The Golgi apparatus, or Golgi complex, functions as
a factory in which proteins received from the ER are further processed and sorted for transport to their eventual destinations:
lysosomes, the plasma membrane, or secretion. In addition, as noted earlier, glycolipids and sphingomyelin are synthesized within the Golgi.
What are the functions 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 are the main functions of Golgi apparatus?
The Golgi apparatus is responsible for
transporting, modifying, and packaging proteins and lipids into vesicles for delivery to targeted destinations
. As the secretory proteins move through the Golgi apparatus, a number of chemical modifications may transpire.
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 the function and structure of Golgi apparatus?
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 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.
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 chromosomes?
Chromosomes carry the basic genetic material DNA which is responsible to
provide hereditary characteristics and genetic information to the various cells
. The cellular functions are important for the growth and survival of living organisms.
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 cell theory class 9?
Cell theory states that: →
All living organisms are composed of cells
. → Cell is the fundamental unit of life. → All new cells come from pre-existing cells.
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 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.
What does the Golgi apparatus look like?
The Golgi apparatus (GA), also called Golgi body or Golgi complex and found universally in both plant and animal cells, is typically comprised of a series of five to eight cup-shaped, membrane-covered sacs called cisternae that look
something like a stack of deflated balloons
.
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 are the two main functions of chromosomes?
Functions of Chromosomes
The most important function of chromosomes is
to carry the basic genetic material – DNA
. DNA provides genetic information for various cellular functions. These functions are essential for growth, survival, and reproduction of the organisms. Histones and other proteins cover the Chromosomes.
What are the 4 parts of a chromosome?
- Part # 1. Pellicle and Matrix:
- Part # 2. Chromatids, Chromonema and Chromomeres:
- Part # 3. Centromeres (= Primary constriction):
- Part # 4. Secondary Constriction:
- Part # 5. Satellite:
- Part # 6. Telomere:
