There are ten parts of the endomembrane system: Nuclear envelope, nuclear pore, ribosomes, smooth indoplasmic rediculum, secretory vesicle, lysosome, plasma membrane, and the Golgi apparatus. The endomembrane system during carposporogenesis inChondria tenuissima was studied using electron microscopy and histochemistry. Profiles of the nucleus are convoluted, resulting in a highly increased surface area. Stacked cisternae are found within the peripheral part of the nucleus. Vesicles, tubules and membrane bound fibrillar bodies occur within the nucleoplasm. The endoplasmic reticulum surrounds the nuclear envelope.
The endoplasmic reticulum and the Golgi apparatus, together with small transition vesicles, represent a functional unit. They form two different secretory substances during carposporogenesis. In young stages, carbohydrates are produced by normal dictyosomes within large, normal exocytotic Golgi vesicles. They do not react positively with PAS or Thiéry method and are believed to represent cell wall material. In later stages, the central area of the Golgi cisternae becomes filled with electron dense material. The individual cisternae are transformed into cored vesicles at the trans-face of the dictyosomes. The dense core of the vesicles is proteinaceous and stains with coomassie brilliant blue R. The peripheral fibrillar material is polysaccharidic and reacts positively using the Thiéry method. The contents of the cored vesicles are believed to participate in carpospore attachment. The ER gives rise to cytolysosomes in which starch grains are sequestrated and digested. Mucilaginous sacs seem to be similarly formed.
What else can I help you with?
Which is not a function of the endomembrane system of the cell?
In your cell, this is where the endomembrane system comes in a cell image because one is studded with small ribosomes and one is not.
Is mitochondria part of the endomembrane system?
No. The endomembrane system consists of the endoplasmic reticulum and the Golgi apparatus - i.e things that are formed within the cell. The mitochondria was originally formed from a captured bacterial cell - as it has it's own DNA and its own ribosomes (as well as very bacterial like proteins). It is a separate organelle on its own, although it will have connections with the endomembrane system it is not considered part of it.
What is the function of the endomembrane system in cells?
The endomembrane system carries out critical functions in the cellThe endomembrane system is composed of the different membranes that are suspended in the cytoplasm within a eukaryotic cell.The endomembrane system includes the nuclear envelope, the golgi apparatus, lysosomes, endoplasmic reticulum, and some components of the plasma membrane.The endomembrane system is responsible for a variety of important cellular processes that include protein synthesis and transport, lipid transport, metabolism, and poison detoxification.Vesicles are small membrane segments that transfer polypeptides between and within the endomembrane system.The membranes within the endomembrane system differ in basic structure and function despite cooperation to achieve overall cellular needs.vesicle A membrane-bound compartment found in a cell.ribosome Small organelles found in all cells that are involved in the production of proteins by translating messenger RNA.polypeptide A long, continuous, and unbranched peptide. Proteins consist of one or more polypeptides arranged in a biologically functional way and are often bound to cofactors, or other proteins.
Are endomembrane system found within prokaryotic cells?
No, the endomembrane system is a feature of eukaryotic cells. Prokaryotic cells lack membrane-bound organelles, such as the endoplasmic reticulum, Golgi apparatus, and lysosomes, which are characteristic of the endomembrane system in eukaryotic cells. Instead, prokaryotic cells have a simpler internal structure with their DNA located in the nucleoid region and their metabolic processes occurring in the cytoplasm.
What organelle of the endomembrane system associated with the sorting of lipids and proteins for various cellular function are?
The Golgi apparatus is the organelle of the endomembrane system responsible for sorting, modifying, and packaging lipids and proteins for various cellular functions. It receives molecules from the endoplasmic reticulum and then directs them to their final destinations within the cell or for secretion outside the cell.
Can a cell membrane also be called a endomembrane system?
No, the endomembrane system lies between the nuclear envelope and the cell membrane; dis-including both. The Endoplasmic reticulum and the Golgi apparatus are two members of the endomembrane system. Google endomembrane system to get the complete picture.
