Respiration
This is the process where by the complex food substance is Brocken down step by step in order to release energy
 The process is decided into two category
1.aerobic respiration
2.anaerobic respiration

Aerobic respiration
Is the type of respiration which occur in the cell of organism in the prencense of oxygen

Carbohydrates +oxygen to yield carbon dioxide + water + energy


Anaerobic respiration
 Is the type of respiration which occur In the cell of organism in absence of oxygen
   Means carbohydrates is Brocken to yield alcohol in plants and lactic acid in animal
Alcohol produced in plant is ethanol
    For simply logical decomposition of carbohydrates 

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

Kulingana na wanafunzi wengi kuona masomo ya sayansi no magumu, napenda kuwatia moyo kuendelea kupambana ili kufanikiwa kusoma kwa bidii masomo hayo, maana fulsa nyingi ambazo zinahitajika kwenye nchi zinazoendelea no kusoma masomo hayo, ikiwemo
Physics
Biology
Chemistry
Basic mathematics
Geography
Na blog yetu itahusu uhamasishaji juu ya elimu, na pia itaendesha mijadala ya somo la biology na chemistry, na mtaalam wetu Dr Joseph chula
