Solution
The formation of colonies in cnidarians typically occurs through asexual reproduction. Here's a step-by-step explanation for each of the options:
-
A polyp produces new polyps asexually and they all remain attached to one another, forming a colony: This is the most common way colonies are formed in cnidarians. The parent polyp, through a process called budding, produces new polyps that remain attached and live collectively. This forms a colony where each individual, or zooid, functions together as a single organism.
-
A polyp produces medusae asexually, but instead of dispersing, they settle next to each other, forming a colony: This is less common. Typically, medusae (the free-swimming stage of cnidarians like jellyfish) disperse to live solitary lives. However, in some species, medusae may settle and form a colony, although this is not the norm.
-
Several planula larvae settle together and remain attached to each other, forming a colony: This is also possible, but not the typical way colonies form. Planula larvae are the result of sexual reproduction and usually disperse widely to form new, solitary polyps. However, in some cases, they may settle together and form a colony.
So, the most accurate answer would be "A polyp produces new polyps asexually and they all remain attached to one another, forming a colony."
