Apoptosis is a type of controlled cell death. It happens throughout development when cells have to be removed. It also gets rid of diseased cells, such as those that are potentially cancerous, or those infected with a pathogen, for example.
Sponges are a type of aquatic animal whose body is covered in tiny pores called ostia. The ostia allow water, oxygen, and other nutrients to flow into the sponge's body, and for waste products like ammonia and carbon dioxide to exit their body. The respiratory system of a sponge is based on the process of diffusion.
