Question

sometimes higher plants and animals too perform anaerobic respiration give scientific reason

Answer 1

Due to absence of oxygen sometimes plants and animals perform anaerobic respiration .Ex - tape worm in the stomach

Answer 2

Higher plants and animals too perform anaerobic respiration:

• During intense working and activity sometimes there is a lack of oxygen takes place in the muscles of some higher group of multicellular organisms.
• During this stage when there is a lack of oxygen but the body needs energy the cells of the body starts doing the anaerobic respiration.
• It is the respiration without oxygen to prepare the extra amount of energy required due to which certain amount of lactic acid is produced as a byproduct.  
• The presence of this acid in the body between the muscles can cause a lot of pain.  
• The intensity of pain depends on the intensity of activity that has been done and the amount of respiration that has produced lactic acid.
