A lichen Nws yog ib qho kev sib xyaw ua ke ntawm ob kab mob, ntsuab alga lossis cyanobacterium thiab ascomycete kab mob , nyob rau hauv kev sib raug zoo symbiotic. Upper cortex ntawm fungal hyphae muab kev tiv thaiv. Photosynthesis tshwm sim hauv thaj tsam algal. Lub medulla muaj fungal hyphae.
Tsis tas li ntawd, lub luag haujlwm ntawm fungus nyob rau hauv lichen yog dab tsi?
Keeb Kwm teb: Dab tsi yog luag hauj lwm ntawm algae thiab fungi hauv lichen ? Cov fungi absorbs dej thiab minerals thiab muab lawv rau algae. Cov algae npaj zaub mov nrog lawv nrog kev pab ntawm chlorophyll. Cov zaub mov npaj tau muab faib rau fungi Raws li, nws yog heterotrophic.
Qhov thib ob, yog vim li cas lub qaum cortex ntawm lichen yuav pob tshab thaum hydrated? Thaum qhuav, lichens tsuas yog noj cov xim ntawm mycobiont (cov fungus) nws tus kheej los yog ua tau ua dab thiab grey. Tab sis thaum ntub, lawv yog hloov tag nrho. Qhov no yog vim cov kab mob fungal hauv lub sab sauv cortex ua pob tshab thiab cov xim ntawm algal lossis cyanobacterial txheej ua tau ci dhau.
Tsis tas li ntawd kom paub, cov txiaj ntsig dab tsi ua rau fungi hauv lichens tau txais los ntawm lawv cov neeg koom tes?
Txheej txheem cej luam ntawm lichens Nyob rau hauv rov qab, lub fungal khub cov txiaj ntsig cov algae lossis cyanobacteria los ntawm kev tiv thaiv lawv los ntawm ib puag ncig los ntawm nws filaments, uas tseem khaws cov dej noo thiab cov as-ham los ntawm ib puag ncig, thiab (feem ntau) muab cov thauj tog rau nkoj rau nws.
Phycobiont muaj nuj nqi hauv lichens yog dab tsi?
a) Lub phycobiont ib feem ntawm lichen yog autotrophic ib feem uas yog algae. Lub luag haujlwm ntawm autotrophic algae yog muab khoom noj khoom haus. Nws synthesizes organic zaub mov los ntawm cov txheej txheem ntawm photosynthesis.

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
Lub luag haujlwm ntawm carbon nyob rau hauv molecular ntau haiv neeg ntawm lub neej yog dab tsi?
Cov pa roj carbon monoxide yog qhov tsis sib xws hauv nws lub peev xwm los tsim cov loj, complex, thiab ntau hom molecules. Cov proteins, DNA, carbohydrates, thiab lwm yam molecules uas paub qhov txawv ntawm cov khoom muaj sia los ntawm cov khoom siv tsis muaj sia yog txhua tus muaj cov pa roj carbon atoms sib txuas rau ib leeg thiab rau cov atoms ntawm lwm cov khoom
Lub luag haujlwm ntawm Photobiont hauv lichen yog dab tsi?
Lub luag hauj lwm ntawm photobiont hauv lichens yog qhov tseeb - muab cov pa roj carbon nyob rau hauv daim ntawv ntawm cov suab thaj yooj yim. Cov suab thaj no yog siv los ntawm cov fungi kom tswj lub cev muaj zog, loj hlob, thiab yug me nyuam
Lub organelle twg yog lub luag haujlwm rau lub zog tshuaj uas xav tau rau lub cell ua haujlwm?
Mitochondria Function Mitochondria feem ntau hu ua "powerhouses" lossis "zog factories" ntawm lub xovtooj vim tias lawv yog lub luag haujlwm rau kev ua adenosine triphosphate (ATP), lub xovtooj ntawm lub zog nqa lub cev
Cov txheej txheem dab tsi yog lub luag haujlwm rau txoj haujlwm ua haujlwm sib txawv?
Position-effect variegation (PEV) tshwm sim thaum cov noob ib txwm nyob hauv euchromatin yog sib xyaw nrog heterochromatin los ntawm kev hloov kho lossis hloov pauv. Thaum lub ntim ntim heterochromatin kis thoob plaws heterochromatin / euchromatin ciam teb, nws ua rau kev hloov pauv ntawm kev ntsiag to hauv tus qauv stochastic
