In photosynthesis is carbon dioxide reduced to glucose while water is oxidized to oxygen? am I correct? If not, can someone explain what's reduced into what and what's oxidized into what?

Google "photosynthesis."
yes you are correct.
the equation for photosynthesis:
6 CO(2) + 6 H(2)O + energy --> C(6)H(12)O(6) + 6 O(2)
^
the above equation basically says Carbon Dioxide + Water + energy ---yields---> glucose + oxygen
the carbon dioxide gets reduced to glucose (gain H+ atoms) while water gets oxidized into oxygen (loses H+ atoms).
key terms: reduce (gaining of H+ atoms); oxidize (losing of H+ atoms)
also, the opposite of photosynthesis is cellular respiration. The equation for cellular respiration is just the opposite of what I have above, but starting from the right moving to the left, switch the arrow to the opposite direction, and whatever that was oxidized is now reduced and whatever that was reduced is now oxidized.
