Document Summary

Acoelomate: describing any bilaterally symmetrical animal of the subkingdom. Algal mats: a layer of usually filamentous algae on marine or fresh water soft bottoms. It may be considered one of many types of microbial mats. Amoebocyte: an animal cel whose location is not fixed and is therefore able to wander through the body tissues. Amoebocytes are named after their resemblance, especially in their movement, to amoeba and they feed on foreign partices (including invading bacteria). They occur, for example, in sponges and mammalian blood. (eg some leukocytes) Archenteron: a cavity within an animal embryo at the gastrula stage of development. All or part of the archenteron eventually forms the cavity of the gut. It is connected to the outside by an opening (the blastopore), which becomes either the mouth, the mouth and anus or the anal opening of the animal. Archeocyte: archaeocytes or amoebocytes are amoeboid cells found in sponges.
