The Golgi apparatus is a central intracellular membrane-bound organelle with
key functions in trafficking, processing, and sorting of newly synthesized membrane and secretory proteins and lipids
. To best perform these functions, Golgi membranes form a unique stacked structure.
What is the function of the Golgi?
A stack of small flat sacs formed by membranes inside the cell’s cytoplasm (gel-like fluid). The Golgi complex
prepares proteins and lipid (fat) molecules for use in other places inside and outside the cell
. The Golgi complex is a cell organelle. Also called Golgi apparatus and Golgi body.
What is the structure of the Golgi?
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
. It is located in the cytoplasm next to the endoplasmic reticulum and near the cell nucleus.
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 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 are the four functions of the Golgi apparatus?
- Absorption of compounds: …
- Formation of secretory vesicles and secretion: …
- Helps in enzyme formation: …
- Production of hormones: …
- Storage of protein: …
- Formation of acrosome: …
- Formation of intracellular crystals: …
- Milk protein droplet formation:
What is the main function of lysosomes?
Lysosomes function as
the digestive system of the cell
, serving both to degrade material taken up from outside the cell and to digest obsolete components of the cell itself.
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 is Golgi apparatus explain?
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.
What are three functions of lysosomes?
A lysosome has three main functions:
the breakdown/digestion of macromolecules
(carbohydrates, lipids, proteins, and nucleic acids), cell membrane repairs, and responses against foreign substances such as bacteria, viruses and other antigens.
Why is the Golgi apparatus the most important?
Why the Golgi Apparatus is THE most important organelle
The Golgi Apparatus is important
because it processes and packages protein and lipid
. without the golgi apparatus you would lose your DNA, because DNA is composed of protein.
What is the main function of endoplasmic reticulum?
The endoplasmic reticulum can either be smooth or rough, and in general its function is
to produce proteins for the rest of the cell to function
. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.
What are the two major functions of lysosomes?
- Intracellular digestion: …
- Removal of dead cells: …
- Role in metamorphosis: …
- Help in protein synthesis: …
- Help in fertilization: …
- Role in osteogenesis: …
- Malfunctioning of lysosomes: …
- Autolysis in cartilage and bone tissue:
What are the two functions of lysosomes?
Lysosomes are involved with various cell processes. They
break down excess or worn-out cell parts
. They may be used to destroy invading viruses and bacteria. If the cell is damaged beyond repair, lysosomes can help it to self-destruct in a process called programmed cell death, or apoptosis.
What is the structure and function of lysosomes?
“Lysosomes are sphere-shaped sacs filled with hydrolytic enzymes that have the capability to break down many types of biomolecules.” In other words, lysosomes are membranous organelles whose specific function is
to breakdown cellular wastes and debris by engulfing it with
hydrolytic enzymes.
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.
