Photosynthesis

• Objective
• Describe the role of light chlorophyll in the
  process of photosynthesis.
• Basic Equation
• 6CO2 6H2O C6H12O6 6O2
• Reactants Products
• Definition chemical process that provided
  glucose for energy to perform all other life
  processes.

Photosynthesis

• Takes place in leaves
• Palisade cells packed with chloroplasts that
  contain chlorophyll
• Guard cells control movement of gases into out
  of the leaves. Stomata are pores with guard
  cells on either side.

3
Photosynthesis

• Guard cells also control the amount of water in
  the leaf
• Lots of H2O light No H2O light
• Turgid- swollen Flaccid- limp
• Stomata open Stomata close

Light Pigments

• Plants gather the suns energy with light
  absorbing molecules called Pigments.
• Chlorophyll principle pigment in plants,
  absorbs red blue light, reflects green light, 2
  types a b
• Accessory pigments carotene xanthophyll
• Chromatography reveals the pigments present in
  different types of plants by separating them.
