Vacuole - kēia ... hana o ka halepaahao vacuoles

I kēia lā, e kamaʻilio pū mākou e pili ana i ka mea i ka vacuole. 'O kēia kekahi ke keʻena o ka halepaahao, oa organelles. Organelles a organelle - ia (particles) e e i na keena, i ka hope, ma ka huli, i ke kumu o ka mea a pau e hoopuni iho la iā mākou.

I mea, ke ao nei mea,ʻaʻole mea ia mea ma mua kilohi. Ka mea, e koho mai i ka microscope, a me ko kakou honua e hoʻololi nui. Ka mua mau makamaka, me keia mea hana nō i loko o ke kula kiʻekiʻe. Kumu e eʻoiaʻiʻo, e haawi aku i ka haʻi'ōlelo ma na rula o ka hoʻohana 'ana i ka microscope i mea e pale aku kaʻawaʻawa loa i hana' ia ma ia he kupaianahaʻoihana. Ma hope o ka manawa pōkole waleʻana aku, e hai aku oe ia mea i ka vacuole. Kēia mea mākou ka papa pukana.

vacuole

E ka hoʻomaka me ka ho'ākāka 'ana pauku. Vacuole - keia organelle (odnomembranny). Ua hiki ke loaʻa i loko o eukaryotic keena. Koke mai i kekahi wahi'ōlelo ho'ākāka aku: na eukaryotes - ka halepaahao i loaʻa kāna mau 'ōlelo. Ka hope ua kaawale mai ka cytoplasm ma ka papaluaʻili lahilahi. Ke kumukuai o ka Kernel mea nui, i ka mea iloko o ka DNA lātoma.

No laila, vacuole - keia organelle hiki ke hoʻokō i na mea he nui kekahi mau hana (o a makou e olelo aku i ka apana uuku na hope). Pehea e mau organelles i hana? Ka mea, originate mai provakuoley, e like me ka mea hōʻike iā mākou i loko o ka palapala o kaʻili lahilahi vesicles.

He nui ka ike a me ka mea e hiki a pau vacuoles māheleʻia i loko o nā pūʻulu:

• digestive;
• pulsating.

I kekahi manawa, pulsating vacuoles kapa contractile. Ka mea, kōkua wehe i ka palaho huahana. He aha hou aʻe i kēia vacuole oihana, mākou e noʻonoʻo hope.

I kanu keena, vacuoles noho oi ma mua o ka hapalua o ka buke, i kekahi manawa ka mea, i loko o merge nui organelle kekahi, a hiki aku i na Ana o ka mea maʻamau.

A pau i ka vacuoleʻili lahilahi ua kaupalena ', ka mea, ua kapaia - tonoplast. Loko, ua hiki ke loaʻa i ka halepaahao SAP. Ka hope oia no ka i kēia eiiiiiaiou:

• ka wai;
• monosaccharides;
• disaccharides;
• tannins;
• carbohydrates;
• nitrates;
• phosphates;
• chlorides;
• ke aloha nāʻakika a me nā waiwai.

oihana

Ano, ua kaumaha i ka līkaia no ke kumu o oihana noʻonoʻoʻia e mākou organelles. Vacuole, a mākou e helu i ka mana hiki ke lawe i ka halepaahao makahiki mai ka 5 a hiki i 90 pakeneka. Ka lanakila ka mea hilinaʻi nui ma luna o kahi keia organelle mea.

Me ka pili ana i na ano o ke keena o ka mea kanu, ua nui hou aku, a me na holoholona i manawa organelles. Mākou i kamaʻilio mua aʻe ia, ke kaumaha ma muli o ka wahi o ka vacuole ke hana likeʻole oihana. Akā, ua hookahi mai ka papa kuhikuhiE poʻeʻelua:

• pili organelles;
• amo kuleana pili i.

kanu aeea

Mākou e neʻe ana i ka nui piha study o organelles i kanu keena. Cell vacuole - keia o kona papa kuhikuhiE ke keʻena. E ka helu ke kumu:

• vacuole absorbs ka wai;
• Ua lawe aku oe i nā palapala 'ona;
• ma kekahi hihia vacuoles paka he nō SAP;
• komo i loko o ke kaʻina hana o splitting na organelles kahiko;
• hoahu i ka mahuaola.

E like me 'oe ke ike, mau kūlana organelles Ua nui maoli. Anei mākou e hōʻike 'ia ka mea, e hiki e uhai iho i ka organelles kahiko, oa hana i ka hana o lysosomes. Nolaila, ke vacuole hiki i na nā'ūhū e pono ai no ka hydrolysis o ke kēia mau waiwai:

• nā polokina;
• momona;
• carbohydrates;
• nukelea nāʻakika;
• phytohormones;
• e yiaeaiiacaaeneiie? iecaianoaaiiuo, a no laila, ma luna o.

Ka mea, i kekahi 'ole i loko o ke kaʻina hana o ka kāʻamaʻai, i mea nui ole wale no kanu akā hoʻi no nā meaola.

zooblast

Vacuoles Hiki ke loaʻa ma:

• freshwater protozoa ;
• multicellular invertebrates.

Ma ka hihia mua mākou e halawai i ka contractile vacuole e lawelawe alii kiaaina. Ia mea, ka mea, e hiki hoi ke Komo 'o ia a me ka hoʻokuʻu' ka liki ole i ka wai. Ka lua o ka pūʻulu, ua hiki ke lawe i na meaola, me:

• ka huahuakai;
• coelenterates;
• ciliated ilo;
• ka pūpū.

Ma kēia mau meaola nāna i hana i ka digestive vacuoles, a i hiki hoi o intracellular digestion. Ka hope hiki ke hanaʻia i loko o na holoholona ma luna, akā, wale i loko o kekahi keena (phagocytes).
