Question

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?

Answer 1

Spiracles:

1. Some species of animals have openings on the skin's surface that lead to the airways known as Spiracles.
2. Insects may have it in the exoskeleton, which allows air to enter an area called the trachea.
3. They can be located laterally along the chest and are found in the abdomen of some insects.

Stomata:

1. The passage of gas into and out of the leaves, and consequently the entire plant, is controlled by stomata, tiny pores on the surface of the leaves, and stems.
2. They adjust to regional and global changes from minutes to thousands of years.

Spiracles	Stomata
Spiracles are the microscopic pores found on the epidermis of leaves and stems of plants	Stomata are the respiratory holes found laterally throughout the thorax and abdomen.
2.The number of spiracles is smaller than the number of stomata.	2. The number of stomata is more than spiracles.
3. Stomata are surrounded by guard cells and do not have a tracheal system.	3. Spiracles are encircled by hairs on their periphery and lead to an extensive network of the tracheal system.
