State some points which highlights the importance of diffusion in plants.
Answers
Answer:
Diffusion is a very important process for photosynthesis where carbon dioxide from the stomata diffuses into the leaves and finally into the cells.
during transpiration, the water and oxygen diffuse from the leaves into the environment.
It includes the movement of particles of a medium from the region of its higher concentration to the region of its lower concentration without the expenditure of energy.
This process is slow and occurs mostly in gases and liquids.
The rate of diffusion is affected by various factors like temperature and pressure, concentration gradient, separating membrane’s permeability etc.
Answer:
The following points highlight the importance of diffusion in plants :
▪ Exchange of gases through stomata takes place through the process of diffusion.
▪ Loss of water vapour from the aerial parts of the plant,i.e., transpiration involves the process of diffusion.
▪ Diffusion is involved in translocation of food in plants.
▪ Diffusion of aromatic compounds from the flowers helps in attracting the pollinating agents.
