The most important phylum in eukaryotes is the phylum Chordata, which includes vertebrates like mammals, birds, reptiles, amphibians, and fish. Chordates are characterized by the presence of a notochord at some stage in their development, and they have a well-developed nervous system.

Is phylum prokaryote or eukaryote?
Prokaryotes are members of the domains Bacteria and Archaea, and they lack a true nucleus. Eukaryotes, which make up the other domain, Eukarya, have a true nucleus and other membrane-bound organelles. Phylum is a taxonomic rank that can include both prokaryotic and eukaryotic organisms.
What phylum is a whale?
It has a backbone so it's included in the phylum chordata, even most people will not think that way because they live in water.
What classification category includes the most species?
The category with the most species is the phylum. For example, there are over 1 million species in the phylum Arthropoda, which includes insects, spiders, and crustaceans.
What is the phylum of sessile animals?
The phylum of sessile animals is Porifera, which includes organisms such as sponges. Sessile animals are ones that are permanently attached to a surface and do not move around freely.
What phylum is most closely related phylogenetically to first vertebrates?
The phylum Chordata is most closely related phylogenetically to the first vertebrates. Chordates share a number of characteristics with vertebrates, such as having a notochord, dorsal nerve cord, and pharyngeal slits. Cells within the notochord further develop into the vertebrae that define vertebrates.
Most single-celled eukaryotes are currently classified as what?
A catch all Phylum called Protista. ( older name, Protozoan )
Classification of invertibrates?
Invertebrates have nucleated cells and are thus eukaryotes (Domain Eukarya in the Empire of Life). They are multicellular and heterotrophic and thus animalian (Kingdom Animalia). Edward O. Wilson is what one calls a 'splitter' in taxonomy and has split the animal kingdom into about 85 phyla. Most other taxonomists think there are somewhere in the thirties in the realm of 'How many phyla are there ?' Some invertebrate animal phyla are: Phylum Porifera, Phylum Cnidaria, Phylum Ctenophora, Phylum Platyhelminthes, Phylum Annelida, Phylum Mollusca, Phylum Arthropoda, Phylum Echinodermata, Phylum Hemichordata, Phylum Nematoda, Phylum Rotifera, Phylum Kinorhyncha, Phylum Nemertea, Phylum Bryozoa
What did eukaryotes most evolve from?
Eukaryotes most likely evolved from prokaryotes.
What phylum has jaws and skulls that are important in their evolution?
Phylum Chordata.
Explain how the phylum fits into to taxonomy system?
Phylum is the stage right below kingdom and above class. There are two categories in phylum: eukaryote, and prokaryote. Eukaryotes have a well defined cell membrane and nucleus. A prokaryote does not. This can already separate the different classes into different categories.
Why is cell division is important in eukaryotes?
It's important because that's how they reproduce.
How does phylum fit into taxonomy?
Phylum is the stage above class and below kingdom. There are two categories in phylum: eukaryote and prokaryote. Eukaryotes have well defined cell membranes and nuclei, while a prokaryote doesn't. This can already separate the different classes into different categories, which is evidently the goal of taxonomy -- to classify organisms.
Are most fungi eukaryotes?
Yes, they all are!
What applies to most protists?
unicellular eukaryotes
Most eukaryotes contain hundreds of what?
copies
What is the phylum of sessile animals?
The phylum of sessile animals is Porifera, which includes organisms such as sponges. Sessile animals are ones that are permanently attached to a surface and do not move around freely.
What structures or molecular machines are important for protein degradation in eukaryotes?
proteasome
