Answer:
Presence or absence of cilia/stinging cells.
Numbers.
Retractability.
Number of cells.
Explanation:
Apart from size difference, tentacles in Cnidaria and Bryozoa differs such that:
- <em>The tentacles in Cnidaria have no cilia surrounding them while those of Bryozoa are ciliated. Instead of cilia, the tentacles in Cnidaria have stinging cells.</em>
- <em>Tentacles in Cnidaria are fixed in number while the number may vary in Bryozoa.</em>
- <em>Tentacles in Cnidaria are often retractable while retractability is not possible in Bryozoa.</em>
- <em>Cnidaria tentacles are made up of multiple cells while those of Bryozoa are made up of single cells.</em>
