Final answer:
The openings of tracheal tubes in insects are called spiracles, not ooerculum.
Step-by-step explanation:
No, the statement is false. The openings of tracheal tubes in insects are not called ooerculum. They are called spiracles. Insects have spiracles along their thorax and abdomen, which allow air to enter into the tracheal system. These spiracles connect to a network of tubules that carry oxygen directly to the tissues throughout the body. The tracheal system is a highly specialized respiratory system in insects.
The statement that the openings of tracheal tubes in the insects are called operculum is false. Insects have structures known as spiracles, which are the openings through which air enters into the tracheal system, allowing oxygen to be transported directly to the tissues. The tracheal system in insects consists of a series of small tubes made of chitin that conducts air from the spiracles to the tissues, playing a crucial role in their respiratory process.
