Secretory vesicles form from the trans Golgi network, and they release their contents to the cell exterior by exocytosis in response to extracellular signals. The secreted product can be either a small molecule (such as histamine) or a protein (such as a hormone or digestive enzyme).
What are Idiosomes?
Medical Definition of idiosome : any of several specialized cellular organelles: as. a : acrosome. b : an area of modified cytoplasm surrounding a centrosome.
What is Lipochondria?
Lipochondria is the temporary storage vacuoles of lipids in the Golgi apparatus. Various workers have given various names to this complex, like dictyosome, idiosome, lipochondria, Golgi body, Golgi substance, Golgi body, and Golgi complex.

What does secretory vesicles secrete?
The secretory vesicle is a vesicle that mediates the vesicular transport of cargo – e.g. hormones or neurotransmitters – from an organelle to specific sites at the cell membrane, where it docks and fuses to release its content.
Which of the following is are functions of Lipochondria?
(I)Chemical modification of lipids and proteins. (II) Detoxification. (III) Formation of acrosome. (IV) Glycogen synthesis & breakdown.
Which of the statement is incorrect about Golgi complex *?
– Aid in the formation of plant cell walls: Golgi bodies of plant cells synthesize all types of polysaccharides such as pectin, hemicellulose, and microfibrils of a-cellulose. Therefore the first statement (option a) regarding the function of the Golgi apparatus is incorrect.
What is another name of Golgi body?
The Golgi apparatus, also called Golgi complex or Golgi body, is a membrane-bound organelle found in eukaryotic cells (cells with clearly defined nuclei) that is made up of a series of flattened stacked pouches called cisternae.
What is the relationship between the Golgi apparatus and the cell membrane?
The Golgi apparatus is part of the membrane system that also contains the ER. It consists of stacked membrane-coated cavities, called dictyosomes (Fig. 1.4B). The Golgi apparatus is located close to the nucleus and can be very large in secretory cells, where it fills almost the complete cytoplasm.
The Golgi apparatus gathers simple molecules and combines them to make molecules that are more complex. It then takes those big molecules, packages them in vesicles, and either stores them for later use or sends them out of the cell. It is also the organelle that builds lysosomes (cell digestion machines).
What is the function of Golgi vesicle?
Functions of Golgi Apparatus Golgi vesicles are often, referred to as the “traffic police” of the cell. They play a key role in sorting many of the cell’s proteins and membrane constituents, and in directing them to their proper destinations.
