Tsarin da kuma na asali ayyuka na sel

Sel, kamar tubalin a gida ne gini tubalan kusan dukkanin rayayyun kwayoyin halitta. Abin da sassa su ne suka? Mene ne aikin a cikin cell yi wani iri-iri na musamman Tsarin? Wadannan da wasu tambayoyi za ka sami amsoshi a cikin wannan labarin.

Mene ne wani cell

Cell shi ne mafi karami tsarin da kuma aikin naúrar na rayayyun kwayoyin halitta. Duk da mun gwada da kananan size, shi Forms da kansa matakin na ci gaba. Misalai na guda-celled kwayoyin ne kore algae da chlorella chlamydomonas, euglena protozoa, amoeba da infusoria. Su size ne sosai kankanin. Duk da haka, da aiki daga cikin sel na wannan din hadin kai ne wajen rikitarwa. Wannan abinci mai gina jiki, numfasawa, metabolism, motsi a cikin sarari da haifuwa.

sifar tantanin halitta: tebur "Tsari da kuma aiki na da wasu gabbansa"

Wannan tebur za ta taimaka don matsahi na saba da tsarin da cell Tsarin.

Kamar yadda ka gani, kowane cell organelle yana da wani hadadden tsarin. Haka kuma, tsarin kowace daga cikinsu ma'anar da kuma ayyuka. Kawai hadewa aikin na duk wasu gabbansa da damar da wanzuwar rayuwa a cikin salon salula, nama, da kuma kwayoyin matakan.

Babban aiki na cell

Cell - na musamman da tsarin. A daya hannun, kowane na ta bangaren taka rawar a. A gefe - cell aiki ne batun guda jiwuwa inji ayyukansu. Yana da a wannan matakin na kungiyar na rayuwa sanya mafi muhimmanci matakai. Daya daga cikinsu shi ne haifuwa. Ya dogara ne a kan tsari na cell division. Akwai manyan hanyoyi biyu na da shi. Saboda haka, gametes aka raba da meiosis, duk sauran (somatic) - mitosis.

Saboda membrane ne semipermeable, za a iya samu a cikin wani keji da kuma a gaban shugabanci da daban-daban abubuwa. Dalili na duk tafiyar matakai na rayuwa ne ruwa. A cikin jiki, biopolymers cleaved zuwa mafi sauki mahadi. Amma ma'adinai abubuwa ne a cikin bayani a ionic form.

Mene ne nama

A kwayar kwayoyin, Kwayoyin, irin wannan sifa da aiki suna hade a nama. Wannan shi ne na musamman tsarin. Alal misali, duk da sel epithelial nama na kananan, tam dab da juna. Su form ne sosai bambancin. Wannan nama ne kusan babu intercellular abu. Wannan tsarin yayi kama da garkuwa. Saboda wannan epithelial nama ne m. Amma kowane jiki yana bukatar ba kawai "garkuwa", amma kuma da dangantaka da yanayi. Don yin wannan aiki, da kuma a cikin epithelial nama na dabbobi da ilimi na musamman - pores. A irin wannan tsarin a tsire-tsire ne stomata ko lenticels kwasfa stoppers. Wadannan Tsarin yi gas musayar, transpiration, photosynthesis, thermoregulation. Kuma sama da dukan, wadannan matakai suna da za'ayi a cikin kwayoyin da salula matakin.

Da dangantakar tsarin da kuma ayyuka na sel

cell aiki saboda su tsari. All yadudduka ne bayyananne misali na wannan. Saboda haka, myofibrils ne iya rage. Wannan tsoka Kwayoyin, wanda kawo kuma matsar da mutum sassa na dukan jiki a sarari. Kuma a nan a jamsin - da sauran gini manufa. Wannan irin masana'anta kunshi manyan Kwayoyin. Su ne kafuwar dukan kwayoyin. A connective nama kuma ya ƙunshi babban adadin extracellular matrix. Wannan tsarin tabbatar da isasshen. Wannan irin nama da aka gabatar da irin wannan nau'in kamar jini, guringuntsi, kashi nama.

An ce da jijiya Kwayoyin ba regenerate ... A wannan al'amari akwai mutane da yawa daban-daban ra'ayoyi. Amma babu daya shakka cewa neurons gama dukan jiki a guda naúrar. Wannan aka samu da daban-daban tsarin fasali. Neurons kunshi wani jiki da kuma matakai - axons da dendrites.

Saboda haka, mafi rai kwayoyin da salula tsarin. Wadannan Tsarin ne raka'a tsarin shuke-shuke, da dabbobi, da fungi da kwayoyin cuta. Janar ayyuka na sel - ne da ikon su raba, ji wa muhalli dalilai da kuma metabolism.
