Question

In Physalia, zooids occur in groups called
A. Ponulae
B. Palpons
C. Cormidia
D. Dactyloids

Answer 1

Hint:- The quiet Portuguese man-of-war (Physalia physalis) normally is a floating hydrozoan, which is actually in all fairness giant. Their motion in particular is primarily based on their type of man or woman osmotic and hydrostatic pressure, demonstrating that cnidocytes are placed within the tentacles, absolutely further displaying how the essentially Portuguese man-of-war essentially is a floating hydrozoan in a kind of important way.

Complete Answer:- An "person" specifically is a colony of for all intents and functions unisexual organisms. The gametes produced for a replica in particular are referred to as zooids, which mainly is quite great. Cormidium here refers to the for all intents and functions complete body or colony of the basic animal consisting of clusters of zooids in a diffuse manner. Each basic character essentially has pretty specific gonozooids, or so that they sort of idea. Every gonozooid is made from gonophores, which especially are kind of little sort of greater than sacs containing either ovaries or testes. Their larvae likely in reality expand very hastily to small floating forms. Fertilization of P. physalis form of is believed to especially occur in the pretty open water, due to the fact gametes from the gonozooids type of are for the most part shed into the water, demonstrating how cormidia here refers back to them without a doubt complete body or colony of the very animal which includes clusters of zooids in an, in reality, primary manner. This can appear as gonozooids themselves specifically are broken off and launched from the colony, demonstrating how this can kind of occur as gonozooids themselves for all intents and functions are broken off and launched from the colony, which for the most part is quite sizable. In Physalia, zooids occur in groups called cormidia.

Hence, the correct answer is option C

Note:- Physalia physalis mainly virtually is a siphonophore, and surely animal product of a colony of four wonderful polyps: a pneumatophore, dactylozooids, gastrozooids, and gonozooids, which usually in all fairness sincerely first-rate in a normally massive way.
