Reproduction in bacteria

Bacteria reproduce by binary fission (not binary fusion). In

this process the bacterium, which is a single cell, divides into

two identical daughter cells.

Bacteria need warmth and food to reproduce. Some bacteria

need oxygen to breathe these are called aerobic bacteria. Oth-

er bacteria do not need oxygen theses are called anaerobic

bacteria Many anaerobic bacteria cause diseases

Respiration in bacteria

Respiration is required by living organisms to produce the en-

ergy they need to live.

Some bacteria need oxygen for respiration. These are called

aerobic bacteria

Other bacteria do not need oxygen. These are called anaerobic

bacteria

Many anaerobic bacteria cause diseases
