Golgi apparatus. Golgi apparatus. The stacks of flattened membranous vesicles are called Golgi apparatus. It basically
stores, packs and modifies the products in vesicles
. It temporarily stores protein that moves out of the cell through the vesicles of the Golgi apparatus.
What is the function of Golgi apparatus class 9th?
Golgi Bodies Functions
Its main function is
the packaging and secretion of proteins
. It receives proteins from Endoplasmic Reticulum. It packages it into membrane-bound vesicles, which are then transported to various destinations, such as lysosomes, plasma membrane or secretion.
What is Golgi apparatus short answer?
(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 Golgi apparatus in biology?
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.
What is the structure and function of Golgi apparatus Class 9?
1)They are
involved in synthesis of cell wall,plasma membrane and lysosomes
. 2)It produces vacuoles which contain cellular secretions eg:enzymes,protein,cellulose etc. 3)They act as an area for storage,processing and packaging of various cellular secretions.
What is Plasmolysis Class 9?
Plasmolysis is
the process in which cells lose water in a hypertonic solution
. … Through observation of plasmolysis and deplasmolysis, it is possible to determine the tonicity of the cell’s environment as well as the rate solute molecules cross the cellular membrane.
What is the main function of mitochondria Class 9?
The prime function of mitochondria is
to produce energy
. It is the power generation plant where the nutrients turn into ATP by a chemical process. The other major roles played by mitochondria are carrying out cellular metabolism.
What are cisterns Class 9?
Answer:
A reservoir or a closed space filled with body fluid like chyle, lymph, or cerebrospinal fluid etc
is called cistern.
What is the function of ribosomes Class 9?
Functions of ribosomes: Ribosome
provides space for the synthesis of proteins in the cell
. Hence are called protein factories of the cell. Ribosome furnishes enzymes and factors needed for the formation of polypeptides.
What is an example of Golgi body?
The Golgi apparatus has several functions, including modification of several products from the endoplasmic reticulum (ER). Examples include
phospholipids and proteins
. The apparatus can also manufacture its own biological polymers. The Golgi complex is capable of both disassembly and reassembly during mitosis.
How does the Golgi apparatus work?
The Golgi apparatus receives proteins and lipids (fats) from the rough endoplasmic reticulum. It
modifies some of them and sorts, concentrates and packs them into sealed droplets called vesicles
.
What are the two main functions of the Golgi apparatus?
It has been likened to the cell’s post office. A major function is
the modifying, sorting and packaging of proteins for secretion
. It is also involved in the transport of lipids around the cell, and the creation of lysosomes. The sacs or folds of the Golgi apparatus are called cisternae.
What is osmosis Class 9?
Osmosis is the
spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration
, in the direction that tends to equalize the solute concentrations on the two sides.
What is nucleus in biology class 9?
The nucleus is
small, round and membrane bound structure found in cell
. The fluid inside the nucleus surrounded by nuclear membrane is called nucleoplasm. It controls the cell’s growth and reproduction because it contains cell’s hereditary information. It is covered by dual layer called nuclear membrane.
What is a Nucleoid Class 9?
Nucleoid is
the undefined nuclear region containing only nucleic acids
, in the prokaryotic cells. It is not bounded by a nuclear membrane and lies in direct contact with the cytoplasm. … It transports the material in and out of the cell. It is also reponsible for the formation of lysosomes.
What is plasmolysis with diagram?
(a) Plasmolysis can be defined as the
shrinkage of the cytoplasm of a plant cell
, away from its cell wall and toward the centre. It occurs because of the movement of water from the intracellular space to the outer-cellular space.
