Because they Have many Characters of their ancestors and the word polyphyletic means those organisms which have many ancestors and because is protoctists have characters of Animals, plants and Fungi so that why they are considered as polyphyletic group.
Kingdom Protista is called polyphyletic group of organism because they do not shear their single common ancester.
they had more than one independent origin.
protoctista is a family of classification
they are both unicellular ( are single celled).

it waz first in the kingdom protoctista but now in kingdom fugus
The 5 kingdoms are: Fungi, Plantae, Protoctista, Prokaryotae, & Animalia. Algae have features of both plants and animals, but they are generally grouped in the plantae kingdom.
i dont no
Protists are a paraphyletic group because animals, fungi, and plants are the crown groups evolved from different lineages of the protists. They aren't included in the same group as protists taxonomically. This explains why the cladists consider the protist a paraphyletic group.
No, the kingdom Protista is no longer considered a legitimate taxonomic group. It is a polyphyletic group, meaning it does not include all descendants of a common ancestor. The organisms once classified in Protista have been reclassified into other kingdoms such as Plantae, Animalia, and Fungi.
yes they r polyphyletic
protoctista is a family of classification
monophyletic
Because they're descended from a common ancestor and the classified group includes all animals. The other kinds, para- and polyphyletic groups, are classified groups that have multiple ancestors (poly) or are a single group but with parts excluded (para). Carnivorous plants are polyphyletic, as they include many different genera, and reptiles are paraphyletic, because it excludes birds which are technically still reptiles.
yes
Yes
Its not polyphyletic, its monophyletic. There are no points where members stop being animals. Many mistake Porifera (sponges) as an exception, but they are animals too.
Protoctista are eukaryotic, meaning they have a true nucleus. Monera are prokaryotic, meaning they have no nucleus.
'Toads' are actually not a scientifically valid group; they are simply a common name for a number of polyphyletic, warty skinned, mainly terrestrial amphibians in the order Anura.
