Bryophytes - Thawj thaj av nroj tsuag tom qab cov algae uas nyob ntawm ntug pas dej thiab cov kwj deg yuav muaj ua bryophytes . Bryophytes muaj stoma thiab waxy daim tawv nqaij ntawm lawv lub cev uas pab tiv thaiv lawv ntawm dessication.
Tsuas yog li ntawd, Charophytes puas muaj cuticles?
Charophytes zoo ib yam li cov nroj tsuag niaj hnub. Kev hloov pauv mus rau thaj chaw thaj av tau ua rau tiam tom qab tiam ntawm cov nroj tsuag kom ua tiav tawm hauv dej. Cov waxy daim tawv nqaij thiab stomata tau ua haujlwm zoo hauv kev txo cov dej poob thiab tiv thaiv desiccation.
Ib sab saum toj no, puas bryophytes muaj stomata? Mauxes thiab hornworts yog qhov ntxov tshaj plaws ntawm cov av uas tseem muaj nyob rau muaj stomata , tab sis tsis zoo li cov nyob hauv tag nrho lwm cov nroj tsuag, bryophyte stomata Nws yog nyob rau ntawm sporangium ntawm sporophyte. Stomata ntawm nplooj thiab stems ntawm tracheophytes koom nrog hauv kev sib pauv roj thiab kev thauj dej.
Tsis tas li ntawd, cov kab mob no puas muaj cuticles?
Liverworts . Liverworts (Hepaticophyta) raug saib raws li cov nroj tsuag feem ntau ze ze rau cov poj koob yawm txwv uas tau tsiv mus rau hauv av. Cov nroj tsuag siv dej hla nws tag nrho saum npoo thiab muaj tsis muaj daim tawv nqaij tiv thaiv desiccation. Liverworts : A lub siab , Lunularia cruciata, qhia nws cov lobate, tiaj tus thallus.
Puas yog algae muaj cuticle?
Algae ua Tsis txhob cia lub embryo nyob rau hauv lawv tus kheej tab sis tso nws mus rau hauv dej. Qhov no yog thawj qhov kev hloov pauv uas cais cov nroj tsuag ntawm ntsuab algae . Qhov no kuj yog ib qho kev hloov pauv nkaus xwb los ntawm txhua cov nroj tsuag. Hauv cov nroj tsuag thaum ntxov, ib txheej waxy hu ua a daim tawv nqaij evolved los pab kaw dej hauv cov nroj tsuag thiab tiv thaiv kom tsis txhob poob dej.

Puas yog ib qho tsis muaj polar molecule puas muaj hydrogen bonding?
Yog hais tias lub molecule tsis yog polar, ces tsis muaj kev sib cuam tshuam dipole-dipole los yog hydrogen bonding tuaj yeem tshwm sim thiab tsuas yog ua tau intermolecular quab yuam yog lub zog van der Waals tsis muaj zog
Muaj pes tsawg guanine bases puas yog 50 lub hauv paus khub ob txoj hlua DNA 100 bases tag nrho muaj yog tias nws muaj 25 adenine bases?
Yog li, muaj tag nrho ntawm 25 + 25 = 50 adenine thiab thymine hauv tag nrho. Qhov ntawd tawm 100− 50 = 50 seem hauv paus. Nco ntsoov tias cytosine thiab guanine daim ntawv cog lus nrog ib leeg, thiab yog li lawv sib npaug ntawm cov nyiaj. Tam sim no peb tuaj yeem faib los ntawm 2 kom tau txais tus lej ntawm guanine lossis cytosine hauv paus
Puas bryophytes muaj txiv hmab txiv ntoo?
Bryophytes. Bryophytes yog ib qho kev faib ntawm cov nroj tsuag uas suav nrog tag nrho cov tsis-vascular, av nroj tsuag thiab tuaj yeem faib ua peb pawg: mosses, hornworts thiab liverworts. Mosses, hornworts thiab liverworts tag nrho cov me nyuam siv spores ntau dua li cov noob thiab tsis tsim ntoo, txiv hmab txiv ntoo lossis paj
Puas yog bryophytes muaj cov ntaub so ntswg?
Mosses thiab liverworts yog lumped ua ke asbryophytes, cov nroj tsuag tsis muaj tseeb vascular ntaub so ntswg, thiab sib koom ib tug xov tooj ntawm lwm yam primitive zoo. Lawv kuj tsis muaj qhov tseeb, cov hauv paus hniav, lossis nplooj, txawm tias lawv muaj cov hlwb uas ua cov haujlwm no
Puas yog bryophytes muaj cov phab ntsa ntawm tes?
Yam ntxwv. Bryophytes yog cov nroj tsuag vim hais tias lawv yog photosynthetic nrog chlorophylls a thiab b, khw starch, yog multicellular, tsim los ntawm embryos, muaj sporic meiosis - ib tug alternation ntawm tiam - thiab cellulose cell phab ntsa
