To view a micrograph of ER interpreted using the Gridpoint cross-hairs device, click here. This statement certainly applies to the endoplasmic reticulum an organelle found in eukaryotic cells. Many of these products are made for and exported to other organelles. This is an electron microscope image showing part of the rough endoplasmic reticulum in a plant root cell from maize. The dark spots are ribosomes. There are two types of endoplasmic reticulum: rough endoplasmic reticulum rough ER and smooth endoplasmic reticulum smooth ER. Both types are present in plant and animal cells.

The difference lies between the two is that the Smooth Endoplasmic Reticulum is not bounded by the ribosomes and is known for storing the lipids and proteins. Meanwhile, the Rough Endoplasmic Reticulum is bounded by the ribosomes and store proteins. The another most essential component of the eukaryotic cell is the Endoplasmic Reticulum or ER. It occupies almost 10 percent of the total cell volume. ER is of two type smooth and rough. Though both share some common features too but differ in some.

Endoplasmic reticulum ER , in biology , a continuous membrane system that forms a series of flattened sacs within the cytoplasm of eukaryotic cells and serves multiple functions, being important particularly in the synthesis, folding, modification, and transport of proteins. All eukaryotic cells contain an endoplasmic reticulum ER. In animal cells, the ER usually constitutes more than half of the membranous content of the cell. Differences in certain physical and functional characteristics distinguish the two types of ER, known as rough ER and smooth ER. The morphological distinction between the two is the presence of protein-synthesizing particles, called ribosomes , attached to the outer surface of the RER. The functions of the SER, a meshwork of fine tubular membrane vesicles, vary considerably from cell to cell, one important role being the synthesis of phospholipids and cholesterol , which are major components of the plasma and internal membranes.

Smooth and rough ER are two types of endoplasmic reticulum, which develop an interconnected system consisting of membrane-bound channels in the cytoplasm of the cell. ER is a membrane-enclosed organelle found only in eukaryotic cells. The ER is composed of a membrane network called cisternae. Its rough appearance is given by the bound ribosomes on its surface. Rough ER synthesizes and stores proteins. Smooth ER, on the other hand, helps in the storage of proteins and lipids.

Endoplasmic reticulum ER is an organelle found in both eukaryotic animal and plant cells. Endoplasmic reticulum exists in two types that is; rough endoplasmic reticulum and smooth endoplasmic reticulum. The two types of ER often appear as if separate, but are sub-components of the same organelle. Rough ER and smooth ER can be differentiated from one another based on their appearance and function. Rough endoplasmic reticulum is involved in protein synthesis, protein folding, protein quality control and dispatch. On the other hand, smooth endoplasmic reticulum is associated with the production and metabolism of fats and steroid hormones. In many cases, cells specializing in the production of proteins will tend to have a larger amount of rough endoplasmic reticulum while cells producing lipids and steroid hormones will have a greater number of smooth endoplasmic reticulum.
