A metanephridium (pl. metanephridia) is a type of excretory gland or nephridium found in many types of invertebrates such as annelids, arthropods and molluscs. It typically consists of a ciliated funnel opening into the body cavity or coelom connected to a duct which may be variously glandularized, folded or expanded (vesiculate) and which typically opens to the organism's exterior. These ciliated tubules pump water carrying surplus ions, metabolic waste, toxins from food, and useless hormones out of the organism through openings known as nephrostomes. This waste is passed out of the body at the nephridiopore. The primary urine produced by filtration of blood (or a similar functioning component) are modified into secondary urine through selective reabsorption by the cells lining the metanephridium. In many earthworms the nephridial ducts open into the digestive tract instead, a condition known as enteronephry.
Yes, Platyhelminths, commonly known as flatworms, possess protonephridia. These are simple excretory structures that function in osmoregulation and waste removal. Protonephridia consist of flame cells that create a current to help expel waste products and excess water from the body. This system is crucial for maintaining the internal environment of these organisms, especially in freshwater habitats.
Olive belongs to family Oleaceae of dicotyledones. In Botany we do not use the term Phylum as per norms of International code of botanical nomenclature.
Phylum Ginkgophyta
The same phylum you belong to! Chordata.
Amoeba belong to the phylum Tubulinea.
Protonephridia are found in flatworms, such as planarians. These structures are responsible for excreting waste and regulating osmotic balance in these organisms.

what is the trait you would use to a fish as belonging to either the phylum chordata or the phylum arthropada
protonephridia, metanephridia... Gills?
They belong to the phylum Cnidaria, named after the stinging cells that species in the phylum use to catch prey.
Phylum Phatyhelminth use a blind gut to transport food and waste. A blind gut means it has a mouth but no anus.
they use there thick musklar foot
Echinoderms are the phylum. The phylum is Echinodermata Echinoderms are the phylum. The phylum is Echinodermata Echinoderms are the phylum. The phylum is Echinodermata
In the Kingdom of the Animalia there is a dog, gorilla, lemur, sea star and sea squirt, but in the Phylum of the Animalia the sea star does not exist.
phylum protozoa porifera
Botanists use the term "division" in place of phylum when classifying plants. It is used to categorize plants based on their distinct characteristics and evolutionary relationships.
