Today we are going to explain the concept of photosynthesis


Photosynthesis
Is the process where by green plants and some microorganism eg. Euglena manufacture its own food in the prencense of light from sun, carbon dioxide and chrolophil and water

Raw material for photosynthesis to occur
1.water
2.sunlight
3.chrolophill
4.carbon dioxide 

Where by 
                  Water is the source of electron
                   Carbon dioxide provide carbon atom for carbohydrates formation
                   Chrolophil contain RUBP which act as carbon dioxide acceptor
                    
Products of photosynthes
1.water
2.oxygen
3.carbohydrates

Factor affecting the rate of photosynthesis
1.prencense of water
2.prencense of carbon dioxide
3.prencense of sunlight
4.number of phloem 


Adaptation of leaf to support photosynthesis
1.prencense of stomata to allow gaseous exchange
2.prencense of guard cell to allow opening and closing of stomata
3.prencense of vascular system for transportation of manufactured food
4.prencense of mesophilly

Adaptation of chroloplast to its function
1.prencense of ribosomes (70s) for for protein synthesis
2.prencense of circural DNA for self replication
3.prencense of double membrane which separate processes which occur in the cell and within the chroloplast
4.stroma contain RUBP act as carbon dioxide acceptor
5.the inner membrane is permiable allow material to pass through

       NB: the term RUBP mean ribrose biphosphate

Importance of photosynthesis

1.elimination of carbon dioxide in the atmosphere

2.liberation of oxygen to atmosphere

3.source of food
