sponges
cnidarians
are covered in pores

live in fresh water
have a network of nerve cells

Among Sponges and Cnidarians, the difference among given facts is in "Have a network of nerve cells".

Explanation:

Both Sponges and Cnidarians have pores, they reproduce by buddings, and they live in freshwater. The major difference in both organisms is that: cnidarians have very simple nervous system made of sensory nerves that are arranged in the form of neural network. On the other hand, sponges are simple multicellular organisms without any neural network at all. In fact, they are the only multicellular organisms (animals) without a nervous system.

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.

d. organisms have cells with different shapes and functions.
