  • enters through the roots
  • travels up the stem
  • enters the leaves

2) How does CO2 enter the leaf?

  • It comes in as a gas through the stomata in the leaves.
  • Most of the stomata are on the underneath of the leaves.

5) What is a waste product for the plant and how it is removed from the plant?

  • The major waste product for the plant is oxygen which is released back into the

7) What are the final products of photosynthesis and how are they important to life on this planet?

  • The final products of photosynthesis are glucose (sugar) and oxygen.
  • The oxygen allows animals and other organisms to breathe and produce energy through cellular respiration.
  • The sugar (food) is also used by other organisms to make energy.
  • Both oxygen and glucose are ingredients in the process of cellular respiration, which all organisms undergo, to make energy.
