Plants lack nervous system.
The phylum Cnidaria encompasses over nine thousand aquatic species. All of these species share common characteristics such as being invertebrates and having no major systems. For example, instead of having a complex nervous system, cnidarians have something called a nerve net which is a simple nervous system. They lack a brain and cephalisation which means the concentration of sensory organs in the head region. However, a nerve net allows the organism to have a response to its environment. In the middle of the nerve net is a nerve ring which allows the cnidarian to swim. An example of an organism with a nerve net is a Hydra.
