Endoplasmic Reticulum
Endoplasmic Reticulum (ER) is a complex network of tubular membranes present within the cytoplasm of the eukaryotic cell, transpiring either with a smooth surface and therefore called as the smooth endoplasmic reticulum or studded with ribosomes and hence called the rough endoplasmic reticulum which is involved in the transportation of materials. These membranes are continuous, joining with the outer membrane of the nuclear membrane. They occur in almost every type of eukaryotic cell except red blood cells an.
Answer:
Explanation:
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 two types of ER often appear as if separate, but they are sub-compartments of the same organelle. Cells specialising in the production of proteins will tend to have a larger amount of rough ER whilst cells producing lipids (fats) and steroid hormones will have a greater amount of smooth ER.
Part of the ER is contiguous with the nuclear envelope. The Golgi apparatus is also closely associated with the ER and recent observations suggest that parts of the two organelles, i.e. the ER and the Golgi complex, are so close that some chemical products probably pass directly between them instead of being packaged into vesicles (droplets enclosed within a membrane) and transported to them through the cytoplasm
