why contamination can occur in the plant tissue culture...?

what do u mean?!!
there are hundreds of causes for contamination: the explant is already contaminated so that's why we have to sterile it first, culturing tools can be contaminated, the air around u, incubators sometimes, the media is a good nutritional source for many microrganisms and must be sterilized.....u can think of more and more

Because bacteria is easy to grow.

This is almost like the 'Why did the chicken cross the road?' question.
