Sponges are invertebrate animals that usually have no body symmetry and never have tissues or organs. Cnidarians use stinging cells to capture food and defend themselves. Flatworms are flat and as soft as jelly. Unlike cnidarians or flatworms, roundworms have a digestive system that is like a tube, open at both ends. Earthworms and other segmented worms have bodies made up of many linked sections called segments.
What is the similarities between sponge and the gaseous state?
Both sponges and the gaseous state share the characteristic of having a high degree of flexibility and adaptability. Sponges can change shape and volume to accommodate their environment, much like gases expand to fill the space available to them. Additionally, both can hold large amounts of water (in the case of sponges) or occupy significant volumes (in the case of gases) while maintaining a relatively low density. Finally, both are capable of allowing the flow of materials through their structure, facilitating the movement of nutrients and gases.
