Tus German biologist Theodor Schwann (1810-1882) yog suav tias yog tus tsim ntawm lub cell txoj kev xav . Nws kuj nrhiav tau pepsin, thawj lub plab zom mov enzyme npaj los ntawm cov ntaub so ntswg tsiaj, thiab sim ua kom tsis txhob muaj kev tshwm sim tshwm sim. Theodor Schwann yug ntawm Neuss ze Düsseldorf thaum Lub Kaum Ob Hlis 7, 1810.

Tom qab ntawd, ib tug kuj yuav nug, thaum twg Theodor Schwann ua nws txoj kev koom tes rau txoj kev xav ntawm tes?

Theodor Schwann (1810-1882) Xyoo 1838, Schwann thiab Matthias Jakob Schleiden (1804-1881) tau tsim " cell txoj kev xav ." Schwann tau mus thiab luam tawm nws Monograph Microscopic Kev Tshawb Fawb Txog Kev Pom Zoo hauv Cov Qauv thiab Kev Loj Hlob ntawm Tsiaj thiab Nroj Tsuag hauv 1839.

Tsis tas li ntawd, leej twg yog tsib tus kws tshawb fawb uas tau pab txhawb txoj kev xav ntawm tes? Kev koom tes rau Cell theory

Zacharias Janssen. 1590 ib.
Robert Hook. 1663-1665 Ib.
Anton Van Leeuwenhoek. 1674-1683: kuv.
Theodor Schwann. 1837-1839: kuv.
Matthias Schleiden. 1839 ib.
Rudolph Virchow. 1855.

Raws li kev sib raug zoo, Schleiden qhov kev pab cuam rau lub xov tooj ntawm tes yog dab tsi?

Ua haujlwm ua tus xibfwb ntawm botany ntawm University of Jena, Schleiden yog ib tug founding txiv ntawm cell txoj kev xav . Nws qhia tau hais tias txoj kev loj hlob ntawm tag nrho cov zaub cov ntaub so ntswg los ntawm kev ua ntawm hlwb . Schleiden hais tias cov qauv thiab morphological nta, tsis yog txheej txheem, muab cov organic lub neej nws tus cwj pwm.

Janssen pab tau li cas rau txoj kev xav ntawm tes?

Hans thiab Zacharias Janssen paub rau inventing lub compound optical microscope. Lawv ua nws nyob rau hauv 1590's. Qhov no pab txhawb rau "Lub Cell Theory "los ntawm kev ua kom yooj yim dua thiab ua tau zoo dua thaum soj ntsuam hlwb . Nws tshaj tawm tias tus cell yog lub hauv paus tsev thaiv ntawm tag nrho cov nroj tsuag teeb meem.

Lub luag haujlwm ntawm CDK yog dab tsi hauv lub cev ua haujlwm ntawm tes tshwj xeeb hauv lub voj voog ntawm tes?

Los ntawm phosphorylation, Cdks teeb liab lub xov tooj ntawm tes uas nws tau npaj kom dhau mus rau theem tom ntej ntawm lub voj voog ntawm tes. Raws li lawv lub npe qhia, Cyclin-Dependent Protein Kinases yog nyob ntawm cyclins, lwm chav kawm ntawm kev tswj hwm cov protein. Cyclins khi rau Cdks, ua kom cov Cdks rau phosphorylate lwm cov molecules

Ob qhov tseem ceeb ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim rau lub cell hauv txhua theem?

Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum lub cell loj hlob thiab replicates nws DNA. Qhov thib ob yog theem mitotic (M-Phase) thaum lub sijhawm cell faib thiab hloov ib daim qauv ntawm nws cov DNA mus rau ob lub hlwb zoo tib yam

Dab tsi ntawm lub xov tooj ntawm tes ua raws li qhov chaw tswj kev ua haujlwm ntawm tes?

Lub nucleus muaj cov ntaub ntawv genetic information (DNA) onspecial strands hu ua chromosomes. Function - Lub nucleus yog 'tswj chaw' ntawm lub xovtooj ntawm tes, rau cellmetabolism thiab kev yug me nyuam. Cov kab mob hauv qab no pom muaj nyob rau hauv cov nroj tsuag thiab tsiaj txhu

Dab tsi yog 2 qhov tseem ceeb ntawm lub voj voog ntawm tes thiab dab tsi tshwm sim rau lub cell hauv txhua theem?

Cov xwm txheej no tuaj yeem muab faib ua ob qhov tseem ceeb: interphase (hauv nruab nrab ntawm kev sib faib theem ua pawg G1 theem, S theem, G2 theem), thaum lub xov tooj ntawm tes tsim thiab ua nrog nws cov haujlwm metabolic; mitotic theem (M mitosis), thaum lub sij hawm lub cell yog replicating nws tus kheej
