Question
How are colonies formed in cnidarians?Multiple choice question.A polyp produces medusae asexually, but instead of dispersing, they settle next to each other, forming a colony.Several planula larvae settle together and remain attached to each other, forming a colony.A polyp produces new polyps asexually and they all remain attached to one another, forming a colony.
Solution
The correct answer is: A polyp produces new polyps asexually and they all remain attached to one another, forming a colony.
Here's the step-by-step explanation:
-
The process begins with a single polyp. Polyps are the sessile, or non-moving, stage in the life cycle of a cnidarian.
-
This polyp then begins to reproduce asexually, often through a process called budding. In budding, a new organism develops from an outgrowth, or bud, due to cell division at one particular site.
-
The "bud" grows by means of cell division, resulting in a new individual, or "daughter polyp."
-
Instead of detaching and living independently, the daughter polyp remains attached to the parent.
-
This process repeats, with each new polyp remaining attached to the colony. Over time, this results in a large colony of genetically identical polyps.
-
These colonies can be quite large, and some marine species form colonies that are several feet in diameter.
