Cov yam ntxwv tseem ceeb ntawm Cyanophyceae:

• Cov hlwb ntawm tus kheej yog prokaryotic hauv qhov xwm txheej.
• Ob qho tib si vegetative thiab reproductive cells yog non-flagellate.
• Cell phab ntsa yog tsim los ntawm microfibrils thiab sib txawv ua plaub (4) txheej.
• Locomotion feem ntau tsis tuaj, tab sis thaum tshwm sim, nws yog gliding lossis jerky hom.

Ib yam li ntawd, nws tau nug, dab tsi yog prokaryotic nta ntawm Cyanophycean cell?

Zoo li lwm yam prokaryotes , cyanobacteria tsis muaj cov membrane-bound nucleus, mitochondria, Golgi apparatus, chloroplasts, thiab endoplasmic reticulum. Txhua tus muaj nuj nqi nqa tawm nyob rau hauv eukaryotes los ntawm cov membrane-bound organelles yog nqa tawm nyob rau hauv prokaryotes los ntawm cov kab mob ntawm tes daim nyias nyias.

Qhov thib ob, dab tsi yog qhov qhia txog tus yam ntxwv ntawm cyanobacteria? Txhais cov yam ntxwv ntawm cyanobacteria yog ib qho kam rau ntawm cov xwm txheej hnyav thiab muaj peev xwm muaj nyob tsis muaj cov vitamins. Lawv siv phosphorus, hlau thiab lwm yam micronutrients, thiab ammonia lossis nitrate ua cov khoom siv nitrogen. Qee hom cyanobacteria cov yog filamentous thiab tsis xav tau hnub ci.

Tsis tas li ntawd, dab tsi yog yam ntxwv ntawm cyanophyta?

Cov yam ntxwv dav dav Cyanophyta

• ua prokaryotic.
• Lub cev unicellular los yog multicellular.
• Muaj chlorophyll, yog photoautotrophs.
• Habitat cosmopolitan (pom nyob txhua qhov chaw)
• Qee tus nyob hauv symbiosis nrog lwm cov tsiaj muaj sia.
• Tus yug asexually.

Vim li cas Cyanophyceae hu ua cyanobacteria?

Vim lawv yog photosynthetic thiab dej, cyanobacteria cov feem ntau hu ua " xiav-ntsuab algae ". Lub npe no yooj yim rau kev hais txog cov kab mob hauv cov dej uas ua rau lawv tus kheej cov zaub mov, tab sis tsis muaj kev cuam tshuam txog kev sib raug zoo ntawm cov dej. cyanobacteria cov thiab lwm yam kab mob hu ua algae.
