What is the adaption of the orgaisms with the surrounding envirmoent to get their required air ?
Answers
Respiration in Plants:
1. Plants exchange gases through Stomata.
2. Plants have large inter cellular spaces that ensures that all cells are in contact with air.
3. Carbon-di-oxide and Oxygen are exchanged through Diffusion.
Rate of Diffusion depends upon Environmental conditions and Requirements of the plant.
4. During Day time, Carbon-di-oxide is taken up by the atmosphere and oxygen is released through the process of Photosynthesis.
5. At Night, Oxygen is taken-in and carbon-di-oxide is given out just like other living beings.
Respiration in Terrestrial Animals:
1. Land Animals have evolved Specific organs for intake of Oxygen from the Atmosphere and elimination of carbon-di-oxide.
2. Their Respiratory organs have large surface area to increase contact with oxygen rich air.
3. They have extremely fine and delicate surface for efficient diffusion of gases.
4. Such organs are placed within the body and protected by Rib-cage.
5. There are passages that take Air in and out of these organs.
Respiration in Aquatic Animals:
1. Aquatic Animals have to absorb oxygen that is dissolved in water.
2. Amount of oxygen dissolved in water is always less that the amount of oxygen dissolved in air.
3. So, Breathing rate of Aquatic animals is always greater than Breathing rate of Terrestrial animals.
4. Fishes take-in water through their mouths and force it through their gills.
Gills absorb dissolved oxygen from water and lets it to the blood.
