Why do Cnidaria not need respiratory or excretory systems?
Cnidarians, such as jellyfish and corals, do not require specialized respiratory or excretory systems because of their simple body structure and the environments in which they live. They have a high surface area-to-volume ratio, allowing for efficient diffusion of gases (oxygen and carbon dioxide) directly through their cell membranes. Additionally, their body fluids can help in the removal of waste products, eliminating the need for complex excretory organs. This simplicity is well-suited to their aquatic habitats where diffusion is effective.
