Further Investigations: Where are photosynthetic autotrophs found in your life?

  1. Create a field notebook identifying photosynthetic autotrophs around your home. Investigate the different groups and prepare a report comparing and contrasting their biology.
  2. Look through the ingredients list on food items in your house. Are there any food items with ingredients that come from algae? (Hint: look for carrageenan from red algae, alginate from brown algae, and beta-carotene from green algae.) Present your findings to your class.
