Answer: endothermic
Explanation: An endothermic reaction is a type of of chemical reaction in which energy is absorbed from the surrounding. The temperature of the surrounding decreases.
An Exothermic reaction is a type of chemical reaction in which energy is released into the surrounding. The temperature of the surrounding increases.
[tex]6CO_2+6H_2O\rightarrow C_6H_{12}O_6+6O_2[/tex]
Thus as photosynthesis is taking place, it absorbs energy from surroundings in the form of sunlight and thus is considered as endothermic reaction.
