The phylum Porifera (sponges) is the only animal phylum that lacks true tissues and symmetry. Sponges are simple multicellular organisms with specialized cells, but they do not have tissues that are organized into distinct structures like other animals. Additionally, sponges exhibit asymmetry rather than bilateral or radial symmetry found in other phyla.
Porifera, which includes sponges, do not have true germ layers like other animals. They lack specialized tissues and organs, making them the simplest multicellular organisms.
Porifera, Cnidaria (Coelenterata), Ctenophora, Annelida, Platyhelminthes, Nematoda, Arthropoda, Mollusca, Echinodermata, Chordata, and several other smaller phyla Answer From above SOme of these smaller phyla include Kinorhyncha Rotifera Hemichordata Ectoprocta Sipuncula Phoronida Echiura Nemertea Tardigrada Entoprocta Chaetognatha Priapulida Acanthocephala Pogonofera Brachiopoda Onychophora
Ginkgophyta is the phylum of gymnosperms that includes only a single living species, which is the Ginkgo biloba tree.
The only grouping of animals larger than a phylum is the Kingdom, which is the highest taxonomic rank in the hierarchical classification of organisms.
No, each organism is classified into only one phylum based on its structural and genetic characteristics. The phylum is a higher taxonomic rank that groups organisms based on shared characteristics.
No, they are sponges. Actually they are the only animal phyla that does not have any "true tissues".
they are the only animal that dont have a phylum
What is a fatty substance found only in animal tissues
The phylum Porifera is the same thing as sponges. Sponges have no symmetry, which is different from all other animals. They reproduce asexually, and only have a couple of types of tissues, which they use to capture and digest nutrients in the water.The animals belonging to porifera are just combination of cells with loose organization. They do not have well defined mechanism to transport material inside. They use diffusion for this purpose. There are very less no. of tissues.
bilateral symmetry
Huh? You are an animal with bilateral symmetry. Check how many directions you are able to move.
the scientific phylum name is Cnidaria. this includes animals such as jellyfish, anemone, and coral. Some are medusa shaped (jellyfish) or polyp shaped (upside down jellyfish) All of them have nematocysts which is a scientific name for stinging cells. These invertebrates evolved from sponges. New characteristics include movement (sponges move but only at the larval stage) and tissues for the movement (muscle and nerve tissue). They also evolved from asymmetrical symmetry (sorry - redundant) to radial symmetry.
The White Tiger is apart of the phylum chordata. The white tiger possesses a notochord that stiffens the dorsal or the animals back. Not only does it have a notochord, but it has 3 germ layers, it has bilateral symmetry, and it has a complete digestive system.
An animal whose body can only be divided in one plane to show mirror images is said to exhibit bilateral symmetry. Bilateral symmetry means that the animal has a distinct front and back, a top and bottom, and two sides that are mirror images of each other. This type of symmetry is characteristic of most animals, including humans, and allows for the development of specialized appendages, such as arms and legs, which are important for movement and manipulation of the environment.
Nematocysts are are only found in the animal phylum Cnidaria, which includes sea anemones, corals, and jellyfish.
Plant tissues are made up of cellulose and provide structural support to the plant, while animal tissues are composed of proteins and serve various functions like movement, coordination, and support. Plant tissues consist mainly of cells with a rigid cell wall, whereas animal tissues are composed of cells that may or may not have a cell wall. Plant tissues are typically organized into vascular, dermal, and ground tissues, while animal tissues are classified into epithelial, connective, muscular, and nervous tissues.
