Case Study Questions on Respiration in Organisms
Questions
Question 1:
Read the given passage below and answer the question:
Respiration occurs in all organisms including animals. Plants, fungi and bacteria, Respiration involves exchange of gases. However, the mode of external respiration varies from organism to organism, but the basic process of respiration is similar in all living organisms. Breathing involves two processes. During breathing, we breathe in air which is transported to all parts of the body and ultimately to each cell. Some organisms that can survive in the absence of air, they can respire too.
Q. 1. An animal can respire both from lungs and skin.
(a) earthworm
(b) yeast
(c) fish
(d) frog
Difficulty Level: Medium
Ans. Option (d) is correct Explanation: Though frogs have a pair of lungs, they can also breathe through their skin.
Q. 2. Which part of a plant is involved in the gaseous exchange?
(a) leaves
(b) roots
(c) stems
(d) All of these
Difficulty Level: Easy
Ans. Option (d) is correct.
Explanation: The entire plant is involved in gaseous exchange leaves (stomata), stem (lenticels) and general surface of the roots.
Q. 3. Choose the group given below on which breathes through gills:
(a) cow, goat and crocodile
(b) cockroach, grasshopper and ant
(c) fish, prawn and tadpole
(d) crow, whale and snake
Difficulty Level: Medium
Ans. Option (c) is correct.
Explanation: The gills are the respiratory organs in fish, prawn and tadpole. Gills are the aquatic organisms in breathing underwater.
Q. 4. What is cellular respiration? Explain the two types of cellular respiration.
Difficulty Level: Medium
Ans. The process of breakdown of food in the cell with the release of energy is called cellular respiration. There are two types of cellular respiration are:
Aerobic respiration: It occurs in the presence of oxygen.
Anaerobic respiration: It occurs in the absence of oxygen.
Q. 5. How breathing and respiration are different?
Difficulty Level: Difficult
Ans. Breathing and respiration are different because breathing is only the mechanical process of exchange of gases whereas respiration involves both the mechanical and the biochemical processes.
