Yog vim li cas yog nplooj ntsuab? Yog vim li cas lawv xav tau?

Nroj tsuag - ib tug ntawm tsib kingdoms uas muaj sia nyob rau ntawm peb lub ntiaj chaw. Lawv mus rau lub eukaryotes, piv txwv li beings uas nws hlwb muaj ib tug nucleus.

Tus qauv ntawm cov nroj tsuag

Lawv yuav ua tau unicellular los yog multicellular. Cov yav tas yog muab faib mus rau hauv khej xws li ntsuab, xim av thiab liab algae, spore, gymnosperms thiab angiosperms. algae lub cev muaj peev xwm muaj xws li ib tug tib cell, thiab ntawm lub ntau yam, tab sis nyob rau hauv lawv cov qauv muaj cov tsis muaj lub cev, cov khoom cev - hu ua lub thallus. Nyob rau hauv spore, gymnosperms thiab angiosperms (flowering nroj tsuag) pom tus xub ntiag ntawm differentiated ntaub so ntswg thiab kabmob. Tsis ntev los no muab faib mus rau hauv vegetative thiab generative. Cov yav tas los hais txog txoj kev khiav (qia thiab nplooj) thiab lub hauv paus. Muaj coob tus neeg xav tias, "Yog vim li cas nplooj ntsuab," Yog vim li cas qhov no xim? Tsis tas li ntawd, muaj ntau yam cov me nyuam nug cov lus nug: "Yog vim li cas yog ntsuab nplooj?" Thiab qhov no tsab xov xwm peb mam li pib nrog no lub npe.

Yog vim li cas yog nplooj ntsuab?

Qhov no yog xim vim lub xub ntiag ntawm chlorophyll. Nyob rau hauv lub Autumn ntawm cov xim yog poob thiab ntsuab ntawv yog hloov dua siab tshiab rau hauv liab, txiv kab ntxwv los yog daj. Vim li cas koj xav tau cov khoom no? Nws yog ib tsab tseem ceeb heev rau cov nroj tsuag. Yog tsis muaj nws yuav tsis tau mus hauv tus txheej txheem ntawm photosynthesis uas as-ham yog ua. Organic tshuaj nroj tsuag yog feem ntau tau xwb los tus txheej txheem no. Txawm li cas los, ib co hom uas nyob rau hauv lub qis khaubncaws sab nraud povtseg ntawm cov rainforest, tsis tau txaus lub teeb rau photosynthesis tag nrho, yog li resorted mus plob hav zoov rau me me kab, yog li compensating rau tus tsis muaj organic tebchaw. Cov no muaj xws sundew, poj niam txoj kev txhais khau khiab thiab thiaj li nyob. D.

Luv luv txog cov qauv ntawm cov nroj tsuag cell

Nws muaj cov ntshav membrane, lub cell phab ntsa ntawm lub cellulose, lub cytoplasm, uas muaj organelles thiab ib tug keeb uas yog DNA. Lub cytoplasm muaj xws organelles: lub mitochondria, ribosomes, endoplasmic reticulum, vacuole (nyob rau hauv lub qub tawb - ib tug loj, nyob rau hauv cov tub ntxhais - ib tug ob peb me me), lub Golgi complex, thiab plastids (chloroplasts, leucoplasts, chromoplasts). Txhua yam ntawm lawv ua nws cov nuj nqi. Mitochondria zog, ribosomes ua ke cov nqaijrog endoplasmic reticulum (reticulum) generates lipid vacuoles noog pliaj yam li lead lawv nyob nraum zoov ntawm cov khoom cell phab ntsa tsis yooj yim sua nyob rau hauv chloroplasts kis photosynthesis txheej txheem, chromoplasts muaj pigments, leucoplasts muab zeem cia cov as-ham ( yeej, qhov no cov hmoov txhuv nplej).

Yuav ua li cas yog photosynthesis?

Qhov no txoj kev yog nqa tawm nyob rau hauv lub chloroplasts, uas yog nyob rau hauv lub cytoplasm. Cov organelles yog odnomembrannymi nyob rau hauv lawv cov qauv muaj xws li thylakoids - nyias paib sau nyob rau hauv lub ntsej muag - cov pawg. Nws yog nyob rau hauv lawv thiab muaj chlorophyll - uas yog vim li cas nplooj ntsuab. Tsis tas li ntawd, chloroplasts muaj ribosomes, muab kev koom tes nyob rau hauv lub formulation ntawm cov nqaijrog, starch granule, raws li zoo raws li yeej DNA molecule, nyob rau hauv cov ntaub ntawv uas yog muab sau tseg rau cov tshuaj uas yog yuav tsum tau tsim nyob rau hauv lub cell. Nyob rau hauv tus txheej txheem ntawm photosynthesis, nroj tsuag nqus hnub ci zog, dej thiab cov pa roj carbon dioxide thiab muab tawm cov pa raws li ib tug los ntawm-cov khoom tshua. Enzymes uas pab ua tshuaj cov kev sib tshuam yog ncaj qha nyob rau hauv lub chloroplast matrix (substance sau).

Yuav ua li cas nws muaj nplooj?

Qhov no lub cev yuav ntes ob peb hom tsob nroj ntaub so ntswg, lawv plaub. Qhov no epidermis, mesophyll, kev cov ntaub so ntswg (xylem thiab phloem), thiab cov neeg kho tshuab cov ntaub so ntswg. Photosynthesis yuav siv sij hawm qhov chaw precisely nyob rau hauv lub mesophyll, los yog parenchyma. Koj yuav saib tau lub hlwb ntawm ib cov nplooj ntsuab nyob rau hauv ib tug tshuab kuaj kab mob. Qhov no sab sauv pob - lub epidermis. Hlwb twb nws txheej txheem zoo mus rau txhua lwm yam, tab sis qhov no txheej muaj pores uas tso cai rau yuav nqus cov pa roj carbon dioxide thiab tso pa, thiab kuj tswj cov dej thiab kub tshuav nyiaj li cas. Parenchyma (mesophyll) yog muab faib ua ob khaubncaws sab nraud povtseg - ib qho ntawm columnar hlwb, rau lwm yam - ntawm daim ntaub. Nyob rau hauv lub yav tas los muaj ib tug loj tus naj npawb ntawm chloroplasts tshaj nyob rau hauv lub thib ob. Xylem hlab ntsha muab los ntawm kev uas cov kua nkag los ntawm cov keeb kwm mus rau lub nplooj, i.e. upwards thiab phloem sitopodobnyh muaj hlab los ntawm kev uas cov dej yog thauj down. Neeg kho tshuab tib cov ntaub so ntswg daim ntawv muab rigidity thiab stability, kev zoo.
