The cell is divided into two regions&colon; the endoplasm and the ectoplasm. The ectoplasm and the granular endoplasm are often hard to distinguish. Cytoplasm is well differentiated in to ectoplasm and endoplasm. This protein is found to be an integral part of the endoplasm reticulum membrane. These are more or less tubular and are mostly filled with granular endoplasm. The term granule refers to a small particle within the endoplasm, typically the secretory vesicles. The food so gulped down is gradually digested inside the endoplasm. The nucleus is separated from the endoplasm by the nuclear envelope. In symbiotic species, the algal symbionts are maintained in the endoplasm. The clear ectoplasm is on the outer edges, while the inner endoplasm is more granular. The cytosol makes up the semifluid portion of the endoplasm, in which materials are suspended. Due to the endoplasm being clear, wood particles can often be observed within the organisms. As a mitochondriate, aerobic organism it has many mitochondria in the endoplasm. The unicellular organism's cytoplasm has distinct separations of an ectoplasm (outer) and endoplasm (inner). The endoplasm, like the cytoplasm, is far from static.
