Sponges are heterotrophic, which is a characteristic of an animal and not a plant. Sponges are also multicellular, are made up from cells without cell walls, characteristics of the kingdom Animalia and NOT Plante.
Both humans and sponges are made of millions of cells, both need oxygen to survive, both need water and both produce waste products.
The three classes of sponge skeletons are siliceous or glass sponges (Class Hexactinellida), calcareous sponges (Class Calcarea), and sponges with a fibrous protein skeleton (Class Demospongiae). Each class has unique structural characteristics that support the sponge's body.
Some characteristics of sponges are that they are invertebrate animals. They normally are asymmetrical. They never have tissues or organs. They feed through filter feeding. They reproduce asexually and sexually.
Early naturalists mistakenly classified sponges as plants instead of animals because sponges lack typical animal characteristics such as organs, tissues, and mobility. Additionally, sponges were often found attached to rocks or other surfaces, resembling plants rooted in the ground. This led to the initial confusion in classification.
Sponges were once thought to be plants because they exhibit some plant-like characteristics, such as their stationary nature and lack of obvious sensory organs. Additionally, they can resemble certain aquatic plants in appearance.
