher light intensity‚ then more oxygen and glucose molecules will be produced‚ and the rate of photosynthesis will increase.” This hypothesis was accepted. This was determined by counting the number of

    transport of water molecules across a selectively permeable membrane” (Lab Manual 2nd edition). It was hypothesized that osmosis will occur when there is an uneven distribution of solute in a solvent. The more abundant the solute is in solvent‚ the higher the rate of osmosis through the diffusion gradient forming a hypertonic or hypotonic solution. Solvent with equal or no solute forms an isotonic solution. Throughout this lab‚ data was collected and compiled to analyze these effects across selectively

    Introduction: Photosynthesis is the process by which green plants use the light energy to convert carbon dioxide and water into simple sugar called glucose‚ which provides a basic energy source for the plant. Photosynthesis occurs in leaves that contain specialized cell structures called chloroplasts. Chloroplasts contain molecules of a green pigment called chlorophyll‚ consisting largely of carbon and hydrogen. It gives green color and absorbs the necessary light for photosynthesis. Chloroplasts

    rate of photosynthesis using leaf discs. Aim : To measure the effect of light intensity on the rate of photosynthesis in leaf discs. Introduction : The simple concept of photosynthesis is that it can occurs in the presence of light‚ which takes place in the chloroplasts of green plant cells. Photosynthesis can also be defined as the production of simple sugars from carbon dioxide and water causing the release of glucose and oxygen. The chemical equation for photosynthesis can be expressed

    Photosynthesis is the process of transforming light energy into chemical energy that is used to build carbohydrates. Light reactions occur in the thylakoid membrane of the chloroplast‚ sunlight and water are the substrates for this reaction. The conversion of light energy can go through two pathways: noncyclic and cyclic. In noncyclic light transport‚ both Photosystems II and I are involved producing ATP and NADPH. Photosystem II absorbs 680 nm of light energy‚ with the oxidation of water; chlorophyll
