Insects and leaves of a plant have pores through which they exchange gases with the atmosphere. Can you write two points of differences between these pores with respect to their position, number and extension into the body?
उत्तर
Spiracles in insects and stomata on the leaves of a plant are pores through which gaseous exchange takes place. Differences between spiracles and stomata on the basis of their position, number and extension into the body are as follows:
- Spiracles are present on the sides of insects’ body while stomata are present on the lower surface of leaves.
