Organisms in the phylum Bacillariophyta are known as diatoms. They are single-celled algae characterized by their unique cell walls made of silica. Diatoms play a significant role in aquatic ecosystems as primary producers and are a major component of phytoplankton.

What phylum has an internal calcareous skeleton?
The phylum Echinodermata has an internal calcareous skeleton made up of plates or ossicles. This skeleton provides support and protection for organisms in this phylum, such as sea stars and sea urchins.
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 taxon is made up of similar classes?
A phylum is made up of similar classes. Phyla are broad taxonomic groups that contain classes, which are more specific groupings of organisms with similar characteristics and attributes.
What is more specific phylum or genus?
Genus is more specific than phylum. Phylum is a high-level taxonomic rank that groups organisms based on shared body plans, while genus is a rank that groups similar species together based on shared characteristics.
Why does the amount of organisms decrease as you move from the first level of classification to the last level?
Each of the levels of classification is a subunit, which necessarily means that is has only a percentage of the whole. For example, Animalia (Animals) is a Kingdom and Chordata (Vertebrates) is a Phylum, the next level down. Now, all vertebrates are animals, but there are numerous animals that are invertebrates, such as worms, mollusks, jellyfishes, insects, spiders, etc. If you repeat this process of boxes within boxes, you will eventually get more and more specific. By the time you get to Genus and Species, you are only dealing with small levels of difference compared to Kingdoms and Phyla.
What make up the scientific name?
Living organisms are classified into Kingdoms, and then also phylum, class, order, family, genus & species.
In biology what do a group of classes make up?
several different classes make up a phylum.
Are phylum porifera made up of the some of the oldest known animal fossils?
Yes, the phylum porifera contain some of the oldest organisms because they are formed from fossilized, tiny sea organisms which were the precursors to modern life.
What phylum do roundworms belong do?
Scientific classification: Roundworms make up the phylum Nematoda.
What is a roundworms phylum?
Scientific classification: Roundworms make up the phylum Nematoda.
What type of cell make up unicellular organisms?
Eukaryotic cell make up unicellular organisms.
What genus is arthropod?
In taxonomy "arthropod" is a phylum or major division on a hierarchical tree. The 'genus' taxon is a much lower (or more detailed) division, describing fewer groups of organisms. You might say that phylum arthropoda 'contains' many genera.
Can you classify a round worm?
Roundworms make up the phylum Nematoda.
What does arthropod make up?
Arthropods collectively make up a major taxonomic classification called a phylum. Members of the phylum (Arthropoda) are characterized by segmented bodies, an exoskeleton made from chitin, and joint appendages.
Why are cells considered to be the basic unit of living organisms?
Because cells make up tissues and tissues make up organs and organs make up systems and systems make up organisms. Also unicellular organisms are considered living and they only have one cell.
What is animal tissue?
tissues that make up organs that make up organisms
How atoms make up organic compounds which make up all living organisms addressing all three domains?
how atoms make up organic compounds, which make up all living organisms, addressing all three domains.
