Parazoans are a group of animals, mainly sponges, that are considered to be on the evolutionary line closest to animals but lack true tissues. 🧽 Think of them as a bridge between single-celled organisms and more complex animals. They don't have organs like your heart or brain. Instead, they have specialized cells that perform different functions. They're basically organized groups of cells working together without forming true tissues. They represent a unique branch on the animal family tree. It is like a team project where each person has a role but they do not combine their work into a single final product.
