ANIMAL CELL STRUCTURE AND CELL PLANT
A. PURPOSE1 . Observing the structure of animal cells and plant cells .2 . Distinguish the structure of animal cells and plant cells .3 . Identifying the structure function of the cell organelles .
B. BASIC THEORYCell was first discovered by Robert Hooke in 1665 , which was first observed cork cells ( Querqus Subber ) . Structure that appears is a box shape . The results Matheas cells followed by J. Theodora Schleiden and Schwann in 1838 , observing living cells turns cell structure is not just a box , and in it there is a liquid that is then continued cell research . The results are contained in the liquid cell organelles that have specific functions . Organelles are the nucleus , mitokondrea , ribosomes , endoplasmic reticulum , Golgi bodies , lysosomes , centrosome , plastids , etc. . Each organelle has a specific function .
C. TOOLS and MATERIALS1 . Microscope 8 . cork2 . Glass objects 9 . shallots3 . Glass deck 10 . Epithelium in the cheek cavity4 . Razor 11 . Methyl blue / gensen vinlel5 . Tweezers 12 . toothpick6 . Needle 13 . Lugol7 . Pipette 14 . Tissue / flannel
D. HOW TO WORK
Take the cork , slice crosswise with a razor blade repeatedly to obtain thin incision . Then put preparations on glass objects , used as drops of water cover with glass deck . Then observed with weak magnification ( 10x10 ) . Image . Observe denmgan 10 x 40 magnification , image and give testimony .
Take onion epidermis with tweezers , then place it on a glass object . Used as drops with Lugol , deck lid with glass . Then observed with weak magnification ( 10x10 ) . Image . Observe denmgan 10 x 40 magnification , image and give testimony .
Take cavity epithelium in the inner cheek with a clean toothpick and has been blunted . Slowly scratched into the inside of the cheek . Put the glass object , used as drops with methyl blue , deck lid with glass . Observed with a microscope with a magnification initially weak , then with strong magnification . Image cell shape , cell sumlah in units of the field of view , as well as give information .
F. DISCUSSION & QUESTIONS
Based on your observations , indicate that the observed cell section !
answer:
cork cells
space between cells
cell wall
cell cavities
onion epidermal cells
cell wall
cytoplasm
cell nucleus
epithelial cells
cell wall
cytoplasm
intisel
Explain the difference between dead cells to live cells !
Dead cells have no cell nucleus ( the cork cells ) , while the living cell has a cell nucleus ( in onion epidermal cells and epithelial cells ) that define life .
3 . Explain the difference between animal cells and plant cells ?
answer:
In plant cells there is a cell wall , whereas animal cells there is no cell wall .
In plant cells there glioksisom , whereas in animal cells there glioksisom .
In plant cells contained plastids , whereas in animal cells is not contained plastids .
In plant cells contained vacuoles , while animal cells are not contained vacuoles .
What is the function of staining with Lugol and Methyl blue ?
answer:To facilitate observation of the cell nucleus ( nucleus ) of a cell under a microscope microscopically
Look for information about cell parts and their functions , and electron micrograph images of cells results !
answer:
Cell parts and their functions :
plasma membrane
protects the cell contents .
regulate entry and exit of molecules .
receive stimuli from outside the cell .
cytoplasm
The storage of chemicals is essential for cell metabolism .
Venue for the demolition activities and preparation of substances through chemical reactions .
Ensuring the exchange of substances that metabolism going well .
nuclei
Controls all cell activities .
Issued and unit ribosomal RNA from the nucleus to the cytoplasm .
Carry genetic imformasi because it contains DNA .
centrioles
regulate polarity ( polar ) animal cell division .
Regulate chromosome segregation during cell division .
endoplasmic reticulum
Protein synthesis reservoir for distribution to the Golgi complex and eventually expelled from the cell .
Synthesizing proteins and cholesterol .
Offering poison ( detiksifikasi ) .
Road transport to move molecules from one part of the cell to the other cells .
ribosomes
Synthesize protein .
Golgi body
Forming pockets ( vesicles ) for secretion , especially in the gland cells .
Form the plasma membrane .
Forming the walls of plant cells .
Forming aksorong on spermatozoa that contain enzymes to break down the cell walls and the formation of lysosomes eggs .
lysosomes
Digest macromolecules and destroy foreign cells .
Peroxisome and Glioksisom
Perosisom berfingsi convert fats into carbohydrates dengam help of the enzyme catalase .
Glioksisom function convert fat into sugar .
mitochondria
Energy -producing cells .
plastids
Organelles that contain pigments .
vacuole
Place food reserves .
Save pigment .
Storing essential oils .
Save the rest of metabolism .
cytoskeleton
Provide mechanical strength to the cell .
Be the cell skeleton
The substance helps the movement of cells from one part to another part .
