Biology 1
Bakteriya(lot.bacteria -tayoqcha) xlorofilsiz bir hujayrali bakteriyalar, o'zining biologik xususiyatiga ko'ra prokariotlarga kiritiladi.
Bakteriyaning o 'Ichami
mikrometrlarda (mkm)o ich anadi. Ko'pchilik bakteriyalarning hajmi O ,2-10 mkm ga to'g“ri keladi.

Tugunak bakteriyalar
Tuganak bakteriyalar
(Rhizobium)-dukkakli
o'simliklar (beda,bersim,
no'xat va boshqalar)nish
ildizlarda to'planadigan va havodagiazotnio'zlashtirish xususiyatiga ega bo'lgan
aerob bakteriyalarturkumi

Tuproqni azot bilan
boyitadi.Yosh Tuganak bakteriyalar iddiz
tukchalariga kirib,ularni azot bilan ta'minlaydi,ilc hujayralarining jadal
bo'linishiga ta'sir
ko'rsatadi,o'simliklardan

nitrogen (N₂) from air
Biology I
Tuganak bakteriyalar
molekulyar azotni tez
biriktiradigan bakteriodlar hosil
qiladi,yo'g'onlashadi,
tarmoqlashadi.Ildizida
tuganaklari bo'lgan dukkakli
o'simliklar havodan bir ga
maydondayiliga 10 kg dan ortiq
azot to'playdi.
