The answer is E. Stomata.<\/p>\n
Spiracles, gills, lungs, and trachea are all respiratory organs that allow animals to breathe. Stomata, on the other hand, are small pores in the leaves of plants that allow gas exchange to take place.<\/p>\n
Spiracles are small openings in the exoskeleton of insects and other arthropods that allow them to breathe. They are usually located on the sides of the abdomen, and they are connected to a network of tubes called tracheae. The tracheae carry oxygen to the tissues of the insect’s body.<\/p>\n
Gills are organs that allow aquatic animals to breathe. They are usually located in the gill chamber, which is a cavity behind the mouth. Gills are made up of thin, feathery filaments that are richly supplied with blood vessels. The blood vessels absorb oxygen from the water and release carbon dioxide into the water.<\/p>\n
Lungs are organs that allow air-breathing animals to breathe. They are usually located in the chest cavity, and they are made up of millions of tiny air sacs called alveoli. The alveoli are surrounded by a network of capillaries. The capillaries absorb oxygen from the air and release carbon dioxide into the air.<\/p>\n
Trachea is a tube that carries air to and from the lungs. It is made up of a series of rings of cartilage that keep it open. The trachea branches into smaller tubes called bronchi, which carry air to the lungs.<\/p>\n
Stomata are small pores in the leaves of plants that allow gas exchange to take place. They are usually located on the underside of the leaf. Stomata open and close in response to light and humidity. When stomata are open, they allow carbon dioxide to enter the leaf and oxygen to leave the leaf.<\/p>\n","protected":false},"excerpt":{"rendered":"
