Question

The perisarc around the blastostyle forms a transparent
cylindrical capsule called...
Gonopore
Zooids
Hydrorhiza
Gonotheca​

Answer 1

Answer:

gonotheca

The pericarp, covering the blast style, forms a loose, transparent, vase-like capsule called the gonotheca. The blast style, by lateral asexual budding, produces sexual zooids called medusae or gonophores.

Answer 2

In Obelia, perisarc around the blastostyle forms a transparent cylindrical capsule called gonotheca

• In obelia, the polyps cover themselves with a secretion of chitin called perisarc which acts as an exoskeleton and plays a role in protection.
• The perisarc which surrounds the blastostyle is known as gonotheca. Gonotheca and blastostyle are together known as gonangium.

Thus, The perisarc around the blastostyle forms a transparent cylindrical capsule called (Option 4) Gonotheca.
