Document Summary
Acoelomate: animals not having a true coelom (sponges corals, etc). A coelom is a fluid filled cavity that forms the main body cavity of organisms. It is formed by the splitting of the mesoderm of triploblastic. The coelom functions to separate the muscles of the body wall from the gut so the gut can move independent of the body. It also provides an enlarged area for organs to be housed. Algal mats: a layer of algae on the benthic zone. Made by the accumulation of cyanobacteria and sediments. This provided the large nutrient rich aquatic floor for the burrowing animals later in the. Amebocyte: animal cell that is present in the sponge. Its location is not fixed and has the ability to transport nutrients to the pinacoderm from the choanocytes which absorb the food. Archeocyte: the archeocytes form the eggs of sponge cells in female sponge. Basically they are ameobocytes that have become eggs.
