Infusorian trumpeter: qauv, tu tub tu kiv, cov nqi ntawm cov xwm

Tag nrho Internet yog lawm ua tus sau nrog khoom hais txog cov ciliate-nkawm khau. Thaum ntaub ntawv hais txog lub trumpeter txom nyem heev, mus nyeem lawv tsis feem ntau muaj lub sij hawm, tsis suav qhov tseeb hais tias nws yog ib qho ntawm feem ntau cov neeg uas nyob pas dej. Infusorian trumpeter tej zaum yuam kev suvoek los yog rotifers. Dab neeg paub neeg tsis zoo li zoo li qhov tseeb, ob peb yuav ntseeg hais tias muaj nyob rau hauv lub ntiaj teb no xws zoo protozoa.

Keeb kwm ntawm lub npe

Lub npe ntawm lub ciliates hais lus rau nws tus kheej. Nws los ntawm nws qhov tsos. Tus duab ntawm nws lub cev ciliate Stentor tsa ib tug gramophone trumpet los yog kub. Nws muaj zoo sib xws nrog ib tug ntseeg nkaws expanding soj caum, uas nyob rau hauv lub kawg mus txog rau lub nplos li zoo li ib tug cua ntsuas. Txawm li cas los, xws infusoria tsuas yog thaum twj ywm. Yog hais tias nws yog ntxhov, nws yog, ua tsaug rau nws cov nqaij fibers, thaum nws ua zoo li ib tug zais pa.

Tej me nyuam dej ciliate-cav tshuab yog ib tsev neeg ntawm "Lub cav tshuab", uas yog lub genus Stentor (Blower). Lub npe Stentor pom nyob rau hauv ancient Greek myths xwb. Nws yog ib lub tim, nrog ib tug muaj zog lub suab, nws twb siv rau cov ntawv tshaj tawm ntawm tus huab tais txoj kev sib.

Stentor: ib nyuag lus piav qhia txog

Luv luv muab, dab tsi Stentor, nws yog floating thiab sessile ciliates. Ciliate-blower (nyuag piav qhia): cov sab ib feem yog reducible elongated kav uas muaj lub peev xwm mus rau Mount infusorian tej yam khoom uas yog nyob rau hauv cov dej. Qhov kev ua yuav siv sij hawm qhov chaw nrog rau cov kev pab los ntawm cov kua nplaum secreted Stentor.

Foreseeing qhov kev nyab xeeb soj caum trumpet neeg uas ua ntawv nrog rau cov kev ceev pib kom txo tau, lub sij hawm no nws lub cev yog compressed. Yuav kom txuag nws txoj sia infusorian blower yuav txo tau rau ib tug ob peb zauv feem ntawm ib tug thib ob mus rau ib tug thib peb ntawm qhov ntev! Nyob rau hauv lub pib txoj hauj lwm, nws rov maj mam lub sij hawm no muaj 10 vib nas this. Yuav txo tau kev txhawb los ntawm lub muaj nyob rau hauv lub cell ntawm nqaij fibers.

Nyob rau hauv tas li ntawd, nws muaj ib tug zoo kawg li muaj peev xwm rau kev nyab xeeb. Infusorian trumpeter muaj nyob rau hauv koj lub cev suav tsis tau qhov me me nyob rau hauv uas lub rods muab zais nrog dub lub tswv yim, uas muaj tshuaj lom. Cov, ntaus xws riam phom tuag tes tuag taw tam sim ntawd, nyob rau hauv lub phem tshaj cov ntaub ntawv, nws tuag.

Infusorian kis thaum muaj kev kub ceev. Cov kev tshab txhais yog lub simplicity thiab yooj yim ntawm tsiv nws sib npaug hlwv poob Waterfowl, kab, thiab lwm yam uas muaj sia nyob. Hlwv yog tsim ntawm ib tug kub hauv qab no 0 degrees C.

tsos

Stentor lub cev muaj ib tug yam ntxwv funnel-zoo li tus daim ntawv no, nws pem hauv ntej kawg tsam nyob rau hauv ib tug funnel. Nws yog peristomalnoe teb nyob rau txheej ntug uas hauj lwm ua ke lawv ntev cilia membranelly daim ntawv nyob ib ncig ntawm lub qhov ncauj kab noj hniav.

Melenkie cilia nyob rau hauv daim nyias nyias yuav tsum vov lub longitudinal kab ntawm lub tag nrho lub cev ciliates. Muaj hom uas nws lub cev yog nws tsuas lub xam qhovkev xim: trumpet xiav los yog kob xiav thiab ntsuab trumpet.

Lub ciliates yog loj los ntawm 1.2 hli mus rau 3 lub hli. Lawv zoo li tej zaum yuav raws li nram no:

• Mobile.
• Rooj zaum.
• Colonial.
• Tib.
• Hloov tus duab ntawm lub hlwb.
• Tsis txhob hloov tus duab ntawm lub hlwb.

Nyob rau sab saum toj ntawm lub cell them endoplasm muaj siderogenous saib, thiab heev tuab plhaub.

Infusorian trumpeter: systematics

Yog hais tias peb xav txog qhov trumpeters nyob rau hauv cov nqe lus ntawm taxonomy, cov no yog cov nyuaj nyob rau hauv lub chav tsev raznoresnichnyh ciliates. Raws li nrog rau ze cov txheeb ze, nyob rau lawv lub cev cilia yog ob ntau hom kev - luv luv thiab ntev.

Luv cilia, uas yog meant rau da dej, Stentor lub cev yog them tusyees. Ntev plaub muag yog nyob ze ntawm lub qhov ncauj, adhering zoo rau ib leeg. Lawv pab kom ncaj rau dej rau cov qhib lub qhov ncauj. Tsis muaj qhov txawv nruab nrab ntawm lawv yog tsis tau pom, tsuas yog nyob rau hauv ntev, cov qauv ntawm cov tib.

khoom noj khoom haus

Qhov yooj yim cov yam ntxwv ntawm tag nrho lub neej zog, xws li khoom noj khoom haus. Cov tib pub thiab yuav ua li cas lub plab zom mov ntawm Stentor - ib tug heev interesting lo lus nug. Infusorian trumpeter considers nws cov ntsiab khoom noj khoom haus cov kab mob. Nrog rau cov siav khoom tseem me me protozoa, algae plankton thiab lwm tus nyob rau hauv cov dej. Feem ntau, trumpeters, ua txhaum cov kev cai ntawm mechanics, ncua ua luam dej rau pem hauv ntej thaum xaus ntawm lub cev. Qhov no slow suab yuav pab kom lawv mus ntse ntes tus npaj prey. Fine zaub mov nkag mus rau ntawm lub qhov ncauj ntxiv mus rau hauv trubkovidnuyu caj pas. Residues tom qab plab zom mov cuag outwardly los ntawm poroshitsu.

Ciliates yog ib tug voracious zeej, nws yeej ib txwm qhib nws lub qhov ncauj, nws yog lossi powered. Tsuas yog thaum lub sij hawm yug me nyuam rau lub caij, txoj kev no yog haujlwm. Feem ntau ntawm lawv pom tau hais tias ua npua.

txoj kev ntawm lub neej

Lub ntsiab ntxawg chaw zov me nyuam yog cov tub ntxhais Stentor. Lawv yog tsim los xyuas kom meej tias tag nrho cov dab nyob rau hauv lub cell yuav npaj mus kom zoo thiab ceev nrooj ua txhaum. Ciliate blower muaj ib tug ceeb muaj peev xwm mus coj lub cev mus rau tus thawj daim ntawv tom qab raug mob. Txawm tias thaum twg nws txiav mus rau hauv ob peb qhov chaw, lawv txhua tus tom qab ib tug thaum puv mus rau hauv ib tug me me Stentor, ces, noj mov sai heev, acquires nws cov thawj loj.

Qhov tshaj plaws xwb koj yuav tsum tau ua - yog muaj nyob rau hauv lub so ntawm macronucleus. Thaum mus coj ib tug dej los ntawm lub pas dej nrog poob nplooj thiab tso nws nyob rau hauv lub tshuab kuaj kab mob, koj muaj lub sij hawm mus soj ntsuam cov neej ntawm cov tub hluas no cov neeg sawv cev ntawm lub ntiaj teb no ntawm me me tsiaj, uas yog heev nthuav.

Stentor: internal qauv

Nyob rau hauv Stentor muaj ib contractile vacuole. Nws muaj ib tug tank thiab lub resulting raws. Ib tug yam ntxwv feature ntawm uas yog tus qauv ntawm ciliates - yog ib tug loj cov tub ntxhais macronucleus. Tom ntej no mus nws, muaj ntau ntau me me micronuclei.

Peb kuj muaj ib tug trumpeter thiab ib tug me me ntxhais, tej zaum yuav muaj ob peb. Tus qauv ntawm ciliates xws li tawm digestive vacuole, cilia, muaju, qhov ncauj, digestive vacuole, tshem tawm cov zaub mov qhov chaw (poroshitsa), keeb thiab nucleolus, lub contractile vacuole.

Ciliates Trumpeter: tu tub tu kiv

Stentor yam ntxwv asexual tu tub tu kiv. Nws yog nqa tawm los ntawm transverse division ntau fission los yog budding rau hauv ob, uas yuav tshwm sim nyob rau hauv svobodnopodvizhnom mob.

Thaum asexual tu tub tu kiv yog tus faib ntawm tag nrho cov nuclei, cov txheej txheem ntawm cov trumpeter rov ob los yog peb lub sij hawm ib lub lim tiam ntawm txawv Team sib. Tus nqi ntawm no hom ntawm tu tub tu kiv yog nyob rau txawv yog vim li cas, nws yog, ua ntej ntawm tag nrho cov, cov ib puag ncig tej yam kev mob: kub, nyiaj ntawm cov zaub mov, thiab lwm yam

Micronucleus division tshwm sim mitonicheski. Macronucleus Ameslikas muab faib thiab yus los ntawm ib tug doubling ntawm DNA. Thaum faib lub ciliates yuav tau soj ntsuam qee cytoplasmic organelles. Feem ntau, lawv yog affiliated cov neeg uas tau rov tsim tshiab cov plaub muag thiab lub qhov ncauj qhib.

Ciliate pib kwm los nyob noj thiab loj hlob, thiab ces multiplies dua. Zaum tau ua ib tug loj tus naj npawb ntawm thwmsim rau teb cov lus nug, yuav ua li cas ntev yuav cov tsiaj me nyuam asexually.

Sim kawm pom tau hais tias nyob rau hauv ib tug ob peb tiam nyob rau hauv lub neej voj voog ntawm ciliates yuav tsum sib deev tu tub tu kiv los yog conjugation txheej txheem, thaum lub sij hawm uas lub ob cov neeg tuaj mus rau hauv kev sib cuag nrog txhua lwm yam plab. Thaum lub hlws ris ntawm lub plhaub yaj mus ua ib lub cytoplasmic choj. Macronucleus pib mus ua txhaum down thiab faib mus rau 4 microcores tub ntxhais. Peb lawv twb tag pov tseg, thiab tus plaub yog lub division nyob rau hauv ib nrab. Cov - lub tsim ntawm txiv neej thiab poj niam nuclei nyob rau hauv txhua ciliates.

Yog li, kev sib deev tu tub tu kiv txheej txheem tsis cuam tshuam rau kev nce rau hauv tus naj npawb ntawm Stentor. Nws tsuas muaj txhawb rau daim ntawv rov ntxiv ntawm raws roj ntsha lub zog thiab lub rov tshwm sim ntawm tshiab ob peb ua ke ntawm kev tshuaj ntsuam genetic ntaub ntawv.

Stentor: tseem ceeb nyob rau hauv cov xwm

Ciliates, zoo li lwm yam yooj yooj yim, ua si lub luag hauj lwm ntawm cov neeg tu mob, dej ntshiab los ntawm cov pa phem los ntawm kev noj teeb meem kab mob thiab lwj organic seem. Los ntawm tus xov tooj ntawm cov tsiaj koj yuav txiav txim seb cov neeg kawm ntawv ntawm dej muaj kuab paug.

Stentor nyob rau hauv cov zaub mov saw yog ib tug ntawm cov thawj Cheebtsam. Yog hais tias uas ua rau kom paaj tej yam kev mob, lawv cov me nyuam heev sai sai, thiab ib tug myriad ntawm cov yooj yim ua ib tug nyiam zaub mov rau cov tub ntxhais ntses, me me crustaceans, kab thiab lawv cov kab reservoirs. Cov yav tas, nyob rau hauv lem, ua zaub mov ntau loj reservoirs tsiaj, thiab nuv ntses Fry.

Tham txog cov amazing creatures infinitely. Infusorian trumpeter, ib tug nqi nyob rau hauv uas qhov xwm ntawm niaj hnub no tseem yog ib tug paub tsis meej, yuam zaum ua hauj lwm rau qhov kev tshawb rau tag nrho cov lus teb hais txog qhov no zeej. Ntau seem yuav tsum tau ua nyob rau hauv thiaj li yuav paub thiab to taub ib tug me ntsis yooj yim.
