What is a Golgi apparatus simple definition?
(GOL-jee A-puh-RA-tus) A stack of small flat sacs formed by membranes inside the cell’s cytoplasm (gel-like fluid). The Golgi apparatus prepares proteins and lipid (fat) molecules for use in other places inside and outside the cell. The Golgi apparatus is a cell organelle. Also called Golgi body and Golgi complex.
What is the definition of Golgi apparatus Class 9?
Golgi apparatus consists of a system of membrane-bound fluid-filled vesicles (flattened sacs) arranged parallel to each other. They arranged in the form of stacks called as cisternae. These cisternae are smooth and flattened in structure. Vesicles membranes have connections with the membranes of Endoplasmic reticulum.
What is Golgi apparatus Class 8?
The Golgi apparatus is a membrane-bound organelle found in most cells. It is responsible for packaging proteins into vesicles prior to secretion and therefore plays a key role in the secretory pathway. The Golgi is made of 5-8 folds called cisternae.
What is Golgi apparatus Class 11?
Hint: Golgi apparatus is a single-membranous cell structure that is found within the cell. In addition, it is concerned with the process of processing and packaging inside the cells. Step by step answer:Golgi apparatus was first observed by Camillo Golgi.
What is Golgi apparatus BYJU’s?
The Golgi apparatus is a major organelle in most of the eukarytoic cells. They are membrane bound organelles, which are sac-like. They are found in the cytoplasm of plant and animal cells. The Golgi complex is composed of stacks of membrane-bound structures, these structures are known as the cisternae.
What is Golgi apparatus Byjus?
What is Golgi apparatus Toppr?
Explanation: Golgi body or the Golgi apparatus is an organelle found in the eukaryotic cells. It is a membrane-bound organelle having a flat membrane-like structure called cisternae. The golgi body was first discovered by Camillo Golgi and was named after him.
Who described Golgi apparatus Class 9?
The existence of the cell organelle which is now known as Golgi apparatus or Golgi complex, or simply as ‘the Golgi”, was first reported by Camillo Golgi in 1898, when he described in nerve cells an ‘internal reticular apparatus’ impregnated by a variant of his chromoargentic staining.
What is Golgi apparatus structure?
The Golgi apparatus is a central intracellular membrane organelle for trafficking and modification of proteins and lipids. Its basic structure is a stack of tightly aligned flat cisternae. In mammalian cells, dozens of stacks are concentrated in the pericentriolar region and laterally connected to form a ribbon.

What is microsomes Mcq?
3. What is microsome? Explanation: Microsomes are small vesicles formed by the breakdown of ER membrane into fragments. Microsomes which are derived from RER are known as rough microsomes while microsomes lacking ribosomes are called smooth microsome.
