👉 Endotrophic refers to a type of tissue that is involved in the exchange of nutrients and oxygen between different parts of an organism. This can be found in plants, animals, and fungi, as well as in some bacteria. In plants, endotrophs are known as stomata or xylem vessels, which allow water and other substances to pass through them into the air. In animals, they are known as gut contents or excretory organs, where waste products and nutrients are produced
