Fairy king attend and mark you do hear the morning lark what does these lines mean?

In the context of A Midsummer Night's Dream by William Shakespeare, these lines spoken by Helena signify her desire for Demetrius' attention and acknowledgment. She compares Demetrius to the fairy king and implores him to pay attention to her, just as the morning lark heralds the beginning of a new day. The use of the imagery of the morning lark suggests a sense of awakening and hope, reflecting Helena's longing for Demetrius' love and appreciation.
