The cell's delivery system is called the endoplasmic reticulum. This structure is a system of tubules, sacs and membranes that may be interconnected. The endoplasmic reticulum is continuous with the membrane of the nucleus as well as the membrane surrounding the cell.Know More
Two types of endoplasmic reticulum exist in a cell: rough and smooth. Ribosomes, structures that make proteins, cling to the rough endoplasmic reticulum, giving it a lumpy appearance. The rough endoplasmic reticulum, or RER, consists mainly of disk-like sacs. The smooth endoplasmic reticulum, or SER, lacks ribosomes on its surface and is composed of mostly tubules.
The SER makes and transports lipids, or fats, out of the cell. The RER transfers proteins from the ribosomes to the outside of the cell or to another structure called the Golgi apparatus to be processed further.Learn more about Cells
The organelles within a cell generally include the nucleus, ribosomes, endoplasmic reticulum, cell membrane and cell wall. Also included are cytoskelteon, cytoplasm, Golgi apparatus, chloroplasts, and mitochondria; and also vacuoles, vesicles and lysosomes. Plants and animal cells are slightly different, with animal cells never containing chloroplasts or cell walls.Full Answer >
There are three bodies responsible for transport in the cell including the endoplasmic reticulum, the vesicles and the cell membrane. The endoplasmic reticulum moves materials within the cell body, while the vesicles move proteins to the cell membrane, and the membrane transports materials in and out of the cell.Full Answer >
The endoplasmic reticulum is an organelle that functions as a manufacturing and packaging center for the cell. Each cell has a smooth endoplasmic reticulum and a rough endoplasmic reticulum.Full Answer >
The cytomembrane system manages access into and out of a cell, recognizes other cells of the body, provides communication with other cells, and supplies structural support. Also known as the plasma or cell membrane system, its function and components vary based on the organism's domain and the cell's complexity.Full Answer >
