Key Terms:
chloroplast- organelle found in some plant ceels and certain unicellular organisms where photosynthesis takes place
chlorophyll- pigment that gives a chloroplast its green color; uses light energy to split water molecules during photosynthesis
stroma- thick fluid contained in the inner membrane of a chloroplast
thylakoid- disk-shaped sac in the stroma of a chloroplast; site of the light reactions of photosynthesis
light reaction- chemical reactions that convert the sun's energy to chemical energy; take place in the membranes of thylakoids in the chloroplast
Calvin cycle- cycle in plants that makes sugar from carbon dioxide, H+ ions, and high-energy electrons carried by NADPH
Summary:
Chloroplast:
* photosynthesis takes place in chloroplast
* contain chemical compound called chlorophylls which make these in to green color.
* leaves contain most of the chloroplast in entire plant
* has an inner and outer membrane just like mitochondrion
* in the stoma, there have a lot of thylakoids which are all enclosed by a membrane
Photosynthesis:
* formula - 6CO2 + 6H2O →→→ C6H12O6 + 6O2
- 6 Carbon Dioxide + 6 Water →→→ Glucose + Oxygen
* During this process, choroloplast must require to have light energy and have light reactions so this process will be working
* light reaction comes from the light of the sun
* Calvin cycle makes sugars from the atoms in carbon dioxide plus the hydrogen ions and the high-energy electrons carried by NADPH.
1. Draw and label a simple diagram of a chloroplast that includes the following structures: outer and inner membranes, stroma, thylakoids.
2. What are the reactants for photosynthesis? What are the products?
Reactants: 6sCarbon Dioxide and 6 Water
Products: Glucose and 6 Oxygen
3. Name the two main stages of photosynthesis. How are the two stages related?
Two main stages are the light reaction and the Calvin cycle. These two stages are related by the molecules they use which are NADPH and some ATP to produce molecules that they need.
