ACTIVITY Gathered in groups, do a search for books Biology and / or cytology. Note the "model" of the formats of the cell organelles. Then, with modeling dough and / or other materials, make the model cell. Compare the model of your group with the other groups and discuss about the functions of these organelles. The cell nucleus is a part of the cell that contains in its interior, a special material - chromosomes. These chromosomes are formed by molecules called deoxyribonucleic acids (DNA). The cell, integrating the actions of all its organelles, microscale performs all functions essential to life, and as living organisms, it interrelates with other functionally. If these inter-relationships are not established smoothly, an imbalance can occur, especially in the process of cell division, which favors the formation of tumors, usually malignant - cancer. To deepen their knowledge about DNA read in this book, Leaves "DNA: the long chain of life" and leaves "What legacy is this? What is Cancer? Cancer is the name given to a set of more than 100 diseases that have in common the uncontrolled growth (malignant) cells that invade the tissues and organs, and may spread (metastasize) to other parts of the body. Dividing rapidly, these cells tend to be very severe and uncontrollable, causing tumor formation (accumulation of cancerous cells) or malignant neoplasms. In contrast, a benign tumor mass located simply means a cell that multiplies slowly and resemble their original tissue rarely pose a risk of life. The different types of cancer correspond to the various cell types of the body. For example, there are several types of skin cancer, because it is formed by more than one cell type. If the cancer starts in epithelial tissues such as skin or mucous membranes, it is termed carcinoma. If begins in tissues, such as bone, muscle, or cartilage is called sarcoma. Other features that differentiate the various types of cancer together are the speed of multiplication of cells and the ability to invade neighboring tissues and organs or distant sites (metastasis).

AKTIVNOST Okupljeni u skupinama, to potraga za knjigama biologije i / ili citološke. Obratite pozornost na "model" od formata iz organela unutar stanice. Zatim, uz modeliranje tijesta i / ili drugim materijalima, napraviti model stanice. Usporedite model vašeg skupini s drugim skupinama i raspravljati o funkcijama tih organela. Stani na jezgra je dio stanice koji sadrži u svojoj unutrašnjosti, posebno materijala - kromosoma. Ti kromosomi se formiraju molekule nazivaju deoksiribonukleinske kiseline (DNA). Stanica, integrirajući akcije svih svojih organela, mikroskopskim obavlja sve funkcije potrebne za život, a kao žive organizme, to interrelates s drugim funkcionalno. Ako ti međuodnos nisu uspostavljena glatko, neravnoteža može dogoditi, osobito u procesu diobe stanica, što pogoduje nastanak tumora, najčešće maligno - rak. Za produbiti svoje znanje o DNA čitati u ovoj knjizi, Leaves "DNK: dugi lanac života" i ostavlja "Što naslijeđe je li to? Što je rak? Rak je naziv za skup od više od 100 bolesti koje imaju zajedničko nekontroliranog rasta (maligne) stanice koje upasti tkiva i organe, i mogu se širiti (metastazirati) u druge dijelove tijela. Podjela brzo, ove stanice imaju tendenciju da se vrlo teškim i nekontrolirano, što uzrokuje formiranje tumora (nakupljanje stanica raka) ili zloćudnih tumora. Nasuprot tome, benigni tumor nalazi masovna jednostavno znači ćeliju multiplicira polako i nalikuju na njihov izvorni tkiva rijetko predstavljaju opasnost života. Različite vrste raka odgovaraju različitim tipovima stanica u tijelu. Na primjer, postoji nekoliko tipova raka kože, jer je formirana za više od jedne vrste stanica. Ako se rak počinje u epitelnim tkivima poput kože ili sluznice, to je nazvao karcinom. Ako počinje u tkivima, kao što su kosti, mišića, hrskavice ili naziva sarkom. Ostale značajke koje razlikuju različite vrste raka zajedno su brzina umnožavanja stanica i sposobnost da napadnu susjedne tkiva i organa ili udaljenih mjesta (metastaze).
