Vacuole - wannan ... aiki na cell vacuoles

Yau za mu yi magana game da abin da yake cikin vacuole. Wannan shi ne wani bangaren na cell, watau wasu gabbansa. Wasu gabbansa ko organelle - shi barbashi cewa yin up da Kwayoyin, da karshen, bi da bi, su ne tushen duk abin da na kewaye da mu.

A gaskiya ma, cikin duniya shi ne ba abin da alama da farko kallo. Ya kamata karba a madubin, kuma mu duniya za su canza sosai. A farko ko fahimtar wannan kayan ya faru har yanzu a makarantar sakandare. Malamai kamata a tabbatar an ba da lacca a kan dokoki na amfani da madubin likita domin kauce wa m faru a irin wannan m zama. Bayan wani taƙaitaccen digression in gaya muku cewa shi ne vacuole. Wannan shi ne mu babban batun.

vacuole

Bari mu fara da wani definition sashe. Vacuole - wannan organelle (odnomembranny). Yana za a iya samu a eukaryotic Kwayoyin. Nan da nan gabatar da wani kadan bayani: da eukaryotes - a cell dauke da core. A karshen ne rabu da cytoplasm ta biyu membrane. The darajar da kwaya ne manyan, cewa shi ya ƙunshi cikin jigidar halittar DNA.

Saboda haka vacuole - wannan organelle iya yin da yawa daban-daban ayyuka (na abin da muka ce dan kadan daga baya). Ta yaya wadannan da wasu gabbansa suna kafa? Sun samo asali ne daga provakuoley, kamar yadda suka bayyana a gare mu a cikin nau'i na membrane vesicles.

Yana da muhimmanci a san da kuma abin da za ka iya duk vacuoles kasu kashi biyu kungiyoyin:

• narkewa kamar;
• pulsating.

Wani lokaci pulsating vacuoles kira contractile. Suna taimaka cire lalata kayayyakin. Abin da kuma ya aikata wannan vacuole ayyuka, za mu yi la'akari da daga baya.

A shuka Kwayoyin, vacuoles zauna fiye da rabin žara, wani lokacin da suke ci a cikin daya manyan organelle, wanda yanzu ya wuce da girma daga cikin talakawa.

Duk da vacuole membrane aka iyakance, shi ne ake kira - tonoplast. Ciki ba za mu iya samun tantanin halitta sap. A karshen kunshi wadannan aka gyara:

• ruwa.
• monosaccharides.
• disaccharides.
• tannins.
• carbohydrates.
• nitrates.
• phosphates.
• chlorides.
• Organic acid da kuma sauran abubuwa.

ayyuka

Yanzu muna bayar ware ainihin ayyuka dauke da mu wasu gabbansa. Vacuole, wanda mu yanzu lissafa abubuwan da ayyuka iya dauka da wayar sarari daga 5 zuwa kashi 90 cikin dari. Assigning ya dogara a kan inda wannan organelle ne.

Game da iri Kwayoyin a cikin shuka akwai da yawa more, da kuma dabbobi da lokacin da wasu gabbansa. Mun riga ya bayyana cewa, dangane da wurin da vacuole iya yi daban-daban ayyuka. Amma mun ware fitar biyu main wadanda:

• dangantaka da wasu gabbansa.
• kai aiki.

shuka cell

Mu yanzu, matsa zuwa wani karin cikakken nazari na wasu gabbansa a shuka Kwayoyin. Cell vacuole - wannan shi ne ta babban bangaren. Bari mu lissafa me ya sa:

• vacuole garwaya da ruwa.
• Yana kawar da abubuwa masu cutarwa.
• a wasu lokuta vacuoles zõ da wani Milky sap.
• da hannu a aiwatar da tsagawa da haihuwa da wasu gabbansa.
• adana up gina jiki.

Kamar yadda ka gani, wadannan da wasu gabbansa rawa ne da gaske mai girma. Shin, ba mu ambaci cewa sun sami damar karya saukar da haihuwa da wasu gabbansa, watau yi da aiki na lysosomes. Saboda haka, vacuole iya samun enzymes da ake bukata domin hydrolysis da wadannan abubuwa:

• sunadaran.
• mai;
• carbohydrates.
• nucleic acid.
• phytohormones.
• maras tabbas samar, da sauransu.

Suna kuma da hannu a cikin tsari na photosynthesis, wanda yana da muhimmanci ba kawai ga shuke-shuke, amma har ga sauran kwayoyin.

zooblast

Vacuoles za a iya samu a:

• ruwa tare protozoa .
• kwayar kwaro.

A cikin farko idan za mu sadu da contractile vacuole bauta wa gwamnan. Wannan shi ne, za su iya mamaye da kuma sakewa wuce haddi ruwa. Na biyu kungiyar za mu iya kawo da yawa kwayoyin, ciki har da:

• Sponges.
• coelenterates.
• ciliated tsutsotsi.
• Shellfish.

A cikin wadannan kwayoyin samar da narkewa kamar vacuoles, wanda suke iya kwayuka narkewa. A karshen za a iya kafa a cikin mafi girma da dabbobi, amma kawai a wasu sel (phagocytes).
