how to transport the nutrients and other materials in cnidarians explain it
Answers
Answer:Cnidarians are the one of the most simplest of organisms and they do not have a closed or open circulatory system,. Their circulatory system does not have any circulatory vessels. They mostly use diffusion as their means of circulating materials through their bodies. Diffusion is the most simplest form of circulating materials. The purpose of a circulatory system is to transport oxygen and nutrients, which the cells of that organism need, and remove waste. In a cnidaria, all the cells have contact with the water, which is full of oxygen and nutrients that the animal requires. Cnidarians have a very primitive gastrovascular cavity that utilizes diffusion to spread the needed materials and nutrients to other parts of the body. This gastrovascular cavity acts as a digestive cavity where diffusion and distribution of the required substances can occur. This cavity attempts to help the process of diffusion by reducing the distance a substance must diffuse to enter and leave the cell, through its large surface area in the organism. The animals contain two layer and a jelly-like mesoglea. Some cnidarians do contain three different systems: the nervous, reproductive, or the digestive.
