Many rocks match that description. Try putting some vinegar on it. If it reacts with any bubbling, it is probably limestone.

how the holes may get there is from the hot lava or magma and since it is very hot it may cause the holes i am not to sure though about my answer.When rocks are heated to melting point, bubbles of gas can get trapped in them. When the rock cools, the gas is left as a hole. Volcanic rock is chock full of holes.
Pumice is full of holes called vesicles formed from gasses escaping the molten rock. The holes greatly reduce its density.
Crystals that form from supersaturated solutions need a nucleus to grow onto, either the existing crystals or a different structure.ExperimentTo grow a sugar crystal, tie a string to a pencil. Balance the pencil horizontally on top of the jar full of sugar water, with the string hanging in it. After some time (hours), crystals of sugar will precipitate onto the string.

The holes are gases from the yeast eating the sugar in the dough. These bubbles are what makes the bread light rather than solid like a cracker. As much as it may seem a bit gross, the gas is essentially yeast farts!

Homogeneous is mixed, like stirring sugar into a cup of tea or water. However, if you put one full teaspoon of sugar into 1/4 teaspoon of water, it would not mix completely-- the sugar would remain in a mostly granulated state. Or if you mixed sugar completely into a small amount of water and let the water evaporate, the sugar crystals would begin to fall to the bottom,e.g. separate from the mixture.
