Meristematic ntaub so ntswg yog pom nyob rau hauv ntau qhov chaw, nrog rau 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 epidermis ntawm dicotyledonous ntoo thiab shrubs (cork cambium), thiab nyob rau hauv lub pericycle ntawm

Ntawm no, qhov twg yog qhov meristem pom nyob rau hauv cov nroj tsuag?

Meristems raug cais los ntawm lawv qhov chaw nyob hauv cog raws li apical ( nyob nyob rau hauv paus thiab tua cov lus qhia), lateral (nyob rau hauv lub vascular thiab cork cambia), thiab intercalary (ntawm internodes, los yog qia cheeb tsam ntawm qhov chaw ntawm nplooj txuas, thiab nplooj hauv paus, tshwj xeeb tshaj yog ntawm tej yam monocotyledons-piv txwv li, nyom).

Ib sab saum toj no, qhov twg koj xav kom pom cov ntaub so ntswg meristematic? Qhov chaw ntawm Thawj Tswj Hwm Meristematic ntaub so ntswg Cov nodes intercalary yog nyob nruab nrab ntawm thaj chaw ntawm kev loj hlob, zoo li thaj tsam sib koom ua ke ntawm cov nroj tsuag. Thiab nyob rau hauv dicots, los yog nroj tsuag nrog ob nplooj nplooj, thawj cov ntaub so ntswg meristematic muaj nyob rau hauv cov cheeb tsam apical - cov lus qhia ntawm cov hauv paus hniav, tua, thiab nplooj thiab paj buds.

Ib yam li ib tug yuav nug, dab tsi yog cov ntaub so ntswg meristem hauv cov nroj tsuag?

Meristematic cov ntaub so ntswg, los yog yooj yim meristems , yog cov ntaub so ntswg uas cov hlwb nyob mus ib txhis hluas thiab faib nquag thoob plaws hauv lub neej cog . A cog muaj plaub yam meristems : lub apical meristem thiab peb hom lateral-vascular cambium, cork cambium, thiab intercalary meristem.

Vim li cas cov ntaub so ntswg meristem tseem ceeb?

Nroj tsuag tsim cov kab mob tshiab (stems, nplooj, paj, hauv paus) ntawm cell division thiab cell txawv. Vim lub hauv paus ntawm tag nrho cov hlwb tshiab nyob rau hauv ib tsob nroj yog cov meristem , qhov no ntaub so ntswg play ib tseem ceeb lub luag haujlwm hauv kev loj hlob ntawm lub cev thiab.
