Gas Exchange and Photosynthesis

• gases


  are important because they are required for different metabolic reactions to proceed
• gas exchange


  involves the use of oxygen produced by photosynthetic organisms and the release of carbon dioxide to the environment as a waste product of respiration
• gas exchange in animals


  involves a system of parts and processes. It starts with the diffusion of oxygen from the respiratory surface into the blood, which transport the oxygen to the cells of the different parts of the body
• cell membrane


  is used by unicellular organisms for gas exchange. Gases directly pass through the ____ ________ through diffusion
• Chemoautotrophic organisms


  use chemicals to create a simpler organic substance important for them survival.
• gills


  is a respiratory surface covered with thin and moist epithelial cells that allow oxygen and carbon dioxide exchange
• frogs


  The____ uses its skin for gas exchange. This is why the skin of a ____ has to kept moist at all times
• photosynthesis


  it is the process of food production that happens in plants or autotrophs
• autotrophs


  organisms that can produce their own food
• leaves


  It is the main organ of Photosynthesis in plants
• stomata


  Tiny openings or pores in plant tissue that allow for gas exchange
• • chloroplast

  • It contains the green pigments called chlorophyll which gives the plant its distinct color
  • Organelle where Photosynthesis takes place
• stroma


  Refers to the colorless fluid surrounding the granum within the chloroplast
• granum


  Series of flattened interconnected sacs that looks like a pancake
• thylakoid


  any of the membranous disks of lamellae within plant chloroplasts that are composed of protein and lipid and are the sites of the photochemical reactions of photosynthesis.
• Light dependent reaction and Light independent reaction 


  two stages of photosynthesis
• light dependent reaction


  it is the stage where the chlorophyll absorbs the energy from the sun
• light independent reaction


  also called as dark reaction named after Dr. Melvin Calvin also known as Calvin Cycle ( occurs in Stroma)
