what is polysaccharide system in golgi body?
Answers
Answer:
The synthesis of these cell wall polysaccharides is a major cellular function, and as much as 80% of the metabolic activity of the Golgi apparatus in plant cells may be devoted to polysaccharide synthesis.
Explanation:
Answer:
Golgi body
The Golgi body (also called Golgi apparatus, or Golgi complex) consists of a series of disk-like membranes (cisternae) organized into stacks, or dictyosomes. Newly synthesized glycoproteins are directed from the ER lumen to the Golgi body for further addition of sugar residues to the oligosaccharide core. These carbohydrate tags serve as signals for sorting and transport of the mature glycoproteins to their appropriate compartments within the cell, or out of the cell. The Golgi body has a distinct polarity, with proteins entering its cis (or entry) face via transport vesicles called transitional elements that bud from the ER, and exiting through its trans face via secretory vesicles

Golgi Complex
The Golgi complex is a cytoplasmic organelle whose specific function in protozoans is essentially identical to that in other eukaryotes. The Golgi is the seat of glycosylation of a number of secretory products of the cell. It is in the cisternae of the Golgi complex, for instance, that the final carbohydrate moieties are added to the glycocalyx associated with the plasma membrane. The arrangement and number of Golgi complexes vary during the life cycle of many protozoans. Thus, cyst-forming protistans may lose their Golgi complexes during encystation, only to resynthesize them when they excyst. The so-called parabasal body of protozoans is homologous to the Golgi complex of other eukaryotic cells but with several morphological differences, the most notable of which is the frequent presence of a fibril, the parabasal filament, running from the cisternae of the Golgi complex to one or more basal bodies.
