Can smooth ER be found in plant and animal cells?
SER occurs both in animal and in plant cells.
Is the smooth ER in animals or plants?
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.
What is a smooth ER in a plant cell?
= Endoplasmic reticulum is a network of membranes inside a cell through which proteins and other molecules move. Proteins are assembled at organelles called ribosomes.
What does the smooth ER do in a animal cell?
The smooth endoplasmic reticulum functions in many metabolic processes. It synthesizes lipids, phospholipids as in plasma membranes, and steroids. Cells that secrete these products, such as cells of the testes, ovaries, and skin oil glands, have an excess of smooth endoplasmic reticulum.
Where is the smooth ER found?
Smooth endoplasmic reticulum (sER) is (a part of) endoplasmic reticulum that is tubular in form and lacks ribosomes. It is present in eukaryotic cells and is associated with lipid synthesis, carbohydrate metabolism, regulation of calcium concentration, and drug detoxification.
Where is the smooth ER located in an animal cell?
The smooth endoplasmic reticulum like the rough endoplasmic reticulum is connected to the nuclear envelope. The smooth endoplasmic reticulum comprises tube-like structure located near the cell periphery. These tubules or tubes sometimes branch forming a network that is reticular in appearance.
Is the rough ER in plant and animal cells?
RER occurs in both animal and plant cells. The RER membrane is continuous with the nuclear envelope, which surrounds the cell nucleus.
What organelles does smooth ER work with?
It works closely with the Golgi apparatus, ribososmes, mRNA, and tRNA. Structurally, the endoplasmic reticulum is a network of membranes found throughout the cell and connected to the nucleus.
What are the three functions of smooth endoplasmic reticulum?
Its main functions are the synthesis of lipids, steroid hormones, the detoxification of harmful metabolic byproducts and the storage and metabolism of calcium ions within the cell. The smooth ER is distinguished from the other parts of the endoplasmic reticulum by the absence of membrane-bound ribosomes.
In which cell would you find the most smooth ER?
liver cells
Large amounts of smooth endoplasmic reticulum are found in cells that specialize in lipid metabolism. For instance, liver cells remove alcohol and drugs from the bloodstream. Liver cells have an impressive network of smooth endoplasmic reticulum.
What are the functions of smooth ER?
Smooth Endoplasmic Reticulum Function: Smooth ER is responsible for the synthesis of essential lipids such as phospholipids and cholesterol. Smooth ER is also responsible for the production and secretion of steroid hormones. It is also responsible for the metabolism of carbohydrates.
Where is the smooth ER located?
cytoplasm
Structure of the Smooth Endoplasmic Reticulum The Smooth endoplasmic reticulum, as opposed to the rough endoplasmic reticulum, lacks ribosomes on its surface, hence the distinct name. Smooth ER is connected to the nuclear envelope and spreads throughout the cytoplasm.
Is smooth ER found in plant or animal cells?
T he smooth endoplasmic reticulum, or smooth ER, is an organelle found in both animal cells and plant cells. It is described as ‘smooth’ to distinguish it from rough ER, which has ribosomes for protein synthesis on its surface. Each organelle in the cytoplasm of a cell is responsible for performing a certain function. Are ER found in animal cells?
What is smooth endoplasmic reticulum?
T he smooth endoplasmic reticulum, or smooth ER, is an organelle found in both animal cells and plant cells. It is described as ‘smooth’ to distinguish it from rough ER, which has ribosomes for protein synthesis on its surface. Each organelle in the cytoplasm of a cell is responsible for performing a certain function.
What does the rough ER do in a plant cell?
The rough ER, studded with millions of membrane bound ribosomes, is involved with the production, folding, quality control and despatch of some proteins. Smooth ER is largely associated with lipid (fat) manufacture and metabolism and steroid production hormone production. It also has a detoxification function. What does the ER do in a plant cell?
What are the similarities between plant and animal cell architecture?
Both plant and animal cells have similar types of architecture. They are made up of cell boundaries, cytoplasm, nucleus and several cellular organelles. 1. Non-living, rigid, outer boundary.
