oxygen.
Steps in Respiration
Aerobic Respiration
1. Fatigue
3. Glucose breaks down into carbon 3. Glucose breaks down into ethyl
dioxide and water. alcohol, carbon dioxide and
energy.
1. Plants
2. Simple Animals
3. Human Beings
2. IRespiration :
Through Diffusion.
The root hair are in contact with the air in the soil-
Oxygen diffuses into root hairs and reaches all other
cells of the root for respiration. CO2 gas produces in the
cells of the root during respiration moves out through
the same root hairs by the process of diffusion.
Respiration in Stems:
Fishes : Gills
● Nose
● Nasal passage
● Trachea (windpipe)
● Bronchi
● Lungs and
● Diaphragm.

● The trachea runs down the neck and divides into two
