How does the symmetry of a polyp form affect its ability to eat?
The symmetry of a polyp can affect its feeding strategies and efficiency. Radially symmetrical polyps like those of cnidarians can efficiently catch prey from various directions, while bilaterally symmetrical polyps like some flatworms may have specialized structures for targeted feeding. The specific structure and arrangement of feeding tentacles or openings can depend on the polyp's symmetry and can impact its ability to efficiently capture and consume food.
What is a phylum that is characterized by radial symmetry?
A phylum characterized by radial symmetry is Cnidaria. This group includes organisms such as jellyfish, corals, and sea anemones, which exhibit a body plan that is symmetrical around a central axis. Radial symmetry allows these organisms to interact with their environment from all directions, which is advantageous for their feeding and predation strategies. Cnidarians also possess specialized cells called cnidocytes, which they use for capturing prey.
What is physical characteristics of roundworm?
Roundworms are typically long, cylindrical worms with smooth, slender bodies. They have a pointed head with a mouth for feeding and a tapered tail. Roundworms can range in size from a few millimeters to several meters in length.

How do cnidarians eat?
Mainly through suspension feeding. Cnidarians use stinging tentacles (nomocytes) to capture their prey. Once the tentacles grab the food it is absorbed in the gastrovascular cavity (stomach) and taken in asnutrients.
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.
All cnidarians possess long extensions of the body called tentacles?
True, tentacles are a common feature among cnidarians like jellyfish and sea anemones. These structures are typically armed with stinging cells called cnidocytes, which help cnidarians capture prey and defend against predators. Tentacles are used for a variety of functions including feeding, sensing the environment, and locomotion.
What are the characteristics of organisms with biradial symmetry and how does this symmetry pattern contribute to their overall structure and function?
Organisms with biradial symmetry have a body plan that can be divided into two equal halves along two planes. This symmetry pattern allows for efficient movement and feeding in multiple directions. It also helps these organisms to navigate their environment and locate food sources more effectively. Overall, biradial symmetry contributes to the overall structure and function of these organisms by enhancing their ability to interact with their surroundings and adapt to different environmental conditions.
What are some examples of specialized cells present in cnidarians?
Some examples of specialized cells in cnidarians include cnidocytes (stinging cells) used for defense and capturing prey, sensory cells for detecting movement and light, and muscle cells for movement and contraction. Additionally, some cnidarians have specialized cells that secrete mucus or digestive enzymes for feeding.
Selective advantage of radial symmetry for sessile and free floating animals?
Radial symmetry is selectively advantageous because the organisms approach their environment from all sides equally. In addition to sessile animals, radial symmetry can also be found in some other animals and plants.
