Respiration involves breaking of . . . . . . bonds of complex compounds through oxidation within the cells,leading to release of considerable amount of energy.

Which of the following reasons explain why plants do not have specialized respiratory organs?
$I-$ Each plant part takes care of its own gas exchange needs.
$II-$ There is very little transport of gases from one plant part to another.
$III-$ The rate of respiration in plants is much slower compared to animals.
$IV-$ Plants have a higher requirement for gas exchange.
$V-$ During photosynthesis,the plant's requirement for oxygen from the atmosphere increases.
$VI-$ In large,dense plants,gases can diffuse over long distances.
$VII-$ In plants,each living cell is located very close to the plant surface.
