Top: Tentacles, mouth (hypostome)
Middle: Younger bud (smaller), older bud (bigger), testis (bumps lacking egg cells)
Bottom: Basal disc, ovary, peduncle (apparently)
Everywhere: Epidermis, mesoglea, gastrodermis, coelenteron, flagellated cells
Name the parts of Obelia starting from the top
Tentacles, perisacral annuli, medusa buds, coenosarc, gonopore, gonotheca, blastostyle, hydrocaulus
