Respiration in Organisms - Chapter Wise CBSE Solved Question and Answer Based On NCERT
Long Q&A:
Q1: Explain the two types of respiration.
View Answer
Ans:
Aerobic respiration
Anaerobic respiration
An aerobic respiration takes place using oxygen, inhaled in breathing.
In aerobic respiration , breakdown of glucose results in production of Carbon Dioxide, Water and Energy
An aerobic respiration uses respiratory organs such as lungs or gills
Whereas an anaerobic respiration requires no oxygen.
In anaerobic respiration, the breakdown of glucose first results in Lactic Acid and energy then lactic acid break down into carbon dioxide and water.
anaerobic respiration take place at cellular or muscular level
Both aerobic and anaerobic respiration are necessary for the survival of living organism.
In both type of respiration, the food is broken and energy is released for the functioning of an organism.
In both type of respiration, Carbon Dioxide, Water and Energy is produced finally
Q2: Explain the process of breathing in insects and fishes.

Ans:
A cockroach has a small opening on the side of its body, these openings are called spiracles. Oxygen rich air rushes through spiracles into the tracheal tubes diffuses into the body tissue and reaches every cell of body. In the same way carbon dioxide from the cells goes into the tracheal tube and moves out through spiracles.
Water animals have gills that help them to use oxygen dissolved in water. Gills are projections of the skin which are well supplied with blood vessels for exchange of gases.
