If you're looking through a microscope, you typically see a (sometimes odd looking) nucleus and many granules. The nucleus, of course, houses the genetic information. I'm not too certain why it's sometimes multi-lobed, but it may have something to do with facilitating the leukocyte's ability to travel through small openings. As for the granules - the exact chemical composition varies, but they play an important role in determining the function of the leukocyte. For example, the granules of your neutrophils house enzymes which break down foreign substances, whereas the granules of your basophils release histamine and other inflammatory messengers. Apart from that, you have your regular organelles (ER, Golgi, etc.)>
