WebIt is more tubular than the rough endoplasmic reticulum, and is not necessarily continuous with the nuclear envelope. Every cell has a smooth endoplasmic reticulum, but the amount will vary with cell function. For example, the liver, which is responsible for most of … Web16 feb. 2013 · The endoplasmic reticulum (ER) stress response is a highly conserved mechanism that results from the accumulation of unfolded or misfolded proteins in the ER. The response plays an important role in allowing plants to sense and respond to adverse environmental conditions, such as heat stress, salt stress and pathogen infection. Since …

It is a … WebProkaryote cells lack the typical eukaryote organelles such as Golgi apparatus, endoplasmic reticulum, mitochondria, and chloroplasts.. Although all prokaryote and eukaryote cells have cytoplasm (or cytosol) that contains several membrane-bound bodies. Prokaryotic cells lack organelles such as Golgi apparatus, endoplasmic reticulum, …
WebEndoplasmic reticulum is an organelle found in both eukaryotic animal and plant cells. It often appears as two interconnected sub-compartments, namely rough ER and smooth ER. Both types consist of membrane enclosed, interconnected flattened tubes. The rough ER, studded with millions of membrane bound ribosomes, is involved with the production ... WebThe endoplasmic reticulum (ER) is the eukaryotic cell's transit system and a host of several other tasks such as protein folding. The rough (RER) and smooth endoplasmic reticulum (SER) are two major components of this type of organelles. The endoplasmic reticulum consists of flat membranous sacs known as cisternae and tubular sections.
WebThe Endoplasmic Reticulum in a eukaryotic cell is the transport network of the cell and it extends from and connects the nuclear membrane to the plasma membrane of … WebWhile the two membranes and the endoplasmic reticulum are linked, proteins embedded in the membranes tend to stay put rather than dispersing across the continuum. It is lined …
WebHowever prokaryotes don't use organelles to organise their intracellular space. Evolutionarily, there is evidence that mitochondria and chloroplasts are ancestors of symbiotic prokaryotes. This theory is called the endosymbiotic theory. I've tried to find an evolutionary story that explains other organelles, specifically the endoplasmic reticulum.
WebEndoplasmic reticulum (ER) is a highly convoluted, netlike meshwork that extends throughout the cytoplasm. It is composed of a single membrane and constitutes more than half of the total membrane of the cell. ...
