What's the difference between $(this) and this in jQuery?

In jquery selector, the example code is:

<body>
  <select name="garden" multiple="multiple">

    <option>Flowers</option>
    <option selected="selected">Shrubs</option>
    <option>Trees</option>
    <option selected="selected">Bushes</option>

    <option>Grass</option>
    <option>Dirt</option>
  </select>
  <div></div>
<script>

    $("select").change(function () {
          var str = "";
          $("select option:selected").each(function () {
                str += $(this).text() + " "; // I interested it this line
              });
          $("div").text(str);
        })
        .trigger('change');
</script>

</body>

In the example code, there is a portion of code:

str += $(this).text() + " ";

I am wondering, why here does not use str += this.text() + " ";? In another word, why not use this but use $(this) in that portion of code? what is the difference between this and $(this) in this circumstance?

    jQuery’s each function sets this to the raw DOM element for each call to the iteration callback (docs). Calling $() on that raw element gives you a jQuery object wrapped around it, giving you access to the jQuery functions such as text.
