He aha ka mitosis a me ka kaʻina i wahi ma ka prophase o ka mitosis?

He aha ka mitosis a me ka meiosis a a pae ka mea, i? Kēia aeea mahele, a i kekahi oko ao. I ka meiosis eha hui ma lalo i hana mai i ka makua nucleus ma i ka hoemi helu o chromosomes (palua). Ma mitosis, no hoi ia lŘlŘ ke kelepona hele mahele, akā, elua wale kaikamahine aeee i kēia 'ano e hana ai me ka ia chromosomes me na makua.

Pela ka mea i ka mitosis a me ka meiosis? Kēia māhele o liluwelo ke kaʻina hana, oiai i na keena i hanaʻia me ka kekahi chromosomes. Nā'ōlelo ma ka mitosis ia lŘlŘ ma multicellular meaola, luna 'ola ana meaola.

ke kahua me

Mitosis i wahi i loko o nā kahua o ka hoʻonaʻauao.

1. A pāpālua hoʻi i ka 'ike ma ka aaiaoe kiʻekiʻe. Here makuahine aeee i pohā ma waena o ka aaiaoe ike. Ma keia kahua, e hoʻololi i ka chromosomes.
2. Mitotic ke kahua. Ua ninoieo o ka manawa paha.

Cell ho okumu ia lŘlŘ i loko o kekahi mau kahua o ka hoʻonaʻauao.

pae

Mitosis ua maheleia i loko o kekahi mau kūlana:

• telophase;
• anaphase;
• metaphase;
• prophase.

Mau kūlana hana ana i loko o ka kekahi kaʻina, a i kā lākou mau 'ano.

Ma kekahi luna 'nunui-ke kelepona hele mitosis pinepine komo ai aeea mahele o ka undifferentiated type. At mitosis ka makua aeea i hookaawale i ke keiki, IeAUPIIe, IAa IO elua o ia mau mea. Kekahi o ia i ka anei, a mau ka mahele, a me ka lua o ka hooki ana.

interphase

Interphase - He aeea hoʻomākaukau no ka hookaawale ana. Nō kāu, keia anu u puka mai a hiki i ka iwakalua o ka hola. I keia manawa, e kahe ana o ka hailona a okoa keʻano o ka hanaʻana, i ka wā a ke keena i hoʻomākaukau ai i ka mitosis.

I loko o kēia wā, he mea ka mahele o nā polokina, organelles huina piʻina ma ka DNA 'ole. Ma ka pau ana o ka papa o aaiaoe nā lātoma i maalahi loa, a ua ole hoʻololi i ka helu ana o chromosomes. 'ālike DNA i spliced a mau chromatids i loko o hoʻokahi lātoma. Hana chromatids i'ālike, aʻo ke kaikuwahine.

Ma hope o ka pau ana o ka interphase o mitosis huli no nae. Ua ninoieo o prophase, metaphase, anaphase a me ka telophase.

prophase

Ka mua pae o ka mitosis - prophase ia. Ua mau no ka hora. Ua Ua conventionally puunaueia i loko o kekahi mau kahua o ka hoʻonaʻauao. Ma ka loiloi mua kahua ma ka prophase o mitosis nucleolus ua mahuahua, e like me ka hopena o ka a na nā lātoma i hana. Ma ka pau ana o ka pae, kēlā chromosome ua haku o nā chromatids kāinoa mua. Nucleoli a nukeleaʻili lahilahi i mea hoʻoheheʻe, na kumu mua a pau i loko o ka hīnaʻi manu i loko o kaʻai. Eia, ma ka prophase o mitosis ua hana achromatin mahele hapa nā huakaʻi hele ma ka halepaahao a pau, a me kekahi mea i pili i ka Central hehee wale. Ma kēia kaʻina hana, i ka maʻiʻo o ka aaiaoe kivila koe ua hoʻololiʻia.

I ka helu ana o chromosomes i loko o ka prophase o mitosis, aole ia e loli ana. He aha ka hana no hoi ia? Ma ka prophase o mitosis ia lŘlŘ disintegration o ka nukelea wahī, i kūpono i kaʻoni iho chromosomes hou i loko o ka cytoplasm. (Particles) o nukelea wahī disintegrated hana liʻiliʻiʻili lahilahi vesicles.

Ma ka prophase o mitosis, i kēia 'ia lŘlŘ: ka holoholona aeea lilo puni, akā, ka mea,' aʻole e hoʻololi i ke kinona o ka mea kanu.

metaphase

Ma hope o prophase metaphase huli no. Ma keia pae, chromosomes kona piko helix ihoiho. Hoopokole chromosomes hoʻomaka e neʻe i ka waenakonu o ka halepaahao. Iloko o ka neʻe aku, ka mea, i kau like ma luna o nāʻaoʻaoʻelua. Aia ka hoʻonoho papa iā metaphase una honua. I ka noonoo pono i ka aeee i maopopo hiki chromosome. He ma metaphase ka mea, e oluolu e hoʻomaulia.

Ma hope iho o ke kahua o ka metaphase chromosomes i ke kālailai, i ho'ākāka 'ia ma ka halepaahao type. Kēia ia lŘlŘ ma ka paleʻana i nā chromosomes ka hoʻohana alkaloids.

Kela a me keia meaola i kona huapalapala iho o chromosomes. No ka laʻana, kā lākou 20 palaoa a me strawberries ma ka mahinaai - 56. I ka kanaka kino chromosomes emi ma mua o nā hua, a pau 46.

anaphase

All keʻano o ka hanaʻana i loko o ka prophase o mitosis na welau a huli no anaphase. I loko o kēia kaʻina hana, e uhaʻiʻia nā pilina paha a pau chromosome, a hoʻomaka i ka hoʻoneʻe i alo aoao elua o kekahi i kekahi. Ma nā anaphase chromosomes e kuokoa. kiʻi ka mea, i loko o keʻano o ke keena.

Pae diverging welau i kaʻauamo chromatids keena. Nō hoʻi 'aneʻi o ka puunaue ana o aaiaoe' ike ma waena o nā nāʻaha hui iho, a me ka makua aeea.

telophase

Chromosomes i aia ma na auamo. Ma lalo o ka microscope, ka mea, e hiki ole i ka ike, no ka mea kāna mau 'ōlelo iwi ua i hanaʻia a puni ia. Kālī ua pau luku.

I mea kanu, heʻili lahilahi ua hana ia ma ka waena konu o ka halepaahao, a hohola ke kiʻekiʻe i na auamo. ʻo ia o ka makuwahine aeea i hookaawale ai i loko o nā māhele. Once kaʻili lahilahi ua maopopo ulu, he mea he kelulose pā pōhaku.

hiʻona mitosis

Cell mahele e hiki nā nā paleki aie i ka kiʻekiʻe mahana, waiū i toxins, pāhawewe. Iloko o ka like ana o mitotic aeee i loko o nā multicellular meaola hiki ke hoʻohana 'hoomake iho no hoi i inhibit mitosis ma ka metaphase ke kahua. Ua apono 'He piha ao o chromosomes, e lawe aku kariotopirovanie.

Mitosis ma Table

E noonoo i na kūlana o ka halepaahao mahele i loko o ka papaʻaina ma lalo nei.

i hiki ke ike i ke kaʻina hana o ka mitosis kapuwaʻi i loko o ka papaʻaina.

Mitosis i ka holoholona a me nā mea kanu

hiki ke ho'ākāka 'ia ma nā hiʻona o kēia kaʻina hana i loko o ka me nā papa.

No laila, ua noʻonoʻo i ke kaʻina hana o ka halepaahao mahele i ka holoholona meaola a me nā mea kanu, e like me kā lākou mau 'ano a me ka oko ao.
