Fill the 4 steps of photosynthesis in the following figure:
Sunlight will be
absorbed by
chlorophyll
Energy will be released
ATP will be used to
bind CO2 with more
hydrogen
Glucose will form

2. Critical thinking question:
From your understanding to photosynthesis steps and reactions, discuss in pairs and write 2 main
importance of photosynthesis to life on Earth and to Humans.
____we cant live without plants because it gives us oxygen,food,and it helps in many other things like
animals will not survive long enough because they will fight each other for
