Introduction
Passive diffusion is the transport process in plants by which plants can transport nutrients across the membrane to its various parts.
Pre-Requisites:
• Plant nutrients, concentration gradient. • Structure of plants.
Activity:
See different plants and see whether as plants become old does it affects their transport mechanism?
Real Life Question:
When we soak a sponge in water, how fast it absorbs all the water. Similarly plants absorb and transport all its nutrients.
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Passive diffusion | Movement of molecules from higher concentration to lower concentration. |
| Energy requirements | No energy is required. |
| Rate of diffusion | Affected by concentration gradient, permeability of the membrane, temperature and pressure. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Water a plant in a garden | See how fast the water is absorbed by the soil and the plant. |
Real life uses :
When we water a plant, how the water reaches all the parts of the plant.
Places to visit :
Garden or a farm

What you learn in Theory:
Passive diffusion in plants.
What you learn in Practice:
How does passive diffusion help all the parts of the plants to get its nutrients and grow.
