What is Cell Class 9?
A cell is the structural and fundamental unit of life. The study of cells from its basic structure to the functions of every cell organelle is called Cell Biology. All organisms are made up of cells. They may be made up of a single cell (unicellular), or many cells (multicellular).
What is cytoplasm Class 9?
The part of the cell which occurs between plasma membrane and nuclear membrane is called cytoplasm. The inner granular mass of cytoplasm is called endoplasm. Cytoplasm consist of an aqueous ground substance called Cytosol which contain variety of cell organelles.,insoluble waste,storage products.
What is the meaning of Golgi bodies?
A stack of small flat sacs formed by membranes inside the cell’s cytoplasm (gel-like fluid). The Golgi body prepares proteins and lipid (fat) molecules for use in other places inside and outside the cell. The Golgi body is a cell organelle.
Why are Golgi bodies important?
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 another word for Golgi apparatus?
The Golgi apparatus is named for its identifier, Italian cytologist Camillo Golgi (1843-1926). It is also called the Golgi body or, in plant cells, the dictyosome. Collectively in the cell, these organelles are known as the Golgi complex.
What is cytoplasm in short answer?
The cytoplasm (also known as cytosol) is the protoplasm of a cell outside the cell nucleus. It is the jelly-like material plus the organelles outside the nucleus, and inside the cell membrane. Many important functions of a cell take place in organelles, which are like bits of machinery for doing many jobs.
What’s another word for cytoplasm?
protoplasm
What is lysosomes in simple words?
A lysosome is a membrane-bound cell organelle that contains digestive enzymes. 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.
How many types of lysosomes are there?
two types
Who first gave the name lysosome?
They were discovered and named by Belgian biologist Christian de Duve, who eventually received the Nobel Prize in Physiology or Medicine in 1974. Lysosomes are known to contain more than 60 different enzymes, and have more than 50 membrane proteins.
Where do lysosomes come from?
Lysosomes originate by budding off from the membrane of the trans-Golgi network, a region of the Golgi complex responsible for sorting newly synthesized proteins, which may be designated for use in lysosomes, endosomes, or the plasma membrane.
