Properly citing your sources is absolutely necessary in order to assign credit to appropriate sources of information and to avoid committing plagiarism! This is an important responsibility that you must fulfill!
What is plagiarism? According to the Oxford English Dictionary, plagiarism is "The action or practice of taking someone else's work, idea, etc., and passing it off as one's own." This applies to written works, music, art, and other created or composed works. If you use any portion of another person's work, including ideas, words, phrases, sentences, paragraphs, lyrics, music, images, etc, without giving them credit, you are essentially representing their work as your own. This is plagiarism. Even if you commit plagiarism unintentionally by accidentally forgetting to cite a source, it is still plagiarism and it is still illegal!
