4.1 Ear anatomy. The ear can be seen as three parts: the outer ear, the middle ear and the inner ear - each with a dedicated function. The outer ear consists of the ear shell (pinna) and the auditory canal. Its function is to guide air pressure waves to the middle ear- with the ear shell increasing the sensitivity of the ear to the front side of the head, supporting front/rear localisation of audio signals.
Photosynthesis occurs in two stages. In the first stage, light-dependent reactions or light reactions capture the energy of light and use it to make the energy-storage molecules ATP and NADPH. During the second stage, the light-independent reactions use these products to capture and reduce carbon dioxide.
7th Grade Life Science . Photosynthesis & Cellular Respiration Study Guide . 1. What is the overall reaction (formula) for photosynthesis? 6CO. 2 + 6H. 2. O + sunlight C. 6. H. 12. O. 6 + 6O. 2. Carbon Dioxide and Water and sunlight yield Glucose and Oxygen . 2. How does this compare to the overall reaction for cellular respiration? Photosynthesis and Cellular Respiration are the reverse reactions of each other. 3. Where does the energy for photosynthesis come from? The sun . 4. What plant pigment is involved in photosynthesis? Chlorophyll . 5. How does your body get the energy it needs from the food you eat (what process allows cellular energy to be made)? Cellular Respiration . 6. In what organelle of a plant cell does photosynthesis take place? Chloroplast . 7. What are the products of photosynthesis? Glucose and Oxygen . 8. Write the equation for photosynthesis (CO2WS GO). Make sure you memorize it. 6CO2 + 6H2O + sunlight C6H12O6 + 6O2. 9. What is the overall reaction (formula) for cell respiration?
