Question

give the main points of difference between respiration in plants and respiration in animals

Answer 1

1.Both plants and animals generally show aerobic respiration. 
2.Both utilize oxygen for the oxidation of food and production carbon dioxide, along with the release of energy. 
3.Animals generally have special respiratory organs but plants do not.Oxygen enters through the stomata and the lenticels. 
4.Animals will have some type of ventilation movements to facilitate the entry and exit of air (except animals which breathe through their body surface) but plants absorb air by diffusion through out their body surface. 
5. Since plants utilize the carbon dioxide they produce during respiration for the process of photosynthesis, it appears as if they do not breathe during the daytime.They breathe, but the CO2 is not evolved during the day, only at night. 
6. Since plants are rooted to a spot, their overall energy requirement is less, hence the rate of respiration is also less than that of animals

Answer 2

Answer:

Explanation:

Respiration in Plants :-

• All parts of plants such as root, steam , leaf, flower and bud take part in respiration.

• Rate of respiration is low.

• Breathing does not occur.

• Exchange of gases takes place through Stomata.

Respiration in Animals :-

• Animals respire through certain respiratory organs only.

• Respiration rate is high.

• Breathing takes place in animals.

• Exchange of gases takes place in lungs.
