8. What would happen to the life of cell if there was no golgi complex? (AS 2) 9. When you are observing the nucleus of cheek cell in laboratory, what precautions do you take ? 10. Read the chapter carefully collect the information about the functions of different cell organelles and make a table which contains serial number. Cell organelle and their function. Don't forget to write your specific findings below the table? (AS 4)

Answer:
Hint: Golgi apparatus is an organelle found in most eukaryotic cells. It is a part of the endomembrane system in the cytoplasm. It packages proteins into membrane-bound ventricles inside the cell before the vesicles are sent to their destination.
Complete answer: If there were no Golgi bodies, the proteins in cells would float around without direction. Other cells and organs in the body would not function properly without the products that the Golgi body normally sends. In the absence of the Golgi apparatus, lysosomes would not be produced, and the accumulation of dead and damaged organelles and molecules in the cell would ultimately result in cell death. As the distribution and shipping centre for the cell’s chemical products, the Golgi apparatus alters proteins and lipids and gets them ready for transport to other locations within or outside the cell. The Golgi apparatus processes proteins for secretions that contain enzymes that attach sugar monomers to proteins. If the Golgi apparatus is not present the packaging and transport of materials would cease. The secretory activities of the cell would also cease. The acrosome develops during the spermatogenesis and is the product of the Golgi complex. If the Golgi apparatus is absent, then acrosome formation doesn’t take place.

9.Human cheek cells are the epithelial cells. These are the tissues that line the inner part of the mouth which is known as the basil mucosa and comprises scaly epithelial cells. Cheek cells are dividing every 24 hours and are continuous falls from the body.
-Cheek cells contain a nucleus and many other organelles which easily fall from the mouth lining and are easy for observation.
Precautions we have to take when observing the nucleus in the cells of the cheek are-
1)Taking out the cheek cell in a very gentle manner with the help of a clean toothpick to avoid any type of injury.
2)Before scraping the tissue, the mouth should be cleaned and rinsed if there are any food particles present in the mouth.
3) Place the coverslip softly to avoid the entry of any air bubble.
4) Always remove extra glycerine with the help of blotting paper.
5) Spread a scrap of cheek cells so that they are properly distributed.
6) The glass slide and coverslip both should be cleaned. The microscope used for observation should also be cleaned. If there will be any smudge remove it from the lenses and wipe it down thoroughly.
Additional Information: once the cells have been obtained the following procedure will be taken for the preparation of cheek cell wet mount
1) Put one drop of saline on a clear microscopic slide.
2)In the center of the slide smear the cells for about 4 seconds to get the cells on the center of the slide
3)On this year put one drop of methylene blue and place it with a coverslip on the top of it.
4) with the help of a paper towel or blotting paper, remove the extra solution
Note: Cheek cells include some of the main parts. they are
1)Cell membrane
2)Cytoplasm
3)Nucleus at the center of the cells which control all the function of cells.
4)Some of the organelle example mitochondria.
10.the name of cell organelles are mitochondria, golgi appratus, ribosomes, lybosomes, ER ( endoplasmic reticulum ), nucleus , vacuole
1. mitochondria function :- it is also known as powerhouse of cell because it provide power to all the cell organelles to work properly
@ it also contain it's own DNA
@ hey provide energy to all cell in the form of ATP ( adenosine triphosphate)
2. Golgi apparatus function:- it is also known as packaging factory of cell because it package and transport the material inside the cell
3. ribosome functions:- it is also known as protein factory of cell because it produce protein with the help of (RER) rough endoplasmic reticulum and form liquid with the help of (SER)
4. lybosomes functions:- it is also known as digestive bags, suicidal bags and destructive enzymes. because it destroy the bacteria or any kind of toxic material in the cell
5.ER( endoplasmic reticulum) function:- it is of two kind first smooth endoplasmic reticulum and second hand of Endoplasmic reticulum.
Smooth endoplasmic reticulum form lipids with ribosomes
Rough endoplasmic reticulum form protein with ribosomes
It it also transport the food in whole cell
6. nucleus function:- it is a brain of cell it give command to whole cell what to perform and what to do at what time is it control all the cell
please like and support me..
7. vacuoles functions:- it is different in animal cell and in plant cell it is smaller or absent in Plant cell and it covers 90% of area in the plant cell at almost IT act as a storage in a plant cell
