Iiseli iintsholongwane zahluka plant cells: Uphawu lothelekiso

Iiseli eziphilayo iiyunithi ezahlukeneyo taxonomic eziliqela umahluko. Umalunga imilo, ubukhulu kunye ubukho ezinye izakhiwo. Kweli nqaku siza achaze ukuba iiseli iintsholongwane zahluka plant cells, uze uthelekise ubume babo.

Yintoni i iseli

Iseli yeyona iyunithi incinane lwesakhiwo eziphilayo. Oku njalo kuxokwa-"iibhloko zokwakha". Kudityaniswa iinxalenye unit yeseli ngamnye komhlaba, kukho icytoplasm kwaye siyabophelela isakhiwo - organelles. into ungamyeki, imali leyo njalo, ebizwa inclusions.

Ubume plant cells

A isici esasenza plant cells kuba phambi chloroplasts. Oku plastids eluhlaza, phezu engaphakathi apho inkqubo yefotosinthsis. Esi sakhiwo umisela indlela autotrophic yokondla ezi eziphilayo. iiseli bacteria zahlukile plant cells kunye ubukho bezinye organelles. Ngoko ke, ngokuba yokugqibela luphawulwa ubukho vacuoles. Le kwisisu ezaliswe isisombululo zolwelo kwezinto kwezimbiwa.

Amacala plant cells ziyahluka ngokubanzi. Hi xikombiso, le chlamydomonas nobulembu eluhlaza unako ukufikelela-1 mm, kwaye ubude imicu bast zezi iflakisi - 5 mm. -Avareji izityalo ezisuka-15 ukuya microns 60. Abaninzi kubo inokubonwa kuphela neemicroscope ekukhanyeni.

Ngokutsho uhlobo iiseli iintsholongwane zahlukile plant cells: musa ukuba ndindi zaneleyo. Ubude parenchymal phantse ngokulinganayo nobubanzi okanye kancinci kugqithisela. Baya kuba ngundoqo, eli laphu ngoomatshini kunye conductive. iiseli Prozenhimnye anaba ubude, kunye iziphelo zazo zitsolile. Bayinxalenye womthi.

Iintsholongwane: Iinkalo bombutho

iiseli bacteria zahlukile plant cells, a ubukhulu incinane kakhulu. Zincinane kubo eziphezu emdeni ukubonakala kwi ngemicroscope ukukhanya. ubukhulu kwabo microns-2.

Kodwa uhlobo iiseli iintsholongwane ziyahluka ngokubanzi. Cocci izimvo ibhola bacilli - iinkuni, staphylococci - iidiliya, vibrio - ezahlulwe. gciwane kakhulu bayakwazi intshukumo esebenzayo. Oku kwenziwa ngokusebenzisa misila, yencindi yomlomo okanye igesi vacuoles.

umzimba intsholongwane imelwe iseli enye. Kwelinye icala, le isakhiwo eyahlukileyo isakhiwo esilula kunye zomzimba. Kwelinye - ewuthweleyo imisebenzi yonke eziphilayo. Abancinane gqitha iseli bacteria unako ukutya, ziyazala, ukuhamba, phefumlela nokukhula. Kakade ke, zonke ezi iinkqubo kwenziwa kwinqanaba kwakudala. Kodwa engamelanga ithathwe njenge engxakini.

Ngokwahlukileyo koko, elula iintsholongwane bazenzela izidalwa kunye nqanaba liphezulu lithathelwe. Bona afumaneka imithombo zokupheka, emanzini enomkhenkce, umhlaba, ngaphakathi nangaphandle kwezinye izinto, umoya kunye nendawo engaphandle.

unit ngaphezulu

Ukufana isakhiwo kumphezulu kwefowuni iintsholongwane kunye nezityalo ke ubukho inwebu ezenziwa iseti oluntsonkothileyo iiprothini kunye lipids. Esi sakhiwo lisebenza umsebenzi zokuhamba, mechanical kunye umqobo. Zombini eziphilayo izixhobo phezu iquka udonga iseli. Kodwa yakheke ngemichiza eyahlukileyo kakhulu. Kwizityalo, le nto ndiyibhalayo iselulosi kunye izilwanyana - pectin kunye murein. Bonke carbohydrate ezintsonkothileyo.

Iiseli bacteria omnye unit isakhiwo kumphezulu - capsule uxakaxa equlathe uqhelane kwezinto iiseli organic. Kuyinto enye usikhusele nxamnye umonakalo kunye nokulahlekelwa nokufuma. Enye inkalo yesi sakhiwo kukubonelela asisithintelo ekuqaleni phagocytosis - ukugaywa intracellular ze eziqinileyo.

Iiseli iintsholongwane zahluka plant cells: impendulo

Kukho omnye umahluko esisiseko. iiseli bacteria zahlukile plant cells kuswela ... Impendulo ayimangalisi: izakheko ukugcina ulwazi yemfuza. Kodwa oku kuthetha ukuba iintsholongwane musa nokudlulisela iimpawu ilifa nezizukulwana zabo emva ziiseli musa ukukhangela njengabo.

Enyanisweni oku akuyonyaniso. iiseli bacteria kwahluka kwiiseli izityalo kuphela nokucwangciswa genetic material. Bona musa ezinamaphepha ikhutshwe isiqalo. iimolekyuli DNA babe ubume ring kwaye ibekwe ngqo kwi icytoplasm. Ezi seli zibizwa ngokuba prokaryotic. Izityalo kufuneka inucleus, leyo igcina ulwazi yemfuza, RNA molecule kuhlelwe.

Iiseli zomzimba

iiseli bacteria zahlukile plant cells, ukunqongophala obungcali. Ngamnye kubo eyahlukileyo, ukusebenza njengequmrhu eyahlukileyo. Ngoko ke kule izityalo elinye-elilodwa. Hi xikombiso, le ubulembu Chlorella eluhlaza, kunye Chlamydomonas. Xa izityalo aphezulu wambumba kwithishyu. La maqela leeseli ezifanayo kubume kunye nemisebenzi eziyenzayo. Ngoko ke, zingasebenza ezincinane esinzulu ezikufutshane omnye komnye, ukudala uhlobo umqobo. Inxalenye engundoqo laphu leyo isisiseko umzimba zezityalo ziquka elikhulu, lathamba amalungiselelo.

Ngoko ke, kweli nqaku siza wajonga koko iintsholongwane iiseli zahluka plant cells. Ezona mpawu ziphambili iinkalo izixhobo kunye nesakhiwo umphezulu genetic material.
