Photosynthesis test

• What does it mean when it is stated "that means it did not work"?

  It indicates that the experiment or process was unsuccessful.
• What caused the normal leaf to grow?

  Smoke
• What is the role of chlorophyll in plants?

  To collect energy for photosynthesis
• What are the variables in the plant growth experiment described?

  • Independent Variable (IV): Different types of plants
  • Dependent Variable (DV): Growth of the plant (height)
  • Controlled Variable (CV): Same conditions (amount of water)
• How do you calculate the height of the plant in the experiment?

  By measuring the start and end heights and then subtracting them.
• What is the formula to calculate the height of the plant?

  Height = End height - Start height
• If the start height of a plant is $10 \text{ cm}$ and the end height is $15 \text{ cm}$, what is the height growth?


  $Height =$$15 \text{ cm} - 10 \text{ cm} =$$5 \text{ cm}$
