Questions & Step-by-Step Solutions

Which structure in plants is primarily involved in gas exchange?
  • Step 1: Understand that plants need to take in gases from the air.
  • Step 2: Identify that the main gases involved are carbon dioxide (for photosynthesis) and oxygen (as a byproduct).
  • Step 3: Learn that plants have special structures on their leaves called stomata.
  • Step 4: Recognize that stomata are tiny openings that can open and close.
  • Step 5: Realize that when stomata open, gases can enter and exit the plant.
  • Step 6: Conclude that stomata are the primary structures in plants responsible for gas exchange.
