Introduction
Description of the photosynthesis mechanism of C3 plants.
- 3 Carbon compund
- Stoma are open during the day
- Photosynthesis take place in the leave
- RUBISCO, the enzyme involved in photosynthesis, is also the enzyme involved in the uptake of CO2.
- Most plants are C3
Description Of the photosynthesis mechanism of C4 plants.
- CO2 is first incorporated into a 4-carbon compound
- Stoma are open during the day
- Uses PEP Carboxylase for the enzyme involved in the uptake of CO2. This enzyme allows CO2 to be taken in by the plant. Then CO2 is directed to RUBISCO for photsynthesis.
Task
Process
10 species of plants that undergo C3 photosynthesis.
- Wheat
- Oranges
- Grapes
- Coffee plant
- Peanut
- Lemon
- Potatoes
- Carrots
- Peaches
- Apples
10 species of plants that undergo C4 photosynthesis.
- Crab Grass
- Corn
- Amaranth
- Sorgham
- Millet
- Sugarcane
- Nut grass
- Crab Grass
- Barnyard grass
- fourwinged salt bush
Evaluation
The environmental conditions in which the 4 species of C3 plants are found.
Peaches are grown in the USA.
Peanuts are found Asia, Africa, Australia, and North and South America.
Grapes are found Mediterranean region, France, Germany, England and USA.
Potatoes are grown in Russia, Europe, France, Germany, Poland, UK, USA and Canada.
The environmental conditions in which the 4 species of C4 plants are found.
Corn is found in central Europe and north America.
Crab grass grows everywhere.
Sugarcane growns in tropical South and Southeast Asia.
Millet is grown in Asia, Russia, mainland China, India and western Europe and United States.
Conclusion
A comparison (similarities and differences) between the 2 types of photosynthetic mechanisms.
Both systems are efficient dependingon the regoin in which it is used.
C3 is more commen in places and C4 has one more carbon.
