Photo synthesis

• What is the process of photosynthesis primarily producing?

  Glucose
• Where does photosynthesis take place in plants?

  In the chloroplasts
• What is the chemical equation for photosynthesis?

  carbon dioxide + water → oxygen + glucose
• What role does chlorophyll play in photosynthesis?

  It absorbs light
• What do tiny holes in leaves allow for?

  Gas exchange
• How is glucose transported in plants?

  To all parts of the plant
• From where is water transported in plants?

  From the roots to the stem and leaves
• What is the function of the waxy layer on leaves?

  Reduce water loss by evaporation
• Where are chloroplasts mainly located in leaves?

  On the upper side of the leaf
• How do plants take in carbon dioxide?

  Through tiny holes
• What minerals do plants need for healthy growth?

  1. Nitrates for growth
  2. Phosphates for healthy roots
  3. Potassium for healthy leaves and flowers
  4. Magnesium for making chlorophyll
• What happens if a plant lacks a mineral?

  It may suffer from a mineral deficiency
• How can farmers address mineral deficiencies in soil?

  By using fertilizers
• Where are stomata located in leaves?

  On the lower surface
• What is the role of guard cells in leaves?

  Regulate the opening and closing of stomata
• What adaptations do leaves have for photosynthesis?

  • Lots of green chlorophyll
  • Thin structure for gas diffusion
  • Large surface area for light absorption
  • Veins for transporting water and glucose
• What is the equation for aerobic respiration?

  glucose + oxygen → carbon dioxide + water (+ energy)
• Where does respiration occur in cells?

  In the mitochondria
• How is glucose absorbed into the bloodstream?

  From the small intestine
• How is oxygen transported to cells?

  By hemoglobin in the blood
• What happens to carbon dioxide produced in cells?

  It diffuses into the blood plasma
• Where is carbon dioxide transported after leaving the cells?

  To the lungs
• What is the equation for anaerobic respiration in animals?

  glucose → lactic acid (+ energy)
• When does anaerobic respiration occur?

  When there is not enough oxygen
• What is a consequence of lactic acid production?

  It can cause muscle cramps
• What is the term for the oxygen needed to break down lactic acid?

  Oxygen debt
• What is the equation for fermentation in microorganisms?

  glucose → ethanol + carbon dioxide (+ energy)
• What are the main products of fermentation in yeast?

  • Ethanol
  • Carbon dioxide
  • Energy
• What is the significance of fermentation in yeast?

  It is important in food production
