Question
List the factors on which diffusion in the plants depends.
✓
Answer
Diffusion is a phenomenon explaining movement of substances from its higher concentration to its lower concentration. In plants, diffusion of gases occurs. Factors affecting diffusion are:
Factors on which the diffusion depends are:
Factors on which the diffusion depends are:
- TEMPERATURE: With the rise in temperature, the rate of diffusion increases. Because with the rise in temperature, the kinetic energy of diffusing particles also increases.
- DIFFUSION PRESSURE GRADIEN: Greater the diffusion pressure gradient , more will be net diffusion of molecule.
- DENSITY OF DIFFUSING SUBSTANCE: The rate of diffusion is inversely proportional to square of the density of the diffusing substance.
- MEDIUM: More the concentrated medium, slower will be rate of diffusion.

If the teeth are not cleaned regularly, they become covered with a sticky yellowish layer W of food particles and bacteria. Since layer W covers the teeth, the alkaline liquid X secreted by glands Y inside the mouth cannot reach the teeth surface to neutralise the acid formed by the action of organisms Z on sugary food, and hence tooth decay sets in.
- What is W known as?
- What is (i) X, and (ii) Y?
- What are organisms Z?
- State one way of removing layer W from the teeth.
