Meristematic cov ntaub so ntswg yog cov hlwb lossis pab pawg hlwb uas muaj peev xwm faib. … Meristematic cov ntaub so ntswg yog tus cwj pwm los ntawm cov hlwb me, cov phab ntsa nyias nyias, cov cell nuclei loj, tsis muaj los yog cov vacuoles me, thiab tsis muaj qhov sib txuam.
Pob cov hlwb meristematic muaj nucleus?
Meristematic cells muaj a tseem ceeb nucleus thiab ntom cytoplasm tab sis lawv tsis muaj vacuole.
Pob cov hlwb meristematic muaj vacuoles?
Meristematic hlwb muaj peev xwm faib tau zoo heev. Lawv muaj cov cytoplasm ntom ntom thiab cov phab ntsa nyias nyias rau lub hom phiaj no. Meristematic hlwb, vim li ntawd, lack a vacuole.
cov hlwb meristematic yog dab tsi?
Muaj peb lub meristems: lub protoderm, uas yuav dhau los ua epidermis; hauv av meristem, uas yuav tsim cov ntaub so ntswg hauv av suav nrog parenchyma, collenchyma, thiab sclerenchyma hlwb; thiab cov procambium, uas yuav dhau los ua cov ntaub so ntswg vascular (xylem thiab phloem).
YPob cov hlwb meristematic muaj ribosomes?
Ribosomes, thaj chaw nyob hauv qhov ntxhib endoplasmic reticulum, yog cov chaw tsim khoom protein ntawm cov hlwb, thiab tus nqi ntawm ribosome biogenesis yog ncaj qha cuam tshuam, hauv proliferating meristematic hlwb, nrog rau kev loj hlob ntawm tes tsim nyog. rau cell division [24, 25].
Pom zoo:
Puas yog cov hlwb meristematic muaj cov phab ntsa ntawm cov cell thib ob?
Cov phab ntsa ntawm cov hlwb meristematic yog hom feem ntau raug xaiv los ua cov phab ntsa thawj (Bailey, 1940). Kev saib xyuas zoo tshaj plaws tau muab rau cov phab ntsa ntawm cov hlwb sib txawv ntau dua, tshwj xeeb tshaj yog rau cov hlwb fiber ntau uas muaj kev lag luam tseem ceeb.
Puas yog cov hlwb meristematic muaj nucleus?
Meristematic cov ntaub so ntswg yog tus cwj pwm los ntawm cov hlwb me, cov phab ntsa nyias nyias, cov cell nuclei loj, tsis muaj lossis me me vacuoles, thiab tsis muaj qhov sib txuas ntawm tes. Vim li cas cov hlwb meristematic muaj cov nuclei loj?
Vim li cas cov hlwb meristematic muaj ntom cytoplasm?
Meristematic hlwb muaj ntom cytoplasm thiab tseem ceeb nuclei vim lawv nquag faib cov hlwb, yog li lawv xav tau cytoplasm thiab nucleus los tswj lawv cov dej num. Vacuole muaj kev ua haujlwm ntawm kev khaws cov zaub mov, tab sis hauv cov ntaub so ntswg meristematic, cov hlwb txuas ntxiv rau kev faib thiab lawv tsis tas yuav khaws ib yam dab tsi.
Puas yog cov hlwb meristematic muaj nyob rau hauv lateral buds?
Meristematic cov ntaub so ntswg muaj nyob rau hauv ntau qhov chaw, suav nrog nyob ze ntawm lub tswv yim 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 dicotyledonous ntoo thiab shrubs, nyob rau hauv lub buds thiab nodes ntawm stems.
Puas yog cov paj hlwb genitofemoral yog cov paj hlwb peripheral?
Cov paj hlwb genitofemoral hais txog paj hlwb uas pom hauv plab. Nws cov ceg, ceg ntawm qhov chaw mos thiab cov ceg femoral muab kev nkag siab rau sab sauv sab xub ntiag, nrog rau daim tawv nqaij ntawm lub qhov quav sab hauv ntawm cov txiv neej thiab mons pubis hauv cov poj niam.
