Can somebody plzz help me... What are the differences between female and male reproductive systems...

What species? Basically females produce an egg that can be fertilized by the male's sperm. The female generally has the plumbing to nuture the egg until its ready for birth.

Any biology textbook will explain this in detail.

As stated, any basic bio or anatomy book, available at public libraries, will explain.

GOOGLE it!!

The gonads of the male are on the outside... the gonads of the female are on the inside.

Or, you can open your book and read for yourself.
