Babban shuka nama: cikakken bayanin

Yadudduka - a tsarin kunshi wani jam'i na kama Kwayoyin wadda da na kowa ayyuka. All kwayar dabbobi da kuma shuke-shuke (ban algae) kunshi daban-daban na nama.

Mene ne masana'anta?

A dabba kyallen takarda kasu kashi hudu iri:

• epithelial.
• tsoka.
• haša.
• m nama.

Dukan su, fãce fa a kan m, ya raba a nuna a cikin jinsin. Saboda haka, epithelium iya zama cubic, lebur, cylindrical, ciliated kuma m. Muscle nama ne zuwa kashi striated, cardiac da santsi. The Group kunshi connective kitse, m fibrous, sako-sako da fiber, reticular, kashi da guringuntsi, jini da kuma Lymph.

Shuka kyallen takarda ne wadannan iri:

• ilimi;
• conductive.
• shafi.
• inji nama.
• excretory (secretory).
• tamkar nama (parenchyma).

Dukan su kasu kashi sub-kungiyoyin. Saboda haka, domin ilimi kyallen takarda ne m, intercalary, gefe da kuma rauni. Conductive kasu kashi da xylem da phloem. Rufe yadudduka hada iri uku: cikin epidermis, abin toshe kwalaba da kuma Cork. Manual ne zuwa kashi collenchyma da sclerenchyma. Secretory nama ne zuwa kashi jinsunan. A babbar shuka nama, kamar dukan sauran mutane, shi ne na dama iri. Bari mu bincika su daki-daki.

Mene ne babban shuka nama?

Akwai hudu na ta jinsunan. Saboda haka, babban masana'anta shi ne:

• aquifer.
• pneumatic.
• assimilation.
• stock up.

Suna da irin wannan tsarin, amma da wasu bambance-bambance daga juna. Babban aiki na wadannan hudu iri nama ne ma ɗan daban-daban.

A tsarin da masana'anta: wani janar Siffar

Ainihin masana'anta na duk hudu jinsunan da aka yi sama da rai Kwayoyin tare da bakin ciki ganuwar. Yadudduka da irin wannan suna don haka ya kira domin su ne tushen duk muhimmanci gabobin. Yanzu bari mu dubi cikin ayyuka da kuma tsarin da asali masana'anta na kowane irin daidaiku a more daki-daki.

Ruwa-hali nama: sifa da aiki

Babban masana'anta na irin wannan da aka gina da manyan Kwayoyin suna da bakin ciki ganuwar. A vacuoles na sel na mucous nama ƙunshi musamman abu, wanda aka tsara domin riƙe danshi.

Ayyuka aquifer masana'anta ta'allaka ne da cewa shi Stores danshi.

Shin ruwa-hali parenchyma a cikin tushe da kuma ganyen shuke-shuke kamar cacti, agave, Aloe, da kuma sauran, girma a cikin m canjin yanayin. Saboda da manyan yawan irin shuka nama zai iya Stock sama a kan ruwa a yanayin saukan ruwan sama ba zai dade.

Features pneumatic parenchyma

tamkar nama sel da jinsin su ne a nesa daga juna. A tsakanin ne intercellular sarari a wadda iska da aka adana.

The aiki na parenchyma ne cewa shi bayar da Kwayoyin wasu kyallen takarda shuke-shuke da carbon dioxide da oxygen.

Akwai irin wannan nama a cikin jiki mafi yawa a cikin fadama da ruwa shuke-shuke. A ƙasar shi ne rare.

Assimilative parenchyma: sifa da aiki

Ya ƙunshi wani matsakaici-sized bakin ciki-hananna Kwayoyin.

Ciki da cell assimilation nama a cikin manyan lambobi ne chloroplast - da wasu gabbansa da alhakin photosynthesis.

Wadannan wasu gabbansa da biyu membranes. Ciki da chloroplast thylakoids ne - discoid bags na enzymes kunshe ne a cikin su. Suna tattara a tara - grana. Recent juna ta wani lamellar - elongated Tsarin kama da thylakoids. Bugu da ƙari kuma, chloroplast ne sitaci inclusions ribosome zama dole don kira na gina jiki, DNA da RNA shafin.

A tsari na photosynthesis - samar da kwayoyin abubuwa daga inorganic da enzymes da kuma hasken rana - ya auku a thylakoids. Babban enzyme wanda ya samar da wadannan sinadaran halayen da aka kira chlorophyll. Wannan abu ne kore (gode masa da ganye da kuma mai tushe na shuke-shuke da wannan launi).

Saboda haka, babban aiki na da irin wannan nama - photosynthesis aka ambata a sama, kazalika da gas musayar.

Assimilation nama ne mafi cigaban a cikin ganye da kuma na sama mai tushe na herbaceous shuke-shuke. shi ne kuma ba a cikin 'ya'yan kore. Assimilation nama ne ba a farfajiya na ganye da kuma mai tushe, da kuma wani m m fata.

Features ajiya parenchyma

Kwayoyin na wannan nama ne halin a matsayin matsakaici size. Su ganuwar ne yawanci bakin ciki, amma za a iya thickened.

Aiki ajiya parenchyma - ajiya na gina jiki. Kamar yadda irin wannan, a mafi yawan lokuta, shi hidima a matsayin sitaci, inulin, da sauran carbohydrates, da kuma wani lokacin - sunadarai, amino acid da kuma fats.

Yana da masana'anta na da irin wannan a cikin tãyuna na tsaba na shekara-shekara shuke-shuke, kamar yadda da kyau kamar yadda a cikin endosperm. A perennial ganye, shrubs, furanni da itatuwa suna kara haja masana'anta na iya zama a cikin kwararan fitila, tubers, Tushen, kazalika a cikin zuciyar na kara.

ƙarshe

Babban masana'anta - mafi muhimmanci a cikin jiki da shuka, tun da shi ne tushen dukkan gabobin. Yadudduka da irin wannan bayar da duk m tafiyar matakai, ciki har da photosynthesis da kuma iskar gas musayar. Har ila yau, ainihin nama alhakin samar da kaya na Organic abubuwa (mafi m ne sitaci) a cikin shuke-shuke da kansu, amma kuma a cikin su tsaba. Bugu da ƙari kuma gina jiki gudanar da mahadi a cikin parenchyma za a iya mallakan iska da kuma ruwa. Pneumatic da ruwa-qazanta tsokoki da ba duk shuke-shuke. A farko ba kawai a hamada, da kuma na biyu - a wetland jinsunan.
