since singing involves the whole body, and not just the bit in the throat, it's always a good idea to vocalize or warm-up the whole mechanism before seriously undertaking music.
Good warm-up should include a look at posture and breathing, phonation ( how you start and maintain a sound) and resonance ( where you feel the sound in your mouth and how you use your vowels to get there), before you ever get to a real piece of music.
Starting un warmed up is tantamount to going out for a sports match unwarmed up: the risk of damage is that much higher, and the possibility that you will not playing your best.
Some people take a bit longer than others to get their air moving, some people seemingly jump right in, but it's always good to spend 15 minutes a day warming up.

It warms up the muscles/body parts you use when singing (mouth, throat, tongue muscles, vocal cords, diaphragm) and it gets you comfortable, gets you in 'singing' mode. it clears your throat a bit if you throw humming in, and it keeps you from straining your muscles and/or voice before tackling difficult notes.

It's to warm up, but also to practice and reinforce certain vocal techniques that will eventually become part of the way you naturally sing.

When you are going a warm-up, just ask your teacher what technique that warm up is supposed to help you be learning. As voice teachers, sometimes we just forget to tell our students what the technique is, but it will help you to know and to carry it over into the music you are singing.
