Structure dabba cell

Cell - da karami Tsarin duk shuka da dabbobi rai - mafi m sabon abu yanayi. Ko a ranar da kansa matakin da shi ne musamman wuya cell da aka shirya da kuma daukar wani jam'i na Tsarin cewa yin takamaiman ayyuka. A cikin jiki, wani takamaiman sa na Kwayoyin samar da kyallen takarda, kyallen takarda - gabobin, da waɗanda - jiki da tsarin. A tsarin da dabba da shuka Kwayoyin a mutunta mutane da yawa irin wannan ba, amma a lokaci guda kuma yana da muhimman hakkokin bambance-bambance. Alal misali, kamar sunadarai abun da ke ciki na sel, irin wannan ka'idojin tsarin da kuma aiki, amma a shuka Kwayoyin suna da centrioles (sai algae), da kuma matsayin da sinadirai musanya tushe ne sitaci.

A tsarin da Kwayoyin na dabba bisa uku main aka gyara - da tsakiya, cytoplasm da jikin tantanin. A cikin ainihin cytoplasm suranta protoplasm. Cell membrane - shi ne mai nazarin halittu membrane (septum) wanda ya raba cell daga waje yanayi, shigar da kwayoyin halitta da kuma nuclei Forms cytoplasmic compartments. Idan ka sanya shirye-shiryen karkashin madubin, da tsarin da dabba cell za a iya sauƙi gani. Cell membrane qunshi uku yadudduka. A m da ciki yadudduka da furotin da kuma na tsaka-tsaki - sia. Cikinsa da lipid Layer kara ne zuwa kashi biyu yadudduka - a Layer na hydrophobic kwayoyin da wani Layer na hydrophilic kwayoyin, wanda aka shirya a wani takamaiman tsari. A surface na jikin tantanin tsari ne na musamman - glycocalyx, wanda ya samar da da ikon zabe membrane. A harsashi wuce da zama dole kayan da kuma riko da wadanda suka zo da wata cũta. A tsarin da dabba cell ne da nufin tabbatar da m aiki ne riga a wannan matakin. A shigar azzakari cikin farji daga abubuwa ta hanyar da harsashi na faruwa ne ta kai tsaye hannu na cytoplasmic membrane. A surface na membrane ne muhimmi da isasshen saboda bends, protrusions, folds da kuma villi. A cytoplasmic membrane wuce kamar yadda mafi karami barbashi da kuma girma.

A tsarin ne halin dabba cell cytoplasm, domin mafi yawan bangare kunshi ruwa. A cytoplasm - matattarã ga wasu gabbansa da inclusions. Bugu da ƙari cytoplasm ƙunshi cytoskeleton kuma - gina jiki filaments cewa suna da hannu a aiwatar da cell division, delimit cikin kwayuka sararin samaniya da kuma kula da cell siffar, da ikon ji ƙyama. An muhimmin bangaren da cytoplasm - hyaloplasm wanda kayyade danko da kuma elasticity daga cikin cell tsarin. Dangane da waje da kuma ciki dalilai hyaloplasm iya canza ta danko - don zama wani ruwa ko gel.

Nazarin tsarin da dabba cell, ba shi yiwuwa ba a kula da salon salula kayan - wasu gabbansa da aka samu a cikin cell. Duk da wasu gabbansa da nasu musamman tsarin, wanda aka sa ta cikin ayyukan yi. A tsakiya - tsakiya naúrar na cell cewa ya ƙunshi bayanin Halittar jini da aka hannu a metabolism a cikin cell kanta. By salula da wasu gabbansa hada da endoplasmic reticulum, da cell cibiyar, mitochondria, ribosomes, Golgi hadaddun, plastids, lysosomes, vacuoles. Wadannan wasu gabbansa ne a kowane cell, amma, dangane da aikin, da tsarin da dabba cell iya bambanta da gaban takamaiman Tsarin.

Aiki kwayoyin halitta:

- mitochondria oxidize gudanar da mahadi da kuma accumulates sinadaran makamashi.

- endoplasmic reticulum saboda gaban na musamman enzymes hada fats da kuma carbohydrates, shi Ciyarwar sauƙaƙe kai na abubuwa a cikin Kwayoyin.

- ribosome haduwa gina jiki.

- Golgi hadaddun gina jiki fi mai da hankali, condenses roba fats, polysaccharides, Forms lysosomes da kuma shirya littattafai don su kau na sel ko kai tsaye amfani a cikin shi;

- lysosomes narkewar carbohydrates, sunadarai, fats da kuma nucleic acid, a gaskiya, digesting shigar da cell gina jiki.

- cell cibiyar da aka hannu a kan aiwatar da cell division.

- vacuole, saboda da abun ciki na cell sap support cell turgor (ciki matsa lamba).

A tsarin da rayayyun tantani ne musamman wuya - a salon salula matakin daukan mai yawa biochemical matakai, wanda sovvokupnosti samar da muhimmanci ayyuka na jiki.
