Some Experiments on Breathing and Respiration
Some Experiments on Breathing and Respiration: Overview
This topic describes the process of respiration in plants and animals. It discusses the organs used for respiration by humans, animals, fishes and insects with pictures. It also mentions how plants respire through holes in their leaves.
