Plants are classified into divisions, classes, orders, families, genera, and species. Animals are classified into phyla, classes, orders, families, genera, and species. The main difference is the higher taxonomic level at which the classifications begin for plants (division for plants and phyla for animals).
Yes, Phylum is the category beneath Kingdom. In the Kingdom Animalia or Metazoa all animals are contained, further organised into phyla.
no idea what the anwser is
Do you mean, 'How many phyla are there on Earth?' There are more than 20 phyla of bacteria, over 30 phyla of animals and 12 phyla of plants. Fungi and protists, who knows.....? Add up all these phyla, and you can see there is quite a lot.
Animals are classified into different phyla based on several characteristics including the body symmetry (radial or bilateral), the presence or absence of a backbone (vertebrate or invertebrate), the type of body plan (sponges, cnidarians, mollusks, arthropods, etc.), and the organization of their body systems. Additionally, characteristics like the presence of a notochord, segmentation, and the development of specialized tissues also play a role in classification.
phyla?
The Porifera, or sponges
Animals belonging to the same phyla share similar body plans and characteristics. For example, animals in the phyla Chordata, which includes vertebrates like mammals, birds, fish, and amphibians, share a notochord and dorsal nerve cord during their development.
Yes. Both are phyla.
The two phyla of animals that contain an exoskeleton are Arthropoda, which includes insects, spiders, and crustaceans, and Mollusca, which includes animals like snails and clams.
Yes en.wikipedia.org/wiki/Phylum#Animal_phyla
The first animal is thought to resemble current phyla such as sponges or cnidarians, based on genetic analyses and fossil evidence. These early animals likely had simple body plans and lacked complex features seen in more derived phyla.
