* Activity 3.32 : Reviewing Photosynthesis and endothermic reactions.
3.32.a Copy the following Photosynthesis definition from the whiteboard.
( 10 points ).
( 10 points ).
3.32.c Look at the following processes and at the back of the paper make
a table and organize them according to if they are exothermic or
endothermic processes. I remind you that exothermic processes
release or give off energy and endothermic ones absorb it.
