Differentiate between the following: (1)Respiration in plants and animals. (2)Aerobic and anaerobic respiration (3)Inhalation and Exhalation

Respiration in plants and animals:

 

Respiration in plants is a passive process, which means the breathing occurs on a cellular level, not by active muscular movements. Respiration in animals is an active process of inhaling oxygen and exhaling carbon dioxide using muscular movements and energy.

 

Plants do not possess a well-developed respiratory system like most animals. Plants mainly breathe through pores in their leaves called stomata.

 

Plants take in carbon dioxide and give out oxygen, whereas animals take in oxygen and give out carbon dioxide.

 

Unlike plants, most animals use a circulatory system to transport respiratory gases to different parts of the body.

 

 

 

Inhalation	Exhalation
Inhalation is a process where you take in air i.e. oxygen from the external environment, through the air ways, and into the alveoli.	Exhalation is breathing out of carbon dioxide out of the bronchial tubes, through the airways, to the external environment
It is an active process	It is a passive process
Caused by muscular contraction mainly of the diaphragm and intercostal muscles	Mainly caused by elastic recoil of the diaphragm and relaxation of the intercostal muscles

 

 

 

Aerobic and anaerobic respiration:

Aerobic Respiration	Anaerobic Respiration
Here oxygen is used	Here oxygen is not needed
It occurs in cytoplasm and mitochondria	It occurs in cytoplasm only
38 mol ATP is produced per mol glucose	2 mol ATP is produced per mol glucose
Its stages are glycolysis, pyruvate oxidation, Krebs cycle	Only glycolysis occurs here.
