Respiration Photosynthesis
1. Respiration is a catabolic process in which compounds are broken down.
2. In this process the carbohydrates are broken down into simple sugars.
3. The end of the products is CO2 and H2O.
4. Occur during day and night. Light is not necessary for this process.
5. Energy is released from food material.
1. Photosynthesis is an anabolic process in which compounds are formed.
2. In this process the carbohydrates are manufactured.
3. The end product of this process is simple carbohydrates.
4. Occur during day time only. Light is necessary for the process.
5. It is energy coming process.
Renewable Resources of Energy Non-Renewable Resources of Energy
1. Renewable resources are used continuously and can be used again and again.
2. Examples are air, water, soil, wild life, forests, fish etc.
3. Renewable resources are constantly renewed by biogeochemical cycles of nature. E.g.: Animals take O2 and return to CO2 to environment.
1. Non-renewable resources of energy cannot be used again and again after their consumption.
2. Major examples include coal, oil, natural gas etc.
3. Non-renewable resources are being exhausted a day by day because their demand rise. Due to worldwide demand of fossil fuels; its supplies are declining.
Artery Vein
1. Arteries are blood vessels which transport blood away from the heart.
2. The inside lumen or bore of the arteries is narrow.
3. Arteries carry oxygenated blood with the exception of pulmonary artery.
4. The walls of the arteries are elastic.
5. The blood is under great pressure in arteries
Arteries are end in capillaries.
1. Veins are blood vessels which always carries blood towards the heart.
2. The inside bore or lumen of veins is wide.
3. The walls of vein are less elastic.
4. The blood under less pressure in veins.
5. Veins start from capillaries.
Lymph Plasma
1. Lymph is the part of blood which comes out of the blood capillaries.
2. The lymph is in direct contact with tissues.
3. The lymph usually contains Bacteria.
4. Lymph moves slowly. 1. Plasma is that part of blood which remains inside the blood vessel.
2. The plasma doesn’t have a direct contact with the tissue.
3. Plasma usually does not contain Bacteria
4. Plasma move quickly.
Laser Light Ordinary Light
1. Laser light is disciplined light.
2. Laser light has photons of same length.
3. It can be focused on very small point.
4. It is coherent light.
5. It is used in medicine and for diagnostic purposes.
1. It is undisciplined light.
2. Ordinary light has no photons of the same length.
3. It cannot be focused on a very small point.
4. It is incoherent light.
5. It has no medical use.
