Qhov sib txawv tseem ceeb ntawm membranous thiab nonmembranous organelles yog tias cov membranous organelles tsis tuaj nyob rau hauv prokaryotic hlwb thaum nonmembranous organelles muaj nyob rau hauv ob leeg prokaryotic thiab eukaryotic hlwb.
Lub xovtooj ntawm tes yog lub hauv paus ntawm cov kabmob muaj sia. Txawm li cas los xij, muaj ob hom cellular koom haum uas yog prokaryotic thiab eukaryotic. Ib qho ntawm cov yam ntxwv tseem ceeb uas paub qhov txawv ntawm prokaryotes thiab eukaryotes yog qhov muaj thiab tsis muaj daim nyias nyias ntawm cov cell organelles. Cov hlwb prokaryotic tsis muaj cov kab mob sib txuas nrog cov organelles thaum cov hlwb eukaryotic muaj cov kab mob sib txuas. Membrane-bound organelles yog kaw nrog cov plasma membrane zoo li daim nyias nyias thaum nonmembranous organelles tsis nyob nrog cov membranes. Cov kab lus no yog los tham txog qhov sib txawv ntawm membranous thiab nonmembranous organelles.
Membranous Organelles yog dab tsi?
Membrane-bound organelles tsuas muaj nyob hauv cov hlwb eukaryotic xwb. Piv txwv ntawm daim nyias nyias organelles yog cov nucleus, ntxhib endoplasmic reticulum (ER), du endoplasmic reticulum, Golgi apparatus, mitochondria, plastids, vacuoles thiab lysosomes. ER muaj cov ceg tawv uas txuas nrog cov plasma membrane thiab nuclear membrane. Nyob ntawm seb muaj cov ribosomes ntawm daim nyias nyias ntawm cov tubules muaj ob hom ER uas yog du ER (SER) thiab ntxhib ER (RER). RER muaj ribosomes ntawm qhov chaw thaum SER tsis muaj ribosomes ntawm qhov chaw.
Mitochondria yog lub zog ntawm lub hlwb. Lawv muaj nyob rau hauv lub cytoplasm, thiab lawv muaj ntau yam duab. Lawv tej zaum yuav yog spherical, oval, los yog pas nrig-puab. Raws li txoj cai, mitochondrion yog ob daim nyias nyias organelle. Nws muaj ob daim nyias nyias; ib tug du txheej membrane thiab ib tug puab membrane. Yuav kom nce qhov chaw ntawm lub puab membrane, nws tsim cristae. Cristae dais ntau oxysomes.
Daim duab 01: Mitochondrion
Ntxiv mus, Golgi apparatus yog ib daim nyias nyias-bound organelle. Vesicles yog cais los ntawm cytoplasm los ntawm ib chav tsev membrane. Chloroplast yog ob lub membranous organelles, nyob rau hauv uas, ob qho tib si daim nyias nyias yog du. Cilia thiab flagella kuj yog cov qauv membranous. Cov qauv ntawm ob qho tib si cilia thiab flagella zoo ib yam. Flagella yog cov qauv ntev thaum cilia yog cov qauv luv. Ib lub cell feem ntau muaj ib lub flagellum lossis 2 flagella, tab sis nws muaj ntau tus cilia. Ob qho tib si cilia thiab flagella nyob ib puag ncig los ntawm chav tsev membrane uas muaj 9 + 2 kev npaj nrog 2 lub hauv paus singlet microtubules thiab 9 khub ntawm peripheral microtubules. Prokaryotic hlwb kuj muaj flagella. Flagella hauv cov hlwb prokaryotic tsis muaj 9+2 kev npaj.
Nom Membranous Organelles yog dab tsi?
Organelles uas feem ntau tsis muaj daim nyias nyias yog ribosomes, cytoskeletal lug, centrioles, cilia, thiab flagella. Ribosomes muaj nyob rau hauv ob qho tib si prokaryotic thiab eukaryotic hlwb. Lawv yog cov khoom me me zoo li granule. Lawv tuaj yeem pom nyob qhov twg hauv cytoplasm. Ribosomes muaj 2 hom, 70s thiab 80s. Prokaryotes muaj 70S ribosomes thaum eukaryotes muaj 80S ribosomes.
Cytoskeleton muaj ob hom tsis-membranous Cheebtsam. Cov no yog microfilaments thiab microtubules. Tag nrho peb cov qauv tsis muaj ib chav tsev membrane. Microtubules yog hollow thiab cylindrical qauv. Lawv yog cov zoo heev unbranched lug. Microtubules yog cov hlab ntsha protein ua los ntawm tubulin protein. Microfilaments yog unbranched khoom zoo li tus pas nrig. Lawv yog cov protein fibers ua los ntawm actin protein.
Daim duab 02: Ribosome
Centrioles kuj yog cov organelles uas tsis yog membranous muaj li ntawm triplets ntawm microtubules, uas yog teem ib ncig ntawm ib kab noj hniav. Tsis muaj lub hauv paus microtubules. Li no, lawv qhia 9 + 0 kev npaj ntawm microtubules. Ntxiv mus, tsuas yog tsiaj hlwb muaj centrioles. Cov nroj tsuag tsis muaj centrioles. Feem ntau ob lub centrioles teem rau ib leeg. Ib khub ntawm centrioles hu ua centrosome.
Dab tsi yog qhov zoo sib xws ntawm Membranous thiab Nonmembranous Organelles?
- Ob leeg membranous thiab nonmembranous organelles muaj nyob rau hauv lub hlwb.
- Tsis tas li, ob leeg ua haujlwm tseem ceeb hauv lub hlwb.
- Dhau li ntawd, ob hom muaj nyob rau hauv eukaryotic hlwb.
Qhov txawv ntawm Membranous thiab Nonmembranous Organelles yog dab tsi?
Membranous thiab nonmembranous organelles yog ob hom cell organelles. Membranous organelles tsuas muaj nyob rau hauv eukaryotic hlwb. Yog li, lawv tsis nyob hauv cov hlwb prokaryotic. Ntawm qhov tod tes, nonmembranous organelles muaj nyob rau hauv ob qho tib si prokaryotic thiab eukaryotic hlwb. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm membranous thiab nonmembranous organelles. Membranous organelles muaj ib daim nyias nyias qhwv lawv thaum nonmembranous organelles tsis muaj daim nyias nyias nyob ib ncig ntawm lawv. Li no, nws yog qhov sib txawv ntawm cov khoom membranous thiab nonmembranous organelles.
Cov duab hauv qab no ntawm qhov sib txawv ntawm membranous thiab nonmembranous organelles qhia cov kev sib txawv no piv.
Summary – Membranous vs Nonmembranous Organelles
Ib lub cell muaj ntau hom organelles. Ntawm lawv, qee qhov yog membranous thaum qee qhov tsis muaj membranous. Txawm li cas los xij, membranous organelles tsuas muaj nyob hauv cov hlwb eukaryotic xwb. Ntawm qhov tod tes, nonmembranous organelles muaj nyob rau hauv ob qho tib si prokaryotic thiab eukaryotic hlwb. Membranous organelles muaj ib daim nyias nyias nyob ib puag ncig lawv thaum nonmembranous organelles tsis muaj daim nyias nyias. Li no, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm membranous thiab nonmembranous organelles.
