About this site

Foraminifera (forams for short) are single-celled protists with shells. Their shells are also referred to as tests because in some forms the protoplasm covers the exterior of the shell. The shells are commonly divided into chambers which are added during growth, though the simplest forms are open tubes or hollow spheres. Being eukaryotic organisms, the Foraminifera cells contain the following organelles: Nucleus - A cell may contain a single nucleus or multiple nuclei Mitochondria Peroxisomes Golgi complex Endoplasmic reticulum Foraminifera (foraminifers or, informally, just forams) are single-celled Modern taxonomies rank the group as a phylum or subphylum.
