Endoplasmic Reticulum: Structure and Function The endoplasmic reticulum is a network of tubules and flattened sacs that serve a variety of functions in the cell. There are two regions of the ER that differ in both structure and function. One region is called rough ER because it has ribosomes attached to the cytoplasmic side of the membrane.The other region is called smooth ER because it lacks attached ribosomes. Typically, the smooth ER is a tubule network and the rough ER is a series of flattened sacs. The space inside of the ER is called the lumen.The ER is very extensive extending from the cell membrane through the cytoplasm and forming a continuous connection with the nuclear envelope.ypically, the smooth ER is a tubule network and the rough ER is a series of flattened sacs.

What is the function of smooth endoplasmic reticulum in plant cell? The smooth endoplasmic reticulum, or smooth ER, is an organelle found in both animal cells and plant cells. An organelle is a sub-unit within a cell that has a specialized function. The main function of the smooth ER is to make cellular products like hormones and lipids. So this is the function of endoplasmic reticulum. 991 Views · View Upvoters

- Photo by: Lemonade. The endoplasmic reticulum (ER) is a series of interconnected membranes or flattened sacs adjacent and connected to the nuclear membrane. The ER comes in two different morphological forms: smooth endoplasmic reticulum (sER) and rough endoplasmic reticulum (rER). The primary function of the sER is to serve as a platform for the synthesis of lipids (fats), carbohydrate (sugars) metabolism , and the detoxification of drugs and other toxins.

Convert from Character Arrays to Numeric Values The functions listed in this table provide a number of ways to convert character strings to numeric data. Function. Description. Example. uintN (e.g., uint8). Convert a character to an integer code that represents that character. 'Hi' → 72 105. str2num. Convert a character type to a numeric type. '72 105' → [72 105]. str2double. Similar to str2num, but offers better performance and works with cell arrays of strings.

- Definition of Endoplasmic Reticulum. Cells have many organelles that work together to help them complete their life functions. One of those organelles is the endoplasmic reticulum, which is an interconnected network of membrane vesicles, or small containers used by cells to transport or hold materials. The surface of the endoplasmic reticulum is basically a workspace for the cell.
