1. Form of reproductive polyps.

2. Growth in mature polyp Form of reproductive polyps.

Explanation:

The Obelia life cycle begins when two jellyfish buttons of opposite sexes undergo meiosis forming the female and male gametes. The male gamete will fertilize the female gamete, forming a zygote. The cells of the zygote will grow into a structure called Planula that will develop and form a mature popolis (a structure that looks like a stem with roots that hold it to the rocky part of the ocean), the mature propolis means that it is able to reproduce itself. if so, it will form reproductive propolis.
