Ib qho organelle (xav tias nws yog ib lub cell sab hauv lub cev) yog ib daim nyias nyias uas muaj nyob rau hauv ib tug cell . Ib yam li hlwb muaj daim nyias nyias los tuav txhua yam hauv, cov kab mob me me no tseem raug khi rau hauv ob txheej ntawm phospholipids kom insulate lawv cov khoom me me hauv qhov loj. hlwb.
Ntawm no, dab tsi yog cov organelles?
Organelles yog cov qauv hauv ib lub cell uas ua haujlwm tshwj xeeb xws li tswj kev loj hlob ntawm tes thiab tsim lub zog. Piv txwv ntawm organelles pom nyob rau hauv eukaryotic hlwb muaj xws li: endoplasmic reticulum (zoo thiab ntxhib ER), Golgi complex, lysosomes, mitochondria, peroxisomes, thiab ribosomes.
Qhov thib ob, dab tsi yog cov piv txwv ntawm organelles? Piv txwv ntawm tsis yog - membrane khi organelles yog ribosomes, cell phab ntsa, thiab cytoskeleton.
Ua kom pom qhov no, dab tsi yog tus yam ntxwv ntawm cov cell membranes?
Cov cell membrane yog semi-permeable, piv txwv li, nws tso cai rau qee yam khoom hla dhau nws thiab tsis pub lwm tus. Nws yog nyias, yoog raws thiab ua neej nyob daim nyias nyias , uas muaj lipid bilayer nrog embedded proteins / The cell membrane muaj cov ntsiab lus loj ntawm cov protein, feem ntau nyob ib ncig ntawm 50% ntawm daim nyias nyias ntim.
Dab tsi yog qhov tseem ceeb tshaj plaws organelle?
Lub nucleus yog qhov tseem ceeb tshaj plaws hauv lub cev cell . Nws muaj cov khoom siv noob caj noob ces, DNA, uas yog lub luag haujlwm rau kev tswj hwm thiab coj txhua yam kev ua ub no cell . Tag nrho cov RNAs xav tau rau cov cell yog synthesized nyob rau hauv lub nucleus.

Dab tsi yog qhov txawv ntawm Marine West Coast huab cua thiab dab tsi yog lub luag haujlwm rau cov yam ntxwv ntawd?
Cov ntsiab lus ntawm Marine West Coast Qhov kev nyab xeeb ntawm cov yam ntxwv tseem ceeb yog lub caij ntuj sov me me thiab lub caij ntuj no thiab cov nag lossis daus txhua xyoo. Qhov ecosystem no muaj kev cuam tshuam loj heev los ntawm nws qhov ze rau ntawm ntug dej hiav txwv thiab roob. Nws yog qee zaum hu ua huab cua sab hnub poob ntug dej hiav txwv lossis dej hiav txwv huab cua
Cov yam ntxwv ntawm cov ntaub ntawv twg yog qhov ntsuas ntawm tus nqi uas cov ntaub ntawv muaj nuj nqis heev?
Variation: Ib qho kev ntsuas ntawm tus nqi uas cov ntaub ntawv muaj nuj nqis sib txawv. ? Kev faib tawm: Cov xwm txheej lossis cov duab ntawm kev sib kis ntawm cov ntaub ntawv hla ntau qhov tseem ceeb (xws li tswb-puab). ? Outliers: Cov qauv piv txwv uas nyob deb heev ntawm feem ntau ntawm lwm cov qauv nqi
Qhov twg ntawm cov no yog tus yam ntxwv ntawm txhua yam muaj sia?
Cov yam ntxwv no yog lub koom haum ntawm tes, kev yug me nyuam, metabolism, homeostasis, heredity, teb rau stimuli, kev loj hlob thiab kev loj hlob, thiab adaptation los ntawm evolution. Qee yam, xws li tus kab mob, pom tsuas yog qee yam ntawm cov yam ntxwv no thiab yog li ntawd, tsis muaj sia nyob
Dab tsi ntawm lub cev nta yog cov yam ntxwv ntawm cov ntug dej hiav txwv ntawm Texas?
Texas 'Gulf Coastal Plains yog sab hnub poob txuas ntxiv ntawm ntug hiav txwv tiaj tiaj txuas los ntawm Dej Hiav Txwv Atlantic mus dhau Rio Grande. Nws cov yam ntxwv dov mus rau toj roob hauv pes npog nrog kev loj hlob hnyav ntawm ntoo thuv thiab tawv ntoo txuas mus rau East Texas
Peb lub neej yog dab tsi thiab lawv cov yam ntxwv tshwj xeeb yog dab tsi?
Peb lub npe suav nrog: Archaea - cov npe qub tshaj plaws, cov kab mob qub. Cov kab mob - tag nrho lwm cov kab mob uas tsis suav nrog hauv Archaea domain. Eukarya - tag nrho cov kab mob uas muaj eukaryotic los yog muaj cov kab mob sib txuas thiab cov nuclei
