Stoma
Where does photosynthesis specially occur
In the chloroplast

___ are plant pigments too. (these look yellow,orange, and Red). As chlorophyll dies in the fall, the green color fades and is replaced by ___
Cartencids
Chlorophyll absorbs mostly
Red and blue wavelengths of light
-occurs in thylakoids/grana
-sun’s energy is absorbed and changed into chemical energy in ATP AND NADPH-
Light-dependent reaction
