NOTES ON LIFE PROCESS CLAS 10 CBSE

Answer 1

Life process is based on process which we perform regulary.

Respiration
 Mechanism of respiration in human beings
Nasal cavity
↓
Pharynx(common passage for air and food)
↓
Larynx(voice box)
↓
Trachea (wind pipe)
↓
Bronchi
↓
Bronchioles
↓
Alveolar sacs (provide surface area for exchange of gases)
---
O₂ haemoglobin ⇒ Oxyhaemoglobin
CO₂ haemoglobin ⇒ Carbamino haemoglobin
CO haemoglobin ⇒ Carboxyhaemoglobin
---
Transportation
Transportation in plants
energy stored organ - Leaves
absorbtion organ - root

If the distance b/w root and leaves is short then simple diffusion is enough for tansprtation.
If the distance b/w root and leaves is large then it must have specialised tissue for tansprtation.
