2.9 Photosynthesis

4. A limiting factor for photosynthesis as it influence how much kinetic energy the reactants have and how many successful collisions take place per second.
6. main photosynthetic pigment of green plants.
8. 2 words. An environmental factor, such as carbon dioxide or light intensity, that controls the process of photosynthesis.
9. the production of carbon compounds in cells using light energy.
10. 3 words. The rate of conversion of carbon dioxide and water to photosynthetic products.
14. Light has different......... only red and blue are absorbed strongly causing high activity for the process of photosynthesis.
15. 2 words. Range of wavelengths of light within which photosynthesis takes place.
16. Pigments other than chlorophyll that take part in photosynthesis by helping to provide excited electrons.

1. one billionth (10-9) of a metre.
2. the distance between peaks of a wave of light, which determines its colour.
3. cell organelle that is the site of photosynthesis.
5. a method of separating and identifying the components of a complex mixture by differential movement through a two-phase system.
7. 2 words. Range of wavelengths of light that a pigment is able to absorb.
11. Two words. A limiting factor for photosynthesis as it influence how much substrate there is for the carbon fixation step.
12. A limiting factor for photosynthesis as it is one of the substrates and required to stop wilting of leaves and cells becoming flaccid.
13. chemical decomposition of water induced by light.
