Is a free swimming form of a cnidarian called a polyp?
No, a free swimming form of a cnidarian is called a medusa. Polyps are typically attached to a substrate and have a cylindrical body with a mouth surrounded by tentacles at one end. Medusae have a bell-shaped body with tentacles hanging down.
What are the two body forms of cnidarians?
The two body forms of cnidarians are the polyp and the medusa. Polyps are typically sessile, tube-shaped organisms attached to a substrate, while medusae are free-swimming, umbrella-shaped organisms.
Identify the organisms that exist as either medusa or polyp form?
Jellyfish exist as either a medusa (adult free-floating) or polyp (immature attached) form during their life cycle. Another example is the Portuguese Man o' War, which also has a medusa (floating) and polyp (attached) stage.
Which phylum has both medusa and polyp stages in its life cycle?
Cnidaria is the phylum that exhibits both medusa and polyp stages in its life cycle. Medusae are the free-swimming form, while polyps are typically attached to a substrate.
What is the dominant stage of the cnidarian shown in the transparency?
The dominant stage of cnidarians is the polyp stage. Polyps are typically attached to a substrate and have a cylindrical body with tentacles surrounding a central mouth. They are the primary stage for feeding and reproduction in the life cycle of cnidarians.
What is attached body form of Cnidarian?
polyp
What is a cnidarian attached to a rock called?
polyp
What are the 2 distinct life stages of cnidarians?
The medusa (jellyfish like) and the polyp (sea anenome like)
Is star coral a polyp or a Medusa?

Do you think that the polyp stage or the medusa stage predominated in the ancestral cnidarian what implications does your answer have when interpreting the evolutionary relationships among the cnidari?

What are two body forms in the phylum cnidarian?
The two body forms in the phylum Cnidarian are the polyp and medusa. Polyps are usually stationary, with a cylindrical body and tentacles surrounding a central mouth. Medusas are free-swimming and have a bell-shaped body with tentacles hanging down.
Describe the life cycle of a typical cnidarian Be sure to include the alternation of the polyp form with the medusa form?
The life cycle of a typical cnidarian involves an alternation between two main forms: the polyp and the medusa. The polyp is a sessile, asexual stage that attaches to a substrate, often reproducing by budding to form new polyps. In contrast, the medusa is the free-swimming, sexual stage that produces gametes through sexual reproduction. Fertilization results in a planula larva, which eventually settles and develops into a new polyp, completing the cycle.
Identify the organisms that exist as either medusa or polyp form?
Jellyfish exist as either a medusa (adult free-floating) or polyp (immature attached) form during their life cycle. Another example is the Portuguese Man o' War, which also has a medusa (floating) and polyp (attached) stage.
What is the evolution of a polyp into a Medusa?
Within a life cycle, a cnidarian transitioning between a polyp and a medusa is not evolution. Evolution happens over many generations, not within a single one. How the two forms evolved to both take place within a single life cycle is not well understood.
What has a vase shaped cnidarian body type?
It is a polyp. Good question!
