Nā mea olaʻokoʻa: He aha ka meaola i prokaryotes?

A meaola i prokaryotes? Prokaryotes - ka mea kupaianaha a me nā mea kolo. Ka mea hiki ke ola i loko o kokoke kekahi kaianoho koholā, e kāinoa a loaa nui ikehu ma naʻano likeʻole, a me kekahi o ia mau mea i ka poe Moana.

Prokaryotes: mau 'ike

A meaola i prokaryotes? Mau mea na meaola loa lehulehu e noho i ka Honua Honua. O kēia Mea Maluna o prokaryotes ka nānā 'ana ma luna o kekahi me ka hui pu ana o genomic a me ka phenotypic ka waiwai. I ka helu o ka ikeia laha 'o prokaryotes manawa aku i 6200. mau meaola iʻikeʻia ma ka Honua ma mua kekahi'ē aʻe, a hoomau i ka maluhia nei i loko o ka manawa.

Mea kūʻiʻo hoihoi, a he manawa pōkole ano o prokaryotes

1) Prokaryotes ola na wahi a pau he mea ola, a me ka mea, mehe mea, ola hiki ole ia, no ka mea, i ke ola o kēia mau meaola hiki e anu, wela,ʻakika a'ākilikai Media,.

2) Ua 'akomi i Prokaryotes a hiki ma ka hohonu o kahi o 3 ei ma lalo o ka honua i ka ili honua.

3) ka nui o nā prokaryotes - heʻano o hookahi-aa? Meaola me ka nui adaptive nona iho.

4) nui kanaka e hoʻoneʻe, ka hola hapalua o nā prokaryotes hiki hoi ke kuhikuhi ana.

5) nā aeee i prokaryotes simpler ma mua o eukaryotic like me ka pā 'ole a me ka genomic hui.

6) ka populations o prokaryotes ulu a me ke hakuloli koke.

7) Under 'ano kūpono kekahi kaukahi aeea mea hiki ke paka i ka nui panalaau ia o ke keiki i loko o ka kŘpa a pōkole manawa.

8) noiʻi mau paʻahau panalāʻau Eia kekahi laʻana ma ka mea e lawe mai i nā lāʻau kū-thaw ho okolohua me ka hoʻomau i ka makaikai i ka hiʻona o kēia hoomanawanui mea.

Food ka hoʻololiʻana

I ka piha noonoo o ka meaola i prokaryotes, ia ninoaaeyao nui i wahi i kekahi kaʻina hana no ka hoʻomākaukau ai. Penei, meaola loaʻa ikehu mai ka malamalama i phototrophic, like me ka hopena o Nine Inch reactions - chemotroph. Meaola i wale kalapona'okikene lua (CO ₂₎ me ke kalapona kahi, e autotrophic. Ola meaola, i pono ma ka liʻiliʻi loa hoʻokahi ke aloha nutrient kumu (monakō koko), e heterotrophs.

Photoautotrophs - photosynthetic meaola i hoʻohana mālamalama ikehu e hoʻoulu i ka hoʻololi kemikala o ke aloha i huiʻia, mai ke kalapona'okikene lua (kanu a me ka līoho). Chemotroph Pono wale i carbon dioxide i loko o ka kalapona kumu, akā, i loaa i ka ikehu e oxidizing 'okanikaʻole waiwai (hydrogen sulfide (H ₂ S), ammonia (NH ₃₎ a me ka hao Ion (Fe ^2+)). Kēia hanana hana o ka ai no prokaryotes.

kaianoho koholā

Me ka pili ana i ke kaiapuni prokaryotes kaianoho koholā, ka mea, e ia i ka loa like. He nui hiʻona o prokaryotes i pili i ka mea e mea hiki ke ola i loko o ka loa loa keia mau meaola: kiʻekiʻe'ōmiko, lōʻihi ka wela, wahi nele ka oxygen. Prokaryotes ke ola i loko o ke kino o nā holoholona a me nā kānaka, kōkua i ka mea nona ma symbiosis e hana i kaʻoihana o kona kino (digestion).

Power prokaryotes ua hua mai la ia mai kaʻano o nā kumu. Kēia paha e ka huli o ka make keena a holoholona no ola (loa pohihihi). Ka loa e like me ka hana o ka loaa ana i ka mea e pono ai māhuaola - mea e ho okumu i ikehu ma kāʻamaʻai, a me ka hoʻohana 'ana i nā nā minelala hao e like me ka luaipele.

Ano a me ka 'ole o ka prokaryotes

A meaola i prokaryotes? Aia i mau papa kuhikuhiE ano: koʻohune a me hookahi-aa? Meaola. Prokaryotic keena nā wai kokoʻili lahilahi, cytoplasm, ribosomes a aaiaoe mea (DNA ole RNA). Kekahi? Ueo pū i nā hale a - ke kelepona hele pa, flagella a me na mea e ae. Ka 'ole o ka prokaryotic keena, hula kēlā me kēia halepaahao hale a me eiiiiiaiou heʻano nui kūlana i loko o ka ulu, ola a me nā'ōlelo.

wai kokoʻili lahilahi

Prokaryotic aeee hiki i ka nunui-ahu wai kokoʻili lahilahi. Ma prokaryotes,ʻikeʻia me gram-io koʻohune, no kekahi laʻana, pinepine mau wai kokoʻili lahilahi, ma waena o i mea no ka ai-kapaia periplasm. Like i loko o nā mea a pau keena, i ka wai kokoʻili lahilahi i loko o prokaryotic aeee mea kuleana no ka hooponopono a me ka hooponopono ana o nā mea a pau i mea he hapa o ka halepaahao.

Palapala i wahi ma kaʻili lahilahi, me hoʻouna 'a me ka loaa mau lepa a mai nā Nine Inch a me ka mea koʻohune hana kūleʻa me eukaryotic keena, meaola i infectious keʻano o ka hanaʻana. It E e kaʻikaʻiʻia ma ka manaʻo i ka wai kokoʻili lahilahi mea paʻa no nā prokaryotic a me ka eukaryotic keena.

cytoplasm

Cytoplasmic ma prokaryotic keena, reminiscent o ka jelly a tuko pīlali, he kinowai waiwai, i na hale a pau'ē aʻe ke kelepona hele eiiiiiaiou. Nei, i ike ai biologists i prokaryotic keena o ka luna 'a me ka iaea ooieoeiiaeuiiai cytoskeleton, like i ka mea i eukaryotic keena. Penei, o ka halepaahao ke kōkua ma muli o kona helehelena.

ribosomes

Prokaryotic ribosomes mea uuku, a i ka iki okoa shape a me ka haku mele 'ana ma mua o ka poʻe i loaʻa i loko o eukaryotic keena. He'ālike, a me ka hana ana o keia ke kelepona hele ke keʻena - kūkuluʻia a me ka hōʻikeʻana nā polokina e hoʻouna DNA.

aaiaoe mea

All aeee mea prokaryotes iloko he nui nui o aaiaoe mea i loko o ka palapala o ka DNA a me ka RNA. No ka prokaryotes nā meaola kona keena i nuclei, hookahi nui hoʻopoepoe DNA hapa i loaʻa i ka hapanui o na nā'ōewe e pono no ka ka ulu, ola a me nā'ōlelo o ke keena. DNA i loko o kēia mau keena ua hōʻike ma kaulele kaʻina.

Nō kāu, o ka DNA hiki ma ka halepaahao i mea e e decoded a ua hoohuliia mai i loko o RNA. Ke microscope ke ike i ka wepa i loko o ka ua pahu, ka mea, o ka aaiaoe mea (DNA). Ma waho aʻeo ia i ka nui loa hookahi o ka chromosomal DNA o na mea he nui prokaryotic aeee i pihaʻi me'āpana liʻiliʻi o ka DNA kapa plasmids. Mau hoʻopoepoe DNA apo i mānewanewa ka nānā 'ana o chromosomes, a hiki e hoolilo mai i ka prokaryotic aeea i kekahi.

Ma muli o ia kona 'ano o nā prokaryotes hiki maluhia ola i loko o kekahi' ia, ka mea, i na wahi a pau - i loko o ka mau papa, a me ka paakai o ic ??, hoki, lua pele a me craters i loko o ka hohonu i loko o ka'ōpū o ka Honua. Penei, prokaryotes i ka loa a me ka paakiki viable meaola ma luna o ka Honua.
