Meristematic hlwb muaj lub hauv paus tseem ceeb, ntom cytoplasm thiab tsis muaj vacuoles thiab vim tias: cov cells tsis khaws cov khoom noj lossis cov khoom pov tseg. Yog li lawv tsis muaj vacuole. Raws li vacuoles muaj cell sap thiab muab rigidity thiab turgidity rau lub cell.
Vim li cas cov hlwb meristematic muaj qhov ntom ntom cytoplasm thiab cov nucleus tseem ceeb?
Kev muaj ntau lub hlwb muaj cov cim ntom ntom nti, yog li lawv xav tau cytoplasm thiab nucleus los tswj lawv cov haujlwm
Vactse muaj cov haujlwm ntawm khaws cov zaub mov, tab sis nyob rau hauv meristematic cov ntaub so ntswg, hlwb txuas ntxiv faib thiab lawv tsis tas yuav khaws cia dab tsi.
Vim li cas cov ntaub so ntswg meristematic muaj cov nucleus tseem ceeb tab sis tsis muaj vacuole?
a) Meristematic cov ntaub so ntswg sib faib tsis tu ncua thiab lawv muaj cov nucleus tseem ceeb thiab dese cytoplasm. Vim lawv dhia dej nruj heev lawv yuav tsum tsis txhob khaws khoom noj lossis khoom pov tsegyog li lawv tsis muaj vacuoles.
Cov ntaub so ntswg meristematic puas muaj cov nuclei tseem ceeb?
Meristematic cells muaj prominent nucleus thiab ntom cytoplasm tab sis lawv tsis muaj vacuole.
Vim li cas cov ntaub so ntswg meristematic tsis muaj nucleus?
Meristematic cells yog cov hlwb uas faib ntau zaus. … Meristematic hlwb muaj peev xwm sib faib. Rau lub hom phiaj no, lawv muaj tuab cytoplasm thiab nyias nyias phab ntsa. Vim li no, meristematic hlwb lack vacuole.
Pom zoo:
Thaum twg cov ntaub so ntswg meristematic pom hauv cov nroj tsuag?
Meristematic cov ntaub so ntswg muaj nyob rau hauv ntau qhov chaw, suav nrog ze rau cov lus qhia ntawm cov hauv paus hniav thiab stems (apical meristems), nyob rau hauv lub buds thiab nodes ntawm stems, nyob rau hauv lub cambium ntawm lub xylem thiab phloem nyob rau hauv cov ntoo dicotyledonous thiab shrubs, nyob rau hauv lub epidermis ntawm dicotyledonous ntoo thiab shrubs (cork cambium), thiab nyob rau hauv pericycle ntawm … Vim li cas cov ntaub so ntswg meristematic
Vim li cas cov ntaub ntawv tseem ceeb tseem ceeb rau kev tswj hwm tebchaws Askiv?
Cov ntaub ntawv raug cai ntawm cov thawj coj hauv tebchaws Askiv ua haujlwm qhov tseem ceeb ntawm keeb kwm ntawm no lub sijhawm. Cov thawj coj hauv tebchaws Askiv ntseeg tias txhua qhov kev qhia, kev npaj, txoj cai, kev txiav txim siab, kev pom zoo, kev tshawb nrhiav yuav tsum tau sau kom meej.
Puas cov ntaub so ntswg meristematic tsis muaj?
Meristematic hlwb muaj peev xwm sib faib. Rau lub hom phiaj no, lawv muaj tuab cytoplasm thiab nyias nyias phab ntsa. Vim li no, meristematic hlwb lack vacuole . Puas tsis nyob hauv cov ntaub so ntswg meristematic? Meristematic hlwb feem ntau cuam tshuam nrog kev faib cell.
Puas yog cov ntaub so ntswg adipose suav tias yog cov ntaub so ntswg txuas?
Adipose cov ntaub so ntswg, lossis cov ntaub so rog, cov ntaub so ntswgsuav nrog cov roj ntsha tseem ceeb (adipose hlwb, lossis adipocytes), tshwj xeeb los ua ke thiab muaj cov roj loj loj, hauv cov qauv network ntawm fibers . Puas yog cov ntaub so ntswg adipose txuas?
Vim li cas cov cim tseem ceeb tseem ceeb?
Background. Cov cim tseem ceeb yog qhov tseem ceeb cov ntsiab lus ntawm kev saib xyuas tus neeg laus lossis tus menyuam qhov kev vam meej thaum mus pw hauv tsev kho mob, vim lawv tso cai rau kev tshawb pom sai ntawm kev rov qab los qeeb lossis cov xwm txheej tsis zoo.
