Plants and photosynthesis

• What is the equation for photosynthesis

  Carbon dioxide + water + light energy -> glucose + oxygen
• How does the photosynthesis rate affect plant growth?

  A higher rate produces more energy for growth
• What is the relationship between photosynthesis rate and plant strength?

  A higher rate allows plants to grow stronger
• What is the definition of photosynthesis rate?

  Speed at which plants convert sunlight into energy
• What are the key trends in atmospheric carbon dioxide levels since the 1700s?

  1. Stable levels until Industrial Revolution
  2. Rapid increase from 1900s
  3. Sharpest rise since 1960s
  4. Current level at highest point in human history
• What significant change occurred in atmospheric carbon dioxide levels since the 1960s?

  Sharpest rise in levels
• When did atmospheric carbon dioxide levels start increasing dramatically?

  Since the 1700s
• If a plant has a high photosynthesis rate, what can be inferred about its energy production?

  It produces more energy for growth
• When did the rapid increase in atmospheric carbon dioxide levels begin?

  From the 1900s
