Can smooth ER be found in plant cells?
smooth endoplasmic reticulum SER occurs both in animal and in plant cells. The function of the SER can vary, depending on cell type.
Is smooth ER found in all cells?
Definition of the Smooth ER 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.
What type of cells have rough ER?
For instance, cells of the pancreas that produce the protein insulin, have abundant rough endoplasmic reticulum. Plasma cells, white blood cells that secrete immune proteins called antibodies, are so crowded with rough endoplasmic reticulum it is difficult to distinguish other organelles within the cytoplasm.
Where is the rough ER located in the cell?
Rough ER lies immediately adjacent to the cell nucleus, and its membrane is continuous with the outer membrane of the nuclear envelope. The ribosomes on rough ER specialize in the synthesis of proteins that possess a signal sequence that directs them specifically to the ER for processing.
What does the rough ER do in a plant cell?
The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.
Is rough ER found in animal or plant cells or both?
The endoplasmic reticulum is a network of tubules and flattened sacs that serve a variety of functions in plant and animal cells. There are two regions of the ER ER A TV medical drama that overlooks and chronicles the daily personal/working lives of a team of ER Doctors, Nurses, Patients and the people around them who work in Cook County General Teaching Hospital. Through this we see the heartbreak, triumph, loss and love they experience and sacrifi… 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.
What does the smooth ER do in a 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.
Do plant cels heal the plant?
Plants stem cells come from…you guessed it…plants. These stem cells heal the plant . If you break off a plant stem, it can grow back thanks to stem cells. However, UNLIKE human stem cells, the growth factors, cytokines and other proteins, do not have the ability to act the same way in humans, as in plants. In skincare, plant stems cells can provide only moderate benefits.
What cells are rough ER found in?
Rough endoplasmic reticulum (RER), series of connected flattened sacs, part of a continuous membrane organelle within the cytoplasm of eukaryotic cells, that plays a central role in the synthesis of proteins.
