Answer 1

1.In pour plate method,the molten agar is poured on to.the innoculum, this method is followed to count number of colony forming bacteria present in the liquid specimen.It helps in identifying various bacterias as aerobes,anaerobes,or facultative anaerobes.in pour plate it allows quantifying the colony forming units of bacteria in sample. In spread plate innoculum is spread on to the solidified agar.it doesn't allow the allow the growth of microaerphiles. The main difference between the two is the purpose and preparations

2.The reason why we find more colonies on spread plate is because in this method,bacteria growth is only on the surface of the medium,there is even distribution of colonies,and in spread plate it helps isolating specific clonal colonies .
