Leaves of a healthy potted plant were coated with Vaseline to block the stomata. Will this plant remain healthy for long? State three reasons for your answer.

OR

i. Why do fishes die when taken out of water?

ii. Why is the rate of breathing in aquatic organisms much faster than in terrestrial organisms?

Answer :

This plant will not live for long with leaves coated with Vaseline to block stomata because:


√ No photosynthesis takes place as no sunlight is received by the plant.


√ No transpiration as water is not able to evaporate or ooze out of stomata.


√ No respiration as no intake of carbon dioxide takes place.


OR


i. Fish respire with a specialized organ called gills. Gills are richly supplied with blood capillaries and readily absorb oxygen from water. When fish is taken out of the water, the walls of gills collapse. As a result, it is not able to take oxygen from air and hence, die due to oxygen deficiency.


ii. Aquatic organisms are those who live in water and breathe using oxygen dissolved in water. Terrestrial organisms are those who live on land and breathe oxygen directly from the atmosphere. As the amount of oxygen is less in water as compared to land, this is the reason why aquatic animal breathe faster than a terrestrial animal so that it can acquire more amount of oxygen.
