The mineral cleavage is made up of many other particles to form a rock when the rock cleavage is just a rock.
A rock such as quartzite or marble consists of basically one mineral. So yes, a rock could consist of a single mineral, although most definitions describe a rock as consisting of combinations of minerals.
