Spiracles are the tiny pores present in the insects like cockroaches which help in gaseous exchange whereas stomata are the openings present on the surface of the leaves. They also help in gaseous exchange. The differences between the two structures are as follows:
•Spiracles are present laterally i.e. on the sides of the body of the organism whereas the stomata are present on the surface of the leaves.
•Spiracles are less in number as compared to that of the stomata.
