- 1B1.4 RespirationEquations
- 2The two main stages -light energy splits water into Oxygen has and hydrogen ions -carbon dioxide combines with hydrogen to create glucoseLight is absorbed by pigment called chlorophyll.
This is in the chloroplasts where photosynthesis happens
CO2 enters through the stomata
Water enters throug the roots and come through the Xylem. - 3Wash products -oxygen is formed -some is used for the plants respiration -the rest is released and used for animals and some microorganisms.Ways to measure photosynthesis
-amount of oxygen produced
-carbon dioxide uptake
-carbohydrate production - 4Factors effecting photosynthesis- light intensity Without enough light, a plant cannot photosynthesize very quickly. -increased light-increased rate of photosynthesis.
- 5Limiting factors- carbon dioxide -it is one of the reactants (along with water) -increasing the concentration will increase the rate until there is another limiting factor.Again, at some point, a factor may become limiting.
- 6Limiting factors- temperature -the reaction that combines water and carbon dioxide is controlled by enzymes. -at low temperatures, the rate of photosynthesis is limited by collisions. High temperatures cause the enzyme to denature.
