BACTERIA
EUBACTERIA
 TRUE BACTERIA
 WALL-MUCOPEPTIDE
 REPRODUCTION –BINARYFISSION
 CAUSE DISEASES
 COCCUS-SPHERICAL
 BACCILLUS-ROD
 SPIRILLUM-SPIRAL
 VIBRIO-COMMA
EUBACTERIA
 MAY HAVE FLAGELLA
 AUTOTROPHIC OR HETEROTROPHIC
 PHOTOSYNTHETIC OR CHEMOSYNTHETC
 CHEMOSYNTHETIC-MAKE ATP FROM
CHEMICAL ENERGY
 THEY USE AMONIA NITRITES OR NITRATES FOR
ENERGY
REPRODUCTION OF BACTERIA
• ASEXUAL-BINARY FISSION
• ENDOSPORE –DURING
UNFAVAROUBLE SEASON
• SEXUAL REPRODUCTION –BY DNA
