Final answer:
A Gastrozooid is a type of polyp found in certain cnidarian species that is adapted for capturing prey and feeding. It forms a crucial part of the organism's ability to feed, differing from other polyps like gonozooids that are involved in reproduction.
Step-by-step explanation:
A
Gastrozooid
is a type of polyp associated with certain species of cnidarians such as Obelia, which is representative of organisms that exhibit cnidarian dimorphism. A gastrozooid, as option a) 'Feeding polyp' suggests, is adapted for capturing prey and feeding; therefore, it forms a crucial element of the organism's feeding process.
All polyps in Obelia are connected through a common digestive cavity called a coenosarc. This is distinct from the second type of polyp, called a gonozooid, which has adapted for asexual budding and the production of sexual medusae. Thus, clear differences can be observed in functionality between the various types of polyps associated with such organisms. It's crucial to remember that not all polyps serve the same purpose; some, like the gastrozooid, play key roles in feeding, while others, like the gonozooid, are involved in the reproductive process.
