The endoplasmic reticulum (ER) is a synthesis and transport organelle that branches into the cytoplasm in plant and animal cells. The Golgi apparatus is a series of multiple compartments where molecules are packaged for delivery to other cell components or for secretion from the cell.
Why Golgi apparatus is called the delivery system?
While many types of cells contain only one or several Golgi apparatus, plant cells can contain hundreds. The Golgi apparatus is responsible for transporting, modifying, and packaging proteins and lipids into vesicles for delivery to targeted destinations.
What organelle functions as a delivery system?
Golgi apparatus
Computer illustration of Golgi apparatus. This organelle functions as a central delivery system for the cell. Its primary function is to modify, store and transport proteins and lipids made elsewhere in the cell.
How a cell works like a factory?
A cell can be thought of as a “factory,” with different departments each performing specialized tasks. A cell’s plasma membrane regulates what enters or leaves the cell. The cytoplasm is similar to the factory floor where most of the products are assembled, finished, and shipped.
What is the main function of Golgi body?
A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell. Named after its discoverer, Camillo Golgi, the Golgi body appears as a series of stacked membranes.
How many Golgi bodies are in a cell?
The number of compartments in any one Golgi apparatus is usually between 3 and 8. The number of sets of Golgi apparatus in a cell can be as few as 1, as in many animal cells, or many hundreds as in some plant cells.
Which is the delivery system of the cell?
The cell’s delivery system is called the endoplasmic reticulum. Two types of endoplasmic reticulum exist in a cell: rough and smooth.
Which is the best description of a drug delivery system?
Abstract Drug delivery systems (DDS) are defined as methods by which drugs are delivered to desired tissues, organs, cells and subcellular organs for drug release and absorption through a variety of drug carriers.
Which is the correct definition of gene delivery?
Gene delivery. Gene delivery is the process of introducing foreign genetic material, such as DNA or RNA, into host cells.
Are there any nonviral delivery systems for gene therapy?
Although numerous viral and nonviral gene delivery systems have been developed in the last 3 decades, no delivery system has been designed that can be applied in gene therapy of all kinds of cell types in vitro and in vivo with no limitation and side effects.
