Photosynthesis reaction and equation
Producers make their own food, They convert materials found in their environment into glucose, a carbohydrate, by using sunlight.
Carbon Dioxide + Water →light energy Glucose+Oxygen
The reactants are Co2 and water. The carbon dioxide diffuses into the plnt through the Stomata. The water diffuses into the plant throught the root hair cells. The reaction happens in the chloroplast inside the plant cells.
Limiting factors for photosynthesis
Three factors can limit the speed of photosynthesis: light intensity, carbon dioxide concentration and temperature.
- Light intensity. Without enough light, a plant cannot photosynthesise very quickly, even if there is plenty of water and carbon dioxide. ...
- Carbon dioxide concentration. ...
Adaptations of a leaf
Large surface area To absorb more light
Short distance for carbon dioxide to diffuse into leaf cells
Absorbs sunlight to transfer energy into chemicals
Network of veins
To support the leaf and transport water and carbohydrates
Allow carbon dioxide to diffuse into the leaf
Word equations for Earobic and Anarobic respiratio
Glucose + Oxygen → Carbon Dioxide + Water (energy)
- Happens in the Mitochondria
Glucose → Energy + Lactic Acid
- Happens in the cytoplasm
Differences between Aerobic and Anarobic respirati
Unlike aerobic respiration, anaerobic respiration does not need oxygen. It is the release of a relatively small amount of energy in cells by the breakdown of food substances in the absence of oxygen.
AerobicAnaerobic Oxygen Needed Not needed Glucose breakdown Complete Incomplete End product(s) Carbon dioxide and water Animal cells: lactic acid. Plant cells and yeast: carbon dioxide and ethanol Energy released Relatively large amount Relatively small amount
