What phyla lack organs And what type of symmetry do they have?
Phyla such as Porifera (sponges) lack organs and have asymmetrical or no specific body symmetry. Another example is Placozoa, which also lack organs and have asymmetrical body shapes.
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 groups of organisms are more closely related group one earthworm spider jellyfish group two frog trout centipede?
Group one (earthworm, spider, jellyfish) are more distantly related compared to group two (frog, trout, centipede) because group two share a more recent common ancestor. This is because frog, trout, and centipede are all part of the same phylum Chordata, whereas earthworm, spider, and jellyfish are part of different phyla (Annelida, Arthropoda, and Cnidaria, respectively).
What do Radial and Bilateral have in common?
Symmetry in biology is the balanced distribution of duplicate body parts or shapes. The body plans of most multicellular organisms exhibit some form of symmetry, either radial symmetry or bilateral symmetry or "spherical symmetry". A small minority exhibit no symmetry (are asymmetric).
How does the biradial symmetry of certain organisms contribute to their overall survival and adaptation in their respective environments?
The biradial symmetry of certain organisms allows them to efficiently capture food and navigate their surroundings. This symmetry helps them adapt to different environmental conditions by enabling them to move and feed effectively, ultimately increasing their chances of survival.
Is a hydra a plant or an animal?
A hydra is an invertebrate animal.
Does a brain coral have bilateral symmetry radial symmetry or is it asymmetrical?
No, anything in phylum Cnidaria (including corals) have radial symmetry
Which creatures have radial symmetry?
Animals in the phyla Cnidaria and Echidnodermata (for example starfish and jellyfish) have radial symmetry.
How are worms and sponges different?
Worms are multicellular organisms belonging to the animal kingdom, while sponges are multicellular organisms belonging to the animal phylum Porifera. Worms have bilateral symmetry and a digestive system, while sponges lack symmetry and have a porous body structure supported by spicules or spongin fibers.
What phylum has radial symmetry as adult?
The phylum Echinodermata has radial symmetry as adults. These organisms include sea stars, sea urchins, and sand dollars, among others. Radial symmetry means that body parts are arranged around a central axis, like the spokes of a wheel.
Does a jellyfish have bilateral or radial symmetry?
A jellyfish has radial symmetry. A jellyfish is part of the cnidaria species of animals and they generally have radial symmetry. Radial symmetric organisms are like a pie in terms of their shape. THey have no left or right sides. If you were to turn a radial symmetric animal on its side, it would like the same as it did prior.
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.
Is a red beard sponge radial or bilateral?
sponges have no symmetry animals with radial symmetry are radiata and cnidaria, like jellyfish
What type of symmetry do cnidaria have?
Radial symmetry.other animals (exept sponges) and other exeption have bilateral symetry. bilateral symmetrical animals have up and down side, and a front and a back leaving left and right the same. radial animals only have an up side and down side, they do not have a fornt and back side.radial symmetry
What are the 9 major animal phyla characteristics and give an example?
CLASSES: Porifera, Arthropoda, Cnidaria, Chordata, Echinodermata, Nematoda, Platyhelminthesis, Annelida, Mollusca. CHARACTERISTICS: - Multi-cellular - Autotrophic -Have animal cells -Flexible cell membranes -No chloroplasts
What two animal phyla show radial symmetry?
The two animal phyla that show radial symmetry are Cnidaria (such as jellyfish and sea anemones) and Echinodermata (such as starfish and sea urchins). Radial symmetry means that the body parts are arranged symmetrically around a central axis, like spokes on a wheel.
Does a coral have a backbone?
Corals belong to the Phylum Cnidaria. Other animals that belong to the Phylum Cnidaria include jellyfish, hydrae, and sea anemones. Cnidaria are invertebrates (they do not have a backbone) and all have specialized cells called nematocysts that help them capture prey and defend themselves. Cnidaria exhibit radial symmetry.
