Is green hydra single celled or multicellular?

But about 600 million years ago, a few one-celled creatures began to group together and cooperate to make multi-celled creatures. The first ones were probably sponges, and then hydra are the next earliest and simplest creatures with more than one cell.

What type of reproduction is hydra?

The common asexual method of reproduction by hydras is budding. Buds originate at the junction of the stalk and gastric regions. The bud begins as a hemispherical outpouching that eventually elongates, becomes cylindrical, and develops tentacles. The bud then pinches off and a new individual becomes independent.
