Science Misconceptions on Respiration

Misconception (1):
Breathing is the same as respiration.

Right concept: 
Breathing is the exchange of gases between the air and our bodies. On the other hand, respiration is the process by which oxygen is used to break down food to provide our body with energy.

Misconception (2):
Plants carry out respiration only at night.


Right concept: 
Plants carry out respiration all the time, even when they are photosynthesising.
