Ideal conditions for photosynthesis

• What is one of the main challenges of growing plants outdoors on a large scale?


  It is almost impossible to control the weather and other conditions.
• How can ideal conditions for farming be artificially created?

  By growing plants in a greenhouse.
• What is the primary function of a greenhouse in farming?


  To trap the Sun’s heat and maintain an ideal temperature.
• What might a farmer use in winter to maintain the ideal temperature in a greenhouse?

  A heater.
• What measures might be taken in summer to prevent overheating in a greenhouse?

  Using shades and ventilation.
• Why is light essential for photosynthesis?


  Because it is needed for the process of photosynthesis.
• How do commercial farmers extend photosynthesis time for their plants?


  By supplying artificial light after sunset.
• What types of plants are commonly grown in greenhouses?


  Food crops, flowers, and tobacco plants.
• How can farmers increase the level of carbon dioxide in a greenhouse?


  By using a paraffin heater.
• What is a by-product of burning paraffin in a greenhouse?


  Carbon dioxide.
• What advantage does keeping plants enclosed in a greenhouse provide?


  It makes it easier to keep them free from pests and diseases.
• What can farmers add to the soil in a greenhouse to promote healthy growth?

  Fertilizers.
• What is the trade-off for farmers when creating ideal conditions for photosynthesis?


  It costs money to maintain these conditions.
• Why is it important for farmers to supply just the right amount of heat and light?


  To ensure plants grow well without wasting money.
• What are the key factors that farmers control in greenhouses to optimize photosynthesis?


  • Carbon dioxide levels
  • Light availability
  • Temperature control
  • Use of paraffin heaters, artificial light, and ventilation
• What does ensuring nothing becomes a limiting factor for photosynthesis lead to?


  A good crop being produced.
