How does respiration in plants differ from animals
Answers
Answer:
In plants all parts like root, stem, leaves, etc ..,perform respiration individually, while in animals either the general body surface organs like skin, gills, lungs, etc.., are involved in the respiration
The rate of respiration is much slower in plants than in animals. Unlike animals there is little transport of gases from one part of the plant to another
RESPIRATION IN PLANTS:-
- plants only respire
- Plant obtain oxygen directly from the air through stomata.
- Carbon dioxide released during respiration is utilized by plants for photosynthesis.
a) Respiration in roots: Oxygen present in the airspace of the soil get diffused into the root hairs.
b)Respiration in stems: In higher plants, stem possesses small opening called as lenticles through which oxygen get diffused. In the case of plants with green stems, they possess stomata through which oxygen get diffused.
c)Respiration in leaves: Leaves possess small opening called as stomata through which exchange of gases takes place. The opening and closing of stomata help in the exchange of gases between leaves and atmosphere and it is controlled by the guard cells.
Respiration in animals:-
- Animals breath air for cellular respiration.
- Animals inhale oxygen from nose or gills into respiratory organs.
- Carbon dioxide released during respiration is not utilized by animals
